[BibTeX] [Abstract] [Download PDF]

The usage of the mobile Internet increased tremendously within the last couple of years, and thereby the vision of accessing information anytime, anywhere became more realistic and a dominant design principle for providing content. However, this paper presents work-in-progress that challenges this paradigm of unlimited and unrestricted access, and explores and tests how constraints and restrictions may positively influence the motivation and enticement of mobile users to engage with location-specific content. Restrictions, such as a particular time or location that enables a user to access content, may be used to foster community participation and engagement, as well as to support locative media production and to enhance the user{‚}s experience. In the end, we outline the timeline of our current work and further studies planned in order to verify our hypothesis.

abstract = {The usage of the mobile Internet increased tremendously within the last couple of years, and thereby the vision of accessing information anytime, anywhere became more realistic and a dominant design principle for providing content. However, this paper presents work-in-progress that challenges this paradigm of unlimited and unrestricted access, and explores and tests how constraints and restrictions may positively influence the motivation and enticement of mobile users to engage with location-specific content. Restrictions, such as a particular time or location that enables a user to access content, may be used to foster community participation and engagement, as well as to support locative media production and to enhance the user{'}s experience. In the end, we outline the timeline of our current work and further studies planned in order to verify our hypothesis.},

Indoor Navigation is becoming a more and more important topic. It is a key tool for the integration of disabled people into environments which they are not familiar with. With this paper we want to address the problem of indoor navigation being much more complex than outdoor navigation with a thorough modelling of queries which a indoor navigation GIS database shall be able to answer quickly and present an organisation of indoor navigation data tailored to scalable and flexible indoor navigation.

[BibTeX] [Abstract]

Location information is the foundation for location based services. However, a cheap and global indoor positioning solution offering a sufficiently high accuracy and precision for most applications is not yet available and detains location based services from indoor areas. This is also due to missing comparability and standards in the field of indoor positioning, resulting in a large number of proprietary research prototypes of varying capabilities. In this paper we present a software environment for testing and comparing sensor fusion algorithms in indoor positioning scenarios. For this purpose an extendable tool for evaluating accuracy, precision, robustness, complexity, and storage is designed and the results from a first implementation presented and discussed.

[BibTeX] [Abstract]

In the last couple of years, the number of smartphone users has proliferated. As smartphones contain a lot of different sensors, research interest in algorithms combining data of several sensors to derive meaningful information about a user’s context, e.g. her location, is increasing. Ideas for reasonable algorithms often can be found by looking at examples of raw (or somehow pre-processed) sensor data. Still, the research community lacks a simple means to intuitively work with several parallel tracks of time series data. We present a tool which can be used to visualize and edit time dependent data from various sensors along with ground truth recordings like audio or video files. It is complemented by an optional application for logging all kinds of sensor data on Android devices. The tool has already been used to analyze a large data set containing hundreds of walking traces, intended to improve pedestrian dead reckoning algorithms.

[BibTeX] [Abstract] [Download PDF]

Location-based Access Control often relies a location proof, which ensures that a specific user is at a specific location. These locations are most often inferred from measurements. As a consequence, such systems are never trustworthy. An attacker can simply fake sensor measurements or even sensor data in absence of a trusted measurement module. Moreover, the measurement data is typically stable over time at a fixed location and can thus be replayed at later times. With this paper, we propose a system, which can provide functionality for a location proof, which does not rely on measurements and does not suffer from replay attacks. Therefore, a self-contained system is generating signed one-time passwords and communicates them via 2D barcodes for authentication of camera-enabled devices being in a specific location.

Matrix codes enable a coupling between virtual and physical worlds for ubiquitous computing applications. With this paper, we propose a technique, which can be used to increase the amount of information contained in a matrix barcode in a backward compatible way. This enables applications to fully utilize the wide spread of QR Codes or Data Matrix Codes for service discovery or basic service, while being able to transmit much more information during one scan for advanced applications. We present the approach, explain difficulties in decoding typical camera images, a simulatory evaluation of decoding performance, and application examples.

[BibTeX] [Abstract]

Context-aware computing has been an intensively researched topic for years already. Consequently, there exists a plethora of usage scenarios for context-aware applications as well as several approaches for the modeling and management of a user’s context information, many of which focus on the efficient and scalable distribution of the latter. With the ongoing rise of smartphones as everyday mobile devices and their steadily increasing amount of sensing and communication capabilities, we finally find ourselves at the edge towards a widespread usage of these techniques. However, apart from technical issues such as how to reliably determine a user’s current context, privacy still remains a crucial factor for these systems’ acceptance rate. Therefore, inspired by earlier works on privacy in context-aware computing and the authors’ beliefs in the necessity to put users in control, this paper presents a novel approach for modeling and managing a mobile user’s context information in a user-centric and privacy-preserving way. To this end, this work’s contribution is twofold: First, based on widely recognized requirements for privacy in context-aware applications, we propose a privacy-centric context model which allows for an intuitive and context-dependent definition of a user’s privacy preferences, directly integrating privacy aspects into the context model itself. Second, we present a generic and flexible architecture for the management and distribution of context information in a privacy-preserving way fit for a multitude of different usage scenarios.

[BibTeX] [Abstract]

This paper investigates a complication of the classical Traveling Salesman Problem, which arises due to multiple points of interest with functional equivalence. While the classical Traveling Salesman Problem tries to find a shortest tour visiting each point in a set exactly once, we consider the challenge of finding the shortest tour visiting each point of a given set exactly once and exactly one additional point out of a different set of equivalent places. The insertion of a gas station to a traveling salesman problem provides an example. With this paper, we investigate and analyze different algorithms to solve this complex problem by reducing it to the solution of a set of classic Traveling Salesman Problems. Furthermore, we provide an efficient tradeoff between the size of the set of traditional problems still to be solved and the expected error of the algorithm.

With the now widespread usage of increasingly powerful smartphones, pro-active, context-aware, and thereby unobstrusive applications have become possible. A user’s current activity is a primary piece of contextual information, and especially in urban areas, a user’s current mode of transport is an important part of her activity. A lot of research has been conducted on automatically recognizing different means of transport, but up to now, no attempt has been made to perform a fine-grained classification of different activities related to travelling by local public transport. In this work, we present an approach to recognize 17 different activities related to travelling by subway. We use only the sensor technology available in modern mobile phones and achieve a high classification accuracy of over 90%, without requiring a specific carrying position of the device. We discuss the usefulness of different sensors and computed features, and identify individual characteristics of the considered activities.

Online services, particularly those aimed at a specific user base such as a company’s employees, face the problem of identity management. Especially when the service constitutes some kind of social network, i.e., the validity of the users‘ identities matters, secure and reliable means for identity verification and authentication are required. In this paper, we propose a novel identity management concept based on a) verification through physical presence and b) authentication through ownership. Our approach being a hybrid solution between a centralized authority and decentralized trust management is settled on a sweet spot between security and convenience for the users.

[BibTeX] [Abstract] [Download PDF]

Interest dissemination in constrained environments such as wireless sensor networks utilizes Bloom filters commonly. A Bloom filter is a probabilistic data structure of fixed length, which can be used to encode the set of sensor nodes to be awake. In this way an application can disseminate interest in specific sensor nodes by broadcasting the Bloom filter throughout the complete wireless sensor network. The probabilistic nature of a Bloom filter induces false positives, that is some sensor nodes will be awake without the application having interest in their sensor values. As the interest is often depending on location such as in adaptive sampling applications, we present a novel method to encode both interest and possible location of information into one probabilistic data structure simultaneously. While our algorithm is able to encode any kind of tree-structured information into a fixed length bit array we exemplify its use through a wireless sensor network. In comparison to traditional Bloom encoding techniques we are able to reduce the overall number of false positives and furthermore reduce the average distance of false positives from the next true positive of the same interest. In our example this helps to reduce the overall energy consumption of the sensor network by only requesting sensor nodes that are likely to store the requested information.

[BibTeX] [Abstract]

By leveraging sensors embedded in mobile devices, participatory sensing tries to create large-scale sensing systems. One major challenge in these participatory sensing networks is the problem of distributing sensing tasks in an energy-efficient manner. A large portion of energy is typically consumed for the exchange of tasks between the tasking server and the mobile devices, as well as for the position monitoring needed to detect whether a user is situated within the tasking area. In this paper, we mainly focus on reducing energy for receiving and monitoring tasks on the client side. We propose an energy-efficient task distribution and monitoring concept for participatory sensing systems and evaluate it by means of simulation.

[BibTeX] [Abstract]

Mobile Edge Computing proposes co-locating computing and storage resources at base stations of cellular networks. It is seen as a promising technique to alleviate utilization of the mobile core and to reduce latency for mobile end users. Due to the fact that Mobile Edge Computing is a novel approach not yet deployed in real-life networks, recent work discusses merely general and non-technical ideas and concepts. This paper introduces a taxonomy for Mobile Edge Computing applications and analyzes chances and limitations from a technical point of view. Application types which profit from edge deployment are identified and discussed. Furthermore, these applications are systematically classified based on technical metrics.

[BibTeX] [Abstract]

With the ongoing rise of smartphones as everyday mobile devices and their steadily increasing amount of sensing and communication capabilities, we are on the brink of a subtle, widespread adoption of context-aware computing techniques into our daily lives. Focusing on functionality and performance, the majority of existing architectures for managing context information typically deploy central components for collecting, analyzing and distributing its users‘ up-to-date data. However, preservation of users‘ privacy needs remains a crucial factor for such systems‘ acceptableness. Inspired by existing works on privacy in context-aware applications and the authors‘ beliefs in the necessity to put users back in control, this article adopts a privacy-centric perspective and presents ALPACA: A novel approach for modeling and managing a user’s rich context information in a user-centric and privacy-preserving way fit for a multitude of different usage scenarios. To this end, this article offers a general conceptual mapping of a user’s privacy needs to distinct layers. Based on this conceptualization we introduce a privacy-centric approach for modeling this information. Additionally, we propose a context-aware mechanism for the definition of context-dependent release triggers in order to enable fine-grained control over the disclosure of sensitive information. Finally, we present the components of the proposed system architecture, explain how they interact with each other and discuss how our framework can be integrated into a modern mobile operating system.

Bitcoin has become increasingly important in recent years. The exchange rate raised from \$14 in January 2013 up to \$240 in April 2013 and even \$900 in early 2014. In this paper, we present novel insights about Bitcoin’s peer-to-peer (P2P) network with a special focus on its distribution among distinct autonomous systems. We traversed Bitcoin’s P2P network in a protocol-compliant manner and collected information about the network size, the number of clients, and the network distribution among autonomous systems. Our findings lead to conclusions about the resilience of the Bitcoin ecosystem, the unambiguousness of the blockchain in use, and the propagation and verification of transaction blocks.

[BibTeX] [Abstract]

With this paper, we propose a novel semantic compression scheme for GPS trajectories which exploits map knowledge for data reduction. Therefore, the compression is integrated into a simple map matching scheme and shows superior performance with respect to the compression ratio. In contrast to other compression schemes including compressed GPX files, a lot of information about a trajectory can be readily extracted from the given representation and a uniformly sampled representative can be easily calculated for advanced trajectory comparison. We provide a detailed analysis of the approach as well as preliminary results on performance and feasibility of this approach in typical urban mobility scenarios.

The increasing spread of high-capacity sensor-equipped mobile devices provides new possibilities for scientific ambit. Many possible applications have been made accessible in the recent past. In this paper, the benefit of mobile sensing data collection for science is presented, using as example the combination of algorithmic weather forecasting and user contributed observations associated with participatory sensing. The newly developed DLR winter weather nowcasting system WHITE for the Munich airport intends a close cooperation with users and it utilizes data collected by mobile devices for validation. For these purposes, a mobile web application has been developed and operated during a campaign in the winter of 2012/2013. The technical structure of the application and its performance during the campaign as well as the main features of the WHITE system are the basic components of this paper.

Online services, particularly those aimed at a specific user base such as a company’s employees, face the problem of identity management. Especially when the service constitutes some kind of social network, i.e., the validity of the users‘ identities matters, secure and reliable means for identity verification and authentication are required. In this paper, predicated on our previous work, we propose an identity management concept based on a) verification through physical presence and b) authentication through ownership. Our approach being a hybrid solution between a centralized authority and decentralized trust management is settled on a sweet spot between security and convenience for the users. In this extended version, we present the newly proposed Tree of Trust structure in more detail, and provide a thourough explanation how the system can be used in a technically more distributed manner, even supporting offline operation.

[BibTeX] [Abstract]

Due to the increasing popularity of location-based services, the need for reliable and cost-effective indoor positioning methods is rising. As an alternative to radio-based localization methods, in 2011, we introduced MoVIPS (Mobile Visual Indoor Positioning System), which is based on the idea to extract visual feature points from a query image and compare them to those of previously collected geo-referenced images. The general feasibility of positioning by SURF points on a conventional smartphone was already shown in our previous work. However, the system still faced several shortcomings concerning real-world usage such as request times being too high and distance estimation being unreliable because of the employed estimation method not being rotation invariant. In this paper, three extensions are presented that improve the practical applicability of MoVIPS. To speed up request times, both a dead reckoning approach (based on step counting using the accelerometer) and an orientation estimation (based on the smartphone’s compass) are introduced to filter relevant images from the database and thus to reduce the amount of images to compare the query image to. Furthermore, the vectors of the SURF points are quantized. For this purpose, clusters are calculated from all SURF points from the database. As a result, each image can be represented by a histogram of cluster frequencies, which can be compared with each other a lot more efficiently. The third extension is an improvement of the distance estimation method, which uses the matched feature points of an image to perform a perspective transformation and to determine the actual position with the aid of the transformation matrix. Employing the first extension, request times are reduced by 84\% percent. The quantization of the SURF points reduces the search time by a factor of 1000. Finally, the distance estimation is now rotation invariant and enables a better position correction.

[BibTeX] [Abstract] [Download PDF]

Due to the rise of mobile computing and smartphones, a lot of information about groups has become accessible. This information shall often be kept secret. Hence distributed algorithms for privacy-preserving distribution estimation are needed. Most research currently focuses on privacy in a database, where a single entity has collected the secret information and privacy is ensured between query results and the database. In fully distributed systems such as sensor networks it is often infeasible to move the data towards a central entity for processing. Instead, distributed algorithms are needed. With this paper we propose a fully distributed, privacy-friendly, consensus-based approach. In our approach all nodes cooperate to generate a sufficiently random obfuscation of their secret values until the estimated and obfuscated values of the individual nodes can be safely published. Then the calculations can be done on this replacement containing only non-secret values but recovering some aspects (mean, standard deviation) of the original distribution.

M. Werner and S. Feld, „Homotopy and Alternative Routes in Indoor Navigation Scenarios,“ in 5th International Conference on Indoor Positioning and Indoor Navigation (IPIN 2014), 2014, pp. 230-238.
[BibTeX] [Abstract]

There are lots of innovative use cases possible that build on a shortest route between two locations together with a set of alternatives that are highly different yet short. Imagine, for example, a complicated building like an airport, where passengers can consult a computer terminal to get navigation advices to a desired goal. By scanning the boarding card the calculation of alternatives can be made context-sensitive. Based on gender, amount of time, or shopping preferences, for example, the terminal can display different routes regarding floors traversed, or shops and restaurants passed. Furthermore, the building operator can control the presentation of alternatives in order to influence visitor flows in real time. Therefore, we propose to use the topological concept of homotopy in order to decide if two routes should be considered equivalent or alternative. Basically, the homotopy relation identifies equivalence classes. We propose that a representative of an equivalence class is an alternative regarding another equivalence class. We concatenate the two routes in question and thus, create a polygon. If there is an obstacle inside, the routes are non-homotopic and we consider them as proper alternatives. For this situation, we propose two fundamentally different approaches that are able to find alternative routes with respect to homotopy. The input is a building plan in form of an occupancy grid.

abstract = {There are lots of innovative use cases possible that build on a shortest route between two locations together with a set of alternatives that are highly different yet short. Imagine, for example, a complicated building like an airport, where passengers can consult a computer terminal to get navigation advices to a desired goal. By scanning the boarding card the calculation of alternatives can be made context-sensitive. Based on gender, amount of time, or shopping preferences, for example, the terminal can display different routes regarding floors traversed, or shops and restaurants passed. Furthermore, the building operator can control the presentation of alternatives in order to influence visitor flows in real time. Therefore, we propose to use the topological concept of homotopy in order to decide if two routes should be considered equivalent or alternative. Basically, the homotopy relation identifies equivalence classes. We propose that a representative of an equivalence class is an alternative regarding another equivalence class.

[BibTeX] [Abstract]

Participatory sensing tries to create cost-effective, large-scale sensing systems by leveraging sensors embedded in mobile devices. One major challenge in these systems is to protect the users‘ privacy, since users will not contribute data if their privacy is jeopardized. Especially location data needs to be protected if it is likely to reveal information about the users‘ identities. A common solution is the blinding out approach that creates so-called ban zones in which location data is not published. Thereby, a user’s important places, e.g., her home or workplace, can be concealed. However, ban zones of a fixed size are not able to guarantee any particular level of privacy. For instance, a ban zone that is large enough to conceal a user’s home in a large city might be too small in a less populated area. For this reason, we propose an approach for dynamic map-based blinding out: The boundaries of our privacy zones, called Silent Zones, are determined in such way that at least k buildings are located within this zone. Thus, our approach adapts to the habitat density and we can guarantee k-anonymity in terms of surrounding buildings. In this paper, we present two new algorithms for creating Silent Zones and evaluate their performance. Our results show that especially in worst case scenarios, i.e., in sparsely populated areas, our approach outperforms standard ban zones and guarantees the specified privacy level.

Encoding multimedia streams of video calls is a very compute-intense task that significantly decreases battery lifetime of mobile phones. This paper introduces an approach to reduce power consumption of mobile phones by offloading video encoding efforts from mobile devices to external services. These services are hosted on servers co-located with cellular base stations. The paper describes how these services are integrated into the existing mobile network architecture and presents a communication protocol for negotiating offloading settings. First measurement results indicate that power consumption of mobile devices is reduced by approximately 13\%.

[BibTeX] [Abstract]

Currently navigation in indoor scenarios enjoys a highly increasing popularity. Besides that, there are numerous applications that utilize alternatives to a particular path. Think of a navigation system that proposes a mall’s visitor three different routes: the fastest, a route passing restaurants, and a route traversing shops. Thus, the visitor is able to choose a route by personal preference or experience. Further users of alternative routes can be fire fighters, mobile robots, or nonplayer characters in video games. In contrast to navigation in road networks, there are several challenges to solve in indoor scenarios. First, the creation of alternative routes is not much discussed in literature. Second, due to the high degree of freedom there is a large number of alternative routes possible regarding a reference path. Third, there is no proper understanding of how to measure the meaningfulness or quality of an alternative route. This paper is a step towards the evaluation of alternative routes in indoor navigation scenarios and has got two main contributions. First, we propose to use the term congestion probability as a first common understanding to estimate the meaningfulness of alternative routes inside buildings. Most of the indoor use cases are looking for routes that either seek or avoid crowded areas – at least as one of multiple criteria. Additionally, we propose to score alternative routes based on a local and a global perception. The paper’s second contribution is an algorithm that scores a set of alternative routes based on an ordinary floor plan. Thus, it compares a formerly non-valuated set of routes and creates a ranking regarding the congestion probability. Basically, the algorithm is based on the assumption that points on a map, that are frequently located on shortest paths, will also be frequently traversed. Due to the lack of appropriate data sets we discuss the algorithm’s results in detail by means of four different indoor scenarios.

[BibTeX] [Abstract]

Alternative routes have found many applications in navigation scenarios. However, alternative routes have only been introduced recently for the indoor space due to the complexity of these environments. Furthermore, the number of alternative routes in buildings can be quite high. With this paper, we propose to organize sets of alternative routes by employing archetypal analysis on a feature space representation of routes and show results in which a set of hundreds of routes between the same start and end point has been compressed to only a few obviously different archetypal routes. Additionally, the framework allows for comparing routes with archetypes and with each other. This comparison does not reveal spatial similarity alone, but rather a measure of routes‘ similarity representing their inherent semantic character.

[BibTeX] [Abstract]

The knowledge of future Signal Phase and Timing information (SPaT) of traffic lights ahead enables a vast number of driving assistance functions, such as Green Light Optimal Speed Control (GLOSA), Red Light Duration Advisory (RLDA) or Traffic Signal Adaptive routing (TSA routing). The purpose of TSA routing is to reduce the travel time by choosing a route that is possibly longer than the shortest one but has less red lights. Whereas GLOSA and RLDA are quite easy to implement from a scientific point of view, TSA routing presents a certain challenge: first of all, TSA routing necessitates predictions on future signal states on a wider look in the future than GLOSA and RLDA, a possible reason why this field of research still seems rather unexplored. Second, there are still many unresolved issues, such as the inadequacy of graphs for TSA-routing, or proper traffic load estimations. In this paper, we present a fully functioning model for TSA routing on the basis of our forgoing research on the prediction of future signal states and address the question of practical usability by evaluating our model under realistic conditions. We analyze, among other things, the impact of partial knowledge on traffic light’s future signal states and the impact of different traffic loads on TSA routes by means of a test field in Munich, Germany. We describe necessary modifications of the underlying transportation network’s graph structure and shortest path routing algorithm to allow routing under consideration of future signal states of traffic lights. We show that, albeit there are many erratic aspects in traffic and signal states, TSA routing still reaches a significant travel time gain over usual routing in our test field.

[BibTeX] [Abstract] [Download PDF]

Bitcoin has become increasingly important for several years. While being declared dead in the meantime, it got a boost in 2011. The exchange rate increased from \$14 in January 2013 up to \$240 in April 2013 and even \$900 in early 2014. Lots of existing work addresses the analysis of the publicly available transaction graph. There are evaluations of the user’s anonymity and privacy, but no proper measurements of the underlying network. In this paper, we present novel insights about Bitcoin’s peer-to-peer network, with a focus on its distribution among distinct autonomous systems. The resilience of the Bitcoin ecosystem, the unambiguousness of the blockchain in use, the propagation and verification of transaction blocks, but also the anonymity of Bitcoin’s users depend on the structure of the global peer-to-peer network. Our work is the first thorough analysis of Bitcoin’s underlying peer-to-peer network, especially with regard to its distribution at the autonomous system level. We traversed Bitcoin’s peer-to-peer network in a protocol-compliant manner and made statements about the size of the accessible network and the number of clients. This information is useful when modelling the probability of attacks against the user’s privacy or other aspects. Further, we investigated the distribution of the peer-to-peer network on autonomous systems. The concrete form has an impact on the above-mentioned topics, such as vitality, resilience or privacy. Finally, we analysed the mechanism to announce known peers. It turns out that Bitcoin’s peer announcement is not well distributed, affecting information propagation.

[BibTeX] [Abstract]

One critical prerequisite for the deployment of reinforcement learning systems in the real world is the ability to reliably detect situations on which the agent was not trained. Such situations could lead to potential safety risks when wrong predictions lead to the execution of harmful actions. In this work, we propose PEOC, a new policy entropy based out-of-distribution classifier that reliably detects unencountered states in deep reinforcement learning. It is based on using the entropy of an agent’s policy as the classification score of a one-class classifier. We evaluate our approach using a procedural environment generator. Results show that PEOC is highly competitive against state-of-the-art one-class classification algorithms on the evaluated environments. Furthermore, we present a structured process for benchmarking out-of-distribution classification in reinforcement learning.

[BibTeX] [Abstract] [Download PDF]

This paper applies reinforcement learning to train a predator to hunt multiple prey, which are able to reproduce, in a 2D simulation. It is shown that, using methods of curriculum learning, long-term reward discounting and stacked observations, a reinforcement-learning-based predator can achieve an economic strategy: Only hunt when there is still prey left to reproduce in order to maintain the population. Hence, purely selfish goals are sufficient to motivate a reinforcement learning agent for long-term planning and keeping a certain balance with its environment by not depleting its resources. While a comparably simple reinforcement learning algorithm achieves such behavior in the present scenario, providing a suitable amount of past and predictive information turns out to be crucial for the training success.

[BibTeX] [Abstract] [Download PDF]

This paper considers sustainable and cooperative behavior in multi-agent systems. In the proposed predator-prey simulation, multiple selfish predators can learn to act sustainably by maintaining a herd of reproducing prey and further hunt cooperatively for long term benefit. Since the predators face starvation pressure, the scenario can also turn in a tragedy of the commons if selfish individuals decide to greedily hunt down the prey population before their conspecifics do, ultimately leading to extinction of prey and predators. This paper uses Multi-Agent Reinforcement Learning to overcome a collapse of the simulated ecosystem, analyzes the impact factors over multiple dimensions and proposes suitable metrics. We show that up to three predators are able to learn sustainable behavior in form of collective herding under starvation pressure. Complex cooperation in form of group hunting emerges between the predators as their speed is handicapped and the prey is given more degrees of freedom to escape. The implementation of environment and reinforcement learning pipeline is available online.

A characteristic of reinforcement learning is the ability to develop unforeseen strategies when solving problems. While such strategies sometimes yield superior performance, they may also result in undesired or even dangerous behavior. In industrial scenarios, a system’s behavior also needs to be predictable and lie within defined ranges. To enable the agents to learn (how) to align with a given specification, this paper proposes to explicitly transfer functional and non-functional requirements into shaped rewards. Experiments are carried out on the smart factory, a multi-agent environment modeling an industrial lot-size-one production facility, with up to eight agents and different multi-agent reinforcement learning algorithms. Results indicate that compliance with functional and non-functional constraints can be achieved by the proposed approach.

Based on the quantum-assisted genetic algorithm (QAGA) [11] and related approaches we introduce several modifications of QAGA to search for more promising solvers on (at least) graph coloring problems, knapsack problems, Boolean satisfiability problems, and an equal combination of these three. We empirically test the efficiency of these algorithmic changes on a purely classical version of the algorithm (simulated-annealing-assisted genetic algorithm, SAGA) and verify the benefit of selected modifications when using quantum annealing hardware. Our results point towards an inherent benefit of a simpler and more flexible algorithm design.

State preparation is currently the only means to provide input data for quantum algorithm, but finding the shortest possible sequence of gates to prepare a given state is not trivial. We approach this problem using reinforcement learning (RL), first on an agent that is trained to only prepare a single fixed quantum state. Despite the overhead of training a whole network to just produce one single data point, gradient-based backpropagation appears competitive to genetic algorithms in this scenario and single state preparation thus seems a worthwhile task. In a second case we then train a single network to prepare arbitrary quantum states to some degree of success, despite a complete lack of structure in the training data set. In both cases we find that training is severely improved by using QR decomposition to automatically map the agents‘ outputs to unitary operators to solve the problem of sparse rewards that usually makes this task challenging.

The development of Machine Learning (ML) models is more than just a special case of software development (SD): ML models acquire properties and fulfill requirements even without direct human interaction in a seemingly uncontrollable manner. Nonetheless, the underlying processes can be described in a formal way. We define a comprehensive SD process model for ML that encompasses most tasks and artifacts described in the literature in a consistent way. In addition to the production of the necessary artifacts, we also focus on generating and validating fitting descriptions in the form of specifications. We stress the importance of further evolving the ML model throughout its life-cycle even after initial training and testing. Thus, we provide various interaction points with standard SD processes in which ML often is an encapsulated task. Further, our SD process model allows to formulate ML as a (meta-) optimization problem. If automated rigorously, it can be used to realize self-adaptive autonomous systems. Finally, our SD process model features a description of time that allows to reason about the progress within ML development processes. This might lead to further applications of formal methods within the field of ML.

[BibTeX] [Abstract]

Engineering intelligent industrial systems is challenging due to high complexity and uncertainty with respect to domain dynamics and multiple agents. If industrial systems act autonomously, their choices and results must be within specified bounds to satisfy these requirements. Reinforcement learning (RL) is promising to find solutions that outperform known or handcrafted heuristics. However in industrial scenarios, it also is crucial to prevent RL from inducing potentially undesired or even dangerous behavior. This paper considers specification alignment in industrial scenarios with multi-agent reinforcement learning (MARL). We propose to embed functional and non-functional requirements into the reward function, enabling the agents to learn to align with the specification. We evaluate our approach in a smart factory simulation representing an industrial lot-size-one production facility, where we train up to eight agents using DQN, VDN, and QMIX. Our results show that the proposed approach enables agents to satisfy a given set of requirements.

{A key element of biological structures is self-replication. Neural networks are the prime structure used for the emergent construction of complex behavior in computers. We analyze how various network types lend themselves to self-replication. Backpropagation turns out to be the natural way to navigate the space of network weights and allows non-trivial self-replicators to arise naturally. We perform an in-depth analysis to show the self-replicatorsâ€™ robustness to noise. We then introduce artificial chemistry environments consisting of several neural networks and examine their emergent behavior. In extension to this works previous version (Gabor et al., 2019), we provide an extensive analysis of the occurrence of fixpoint weight configurations within the weight space and an approximation of their respective attractor basins.}
