Abstract

In autonomous driving, accurate motion prediction is essential for safe and efficient motion planning. To ensure safety, planners must rely on reliable uncertainty information about the predicted future behavior of surrounding agents, yet this aspect has received limited attention. This paper addresses the so-far neglected problem of uncertainty modeling in trajectory prediction. We adopt a holistic approach that focuses on uncertainty quantification, decomposition, and the influence of model composition. Our method is based on a theoretically grounded information-theoretic approach to measure uncertainty, allowing us to decompose total uncertainty into its aleatoric and epistemic components. We conduct extensive experiments on the nuScenes dataset to assess how different model architectures and configurations affect uncertainty quantification and model robustness., Comment: 10 pages, 5 figures, submitted to International Conference on Learning Representations (2025)

Abstract

In autonomous driving tasks, scene understanding is the first step towards predicting the future behavior of the surrounding traffic participants. Yet, how to represent a given scene and extract its features are still open research questions. In this study, we propose a novel text-based representation of traffic scenes and process it with a pre-trained language encoder. First, we show that text-based representations, combined with classical rasterized image representations, lead to descriptive scene embeddings. Second, we benchmark our predictions on the nuScenes dataset and show significant improvements compared to baselines. Third, we show in an ablation study that a joint encoder of text and rasterized images outperforms the individual encoders confirming that both representations have their complementary strengths.

Abstract

Automated vehicles require a comprehensive understanding of traffic situations to ensure safe and anticipatory driving. In this context, the prediction of pedestrians is particularly challenging as pedestrian behavior can be influenced by multiple factors. In this paper, we thoroughly analyze the requirements on pedestrian behavior prediction for automated driving via a system-level approach. To this end we investigate real-world pedestrian-vehicle interactions with human drivers. Based on human driving behavior we then derive appropriate reaction patterns of an automated vehicle and determine requirements for the prediction of pedestrians. This includes a novel metric tailored to measure prediction performance from a system-level perspective. The proposed metric is evaluated on a large-scale dataset comprising thousands of real-world pedestrian-vehicle interactions. We furthermore conduct an ablation study to evaluate the importance of different contextual cues and compare these results to ones obtained using established performance metrics for pedestrian prediction. Our results highlight the importance of a system-level approach to pedestrian behavior prediction., Comment: This work has been submitted to the IEEE Transactions on Intelligent Transportation Systems for possible publication.

Abstract

To verify and validate networks, it is essential to gain insight into their decisions, limitations as well as possible shortcomings of training data. In this work, we propose a post-hoc, optimization based visual explanation method, which highlights the evidence in the input image for a specific prediction. Our approach is based on a novel technique to defend against adversarial evidence (i.e. faulty evidence due to artefacts) by filtering gradients during optimization. The defense does not depend on human-tuned parameters. It enables explanations which are both fine-grained and preserve the characteristics of images, such as edges and colors. The explanations are interpretable, suited for visualizing detailed evidence and can be tested as they are valid model inputs. We qualitatively and quantitatively evaluate our approach on a multitude of models and datasets., Comment: In Proceedings of IEEE Conference on Computer Vision and Pattern Recognition (CVPR), Long Beach, CA, USA, June 2019

Abstract

Imitation Learning describes the problem of recovering an expert policy from demonstrations. While inverse reinforcement learning approaches are known to be very sample-efficient in terms of expert demonstrations, they usually require problem-dependent reward functions or a (task-)specific reward-function regularization. In this paper, we show a natural connection between inverse reinforcement learning approaches and Optimal Transport, that enables more general reward functions with desirable properties (e.g., smoothness). Based on our observation, we propose a novel approach called Wasserstein Adversarial Imitation Learning. Our approach considers the Kantorovich potentials as a reward function and further leverages regularized optimal transport to enable large-scale applications. In several robotic experiments, our approach outperforms the baselines in terms of average cumulative rewards and shows a significant improvement in sample-efficiency, by requiring just one expert demonstration.

Abstract

The performance of autonomous systems heavily relies on their ability to generate a robust representation of the environment. Deep neural networks have greatly improved vision-based perception systems but still fail in challenging situations, e.g. sensor outages or heavy weather. These failures are often introduced by data-inherent perturbations, which significantly reduce the information provided to the perception system. We propose a functionally modularized temporal filter, which stabilizes an abstract feature representation of a single-frame segmentation model using information of previous time steps. Our filter module splits the filter task into multiple less complex and more interpretable subtasks. The basic structure of the filter is inspired by a Bayes estimator consisting of a prediction and an update step. To make the prediction more transparent, we implement it using a geometric projection and estimate its parameters. This additionally enables the decomposition of the filter task into static representation filtering and low-dimensional motion filtering. Our model can cope with missing frames and is trainable in an end-to-end fashion. Using photorealistic, synthetic video data, we show the ability of the proposed architecture to overcome data-inherent perturbations. The experiments especially highlight advantages introduced by an interpretable and explicit filter module., Comment: In Proceedings of 29th British Machine Vision Conference (BMVC), Newcastle upon Tyne, UK, 2018

Abstract

Generating a robust representation of the environment is a crucial ability of learning agents. Deep learning based methods have greatly improved perception systems but still fail in challenging situations. These failures are often not solvable on the basis of a single image. In this work, we present a parameter-efficient temporal filtering concept which extends an existing single-frame segmentation model to work with multiple frames. The resulting recurrent architecture temporally filters representations on all abstraction levels in a hierarchical manner, while decoupling temporal dependencies from scene representation. Using a synthetic dataset, we show the ability of our model to cope with data perturbations and highlight the importance of recurrent and hierarchical filtering., Comment: In Proceedings of 26th European Symposium on Artificial Neural Networks, Computational Intelligence and Machine Learning (ESANN), Bruges, Belgium, 2018

Abstract

The fundamental principle of integrated motion measurement (IMM) is integrated navigation with inertial sensors combined with, for example, a satellite navigation receiver. Accordingly, IMM makes use of the specific advantages of complementary sensors and blends them in a filter algorithm. To meet requirements in advanced motion measurements, for instance, for structural health monitoring or for structural control purposes, the approach of a single rigid body like in classical navigation no longer holds for IMM. As a solution, additional degrees of freedom (DOFs) for the moving structure are introduced, which represent deformations and allow the navigated body to be treated as a flexible structure. To cover a variety of flexible deformation shapes, a sufficient number of distributed inertial sensors is required. To restrict accumulating errors of these sensors, additional structural measurements for aiding are necessary. The signals of the inertial sensors and the aiding measurements are fused by an extended Kalman filter (EKF) to obtain an optimal estimation of the usual navigation states, extended by the deformation variables. The contribution presents the preparation of the experimental validation of an IMM system for a flexible structure, which represents an idealization of a wing or rotor blade by a movable beam. The mechanical and electrical setup of a test rig is described. Furthermore, the simulation of the test configuration, that is the model of a test beam with a variety of distributed sensors for generating artificial measurements as a test reference, is discussed. Finally, for an optimal sensor placement, the two methods of effective independence and maximization of modal energy are compared and experimentally tested for different amounts of additional flexible DOFs.

Abstract

Inverse Reinforcement Learning (IRL) describes the problem of learning an unknown reward function of a Markov Decision Process (MDP) from observed behavior of an agent. Since the agent's behavior originates in its policy and MDP policies depend on both the stochastic system dynamics as well as the reward function, the solution of the inverse problem is significantly influenced by both. Current IRL approaches assume that if the transition model is unknown, additional samples from the system's dynamics are accessible, or the observed behavior provides enough samples of the system's dynamics to solve the inverse problem accurately. These assumptions are often not satisfied. To overcome this, we present a gradient-based IRL approach that simultaneously estimates the system's dynamics. By solving the combined optimization problem, our approach takes into account the bias of the demonstrations, which stems from the generating policy. The evaluation on a synthetic MDP and a transfer learning task shows improvements regarding the sample efficiency as well as the accuracy of the estimated reward functions and transition models., Comment: accepted to appear in AISTATS 2016

Abstract

The article "Effects of the lack of a hearing before the confiscation of a dog" deals with a case in which an applicant challenges animal welfare measures taken by the district office of Rems-Murr-Kreis. After his application for interim legal protection was rejected, his appeal was partially successful. It is discussed that the confiscation of animals without prior hearing is not justified and that the restoration of the suspensive effect of the applicant's objection was ordered. It is emphasized that a hearing before the issuance of an administrative act according to § 28 para. 1 LVwVfG is necessary and that an applicant is entitled to the return of his dogs that were previously taken away.

Abstract

The article describes a case before the Administrative Court of Düsseldorf, in which a vehicle was towed from a car-sharing parking lot. The plaintiff filed a lawsuit against the performance and fee notice but was dismissed. The court ruled that the towing was lawful because there was a violation of the Road Traffic Regulations and a danger to public safety. The costs of towing were imposed on the plaintiff. The traffic authorities are not obliged to continuously check the need for parking spaces to be kept free. Towing such vehicles is justified as it has a negative deterrent effect. The administrative fee set for towing is lawful and reasonable. [Extracted from the article]

Abstract

The article "Police incapacity after a spinal disc implantation" deals with the case of a female police officer who was classified as unfit for police service after a spinal disc prosthesis. The police doctor determined that the officer had permanent limitations in her ability to perform certain tasks and had to avoid certain risks. Despite a medical certificate stating that the officer had been free of complaints for a year and was fit for duty again, she was classified as unfit for police service. The Higher Administrative Court of Berlin-Brandenburg has identified similar risks in a female police officer with a spinal disc prosthesis. The submitted medical certificates and specialist opinions were evaluated by the police doctor and confirm the risk assessment. The certificate from a doctor in the American military service is not relevant for determining police fitness. [Extracted from the article]

The police ordered the seizure of the vehicle and charged the plaintiff fees and expenses. The court ruled that the seizure order was unlawful and that the plaintiff was wrongly charged. The traffic sign indicating a parking ban for non-electric vehicles has no legal effect because it is not located in an area where parking is only allowed for electric vehicles. The appellate court rejected the argument that the parking ban could also be extended to the parking spaces immediately to the left and right of the traffic sign. [Extracted from the article]

Abstract

Kurt Magnus (1912–2003) is one of the personalities who shaped research and teaching in applied mechanics during the 20th century. Through his work with his doctoral supervisor Max Schuler at the University of Göttingen, gyrodynamics became his most important field of work, which also led to his research in oscillations, multi‐body systems, and mechatronics. Magnus made significant contributions in all these fields. He was regarded as a gifted lecturer, and the close connection between scientific research and practical application was important to him. Life and scientific work of Kurt Magnus were, however, also characterized by his 7‐year deportation to the USSR in 1946. Despite this fate, he was able to continue his research under certain restrictions during this time. After returning to Germany, he became Professor of Mechanics at the University of Stuttgart in 1958. His appointment coincided with the gradual resumption of industrial activities in Germany in the field of gyro technology—activities that had come to a standstill at the end of World War II. In the years that followed, Magnus' institute became the scientific center for gyrodynamics in Germany. The activities of that time are reflected in a preserved collection of gyro instruments for research and teaching as well as in the co‐founding of an annual international conference on inertial technology, which continues to this day. Magnus' subsequent move to the Technical University of Munich in 1966 did nothing to change this. At that time, he was regarded as a doyen of gyro technology. After a short biography of Kurt Magnus, the paper addresses the recent revision and digitization of the gyro instrument collection and presents an outline of the history of the conference series providing details on how gyro technology has developed since his work in Stuttgart.

27. On the Distortion of the Eigenvalue Spectrum in MIMO Amplify-and-Forward Multi-Hop Channels

Abstract

Consider a wireless MIMO multi-hop channel with n_s non-cooperating source antennas and n_d fully cooperating destination antennas, as well as L clusters containing k non-cooperating relay antennas each. The source signal traverses all L clusters of relay antennas, before it reaches the destination. When relay antennas within the same cluster scale their received signals by the same constant before the retransmission, the equivalent channel matrix H relating the input signals at the source antennas to the output signals at the destination antennas is proportional to the product of channel matrices H_l, l=1,...,L+1, corresponding to the individual hops. We perform an asymptotic capacity analysis for this channel as follows: In a first instance we take the limits n_s->infty, n_d->infty and k->infty, but keep both n_s/n_d and k/n_d fixed. Then, we take the limits L->infty and k/n_d->infty. Requiring that the H_l's satisfy the conditions needed for the Marcenko-Pastur law, we prove that the capacity scales linearly in min{n_s,n_d}, as long as the ratio k/n_d scales at least linearly in L. Moreover, we show that up to a noise penalty and a pre-log factor the capacity of a point-to-point MIMO channel is approached, when this scaling is slightly faster than linear. Conversely, almost all spatial degrees of freedom vanish for less than linear scaling., Comment: submitted to Eurasip Journal on Wireless Communications and Networking

28. Large N Analysis of Amplify-and-Forward MIMO Relay Channels with Correlated Rayleigh Fading

Abstract

In this correspondence the cumulants of the mutual information of the flat Rayleigh fading amplify-and-forward MIMO relay channel without direct link between source and destination are derived in the large array limit. The analysis is based on the replica trick and covers both spatially independent and correlated fading in the first and the second hop, while beamforming at all terminals is restricted to deterministic weight matrices. Expressions for mean and variance of the mutual information are obtained. Their parameters are determined by a nonlinear equation system. All higher cumulants are shown to vanish as the number of antennas n goes to infinity. In conclusion the distribution of the mutual information I becomes Gaussian in the large n limit and is completely characterized by the expressions obtained for mean and variance of I. Comparisons with simulation results show that the asymptotic results serve as excellent approximations for systems with only few antennas at each node. The derivation of the results follows the technique formalized by Moustakas et al. in [1]. Although the evaluations are more involved for the MIMO relay channel compared to point-to-point MIMO channels, the structure of the results is surprisingly simple again. In particular an elegant formula for the mean of the mutual information is obtained, i.e., the ergodic capacity of the two-hop amplify-and-forward MIMO relay channel without direct link., Comment: submitted for publication to IEEE Transactions on Information Theory

Abstract

The article deals with a case in which a plaintiff challenges the costs of a seizure that were imposed on him after he refused to undergo a drug test. During a traffic control, the plaintiff was stopped and the police ordered a breathalyzer test and a drug test. The plaintiff refused the drug test and a blood sample was ordered, which revealed the presence of THC in the plaintiff's blood. The plaintiff objected to the costs of the seizure and storage of his car keys and driver's license, but the objection was rejected and the plaintiff's lawsuit was also dismissed. The article explains the legal basis for police intervention in alleged dangerous situations and discusses the costs that can be imposed on the responsible party if it turns out afterwards that there was no danger. It is argued that in this case, the plaintiff should bear the costs since he caused the alleged danger through his behavior. [Extracted from the article]

The article "State liability for a fallen traffic sign" is about a lawsuit against the defendant due to a fallen road sign. The plaintiff, a car dealership, had parked their vehicle in front of their premises when the sign fell onto the car and damaged it. The plaintiff is demanding compensation for repair costs, expert fees, and attorney fees. The district court dismissed the lawsuit, but the regional court allowed for an appeal. The Federal Court of Justice ruled that the employees of the defendant, who had installed the sign, acted as administrative assistants and therefore cannot be held personally liable. It is emphasized that the sovereign nature of the entire measure is the focus, not just the individual activity that caused the damage. It is also noted that the private company had no relevant decision-making authority. [Extracted from the article]

Abstract

The article deals with the immediate enforcement of the revocation of a driver's license after cycling under the influence. An applicant had lost his driver's license due to cycling under the influence with a blood alcohol content of 2.35 ‰. The administrative court overturned the decision of the district office, but the Free State of Bavaria filed an appeal. The applicant filed a motion to amend the decision and restore the suspensive effect of the lawsuit, which was rejected because the appeal is likely to be successful. According to § 13 sentence 1 no. 2 letter c of the Driver's License Regulation (FeV), the driver's license authority can order the submission of a medical-psychological assessment if the driver's license holder has operated a vehicle in road traffic under the influence of alcohol, including bicycles. The driver's license authority can assess the need for an assessment independently of criminal prosecution, but this must be sufficiently documented. [Extracted from the article]

Abstract

The article deals with the usability of old entries for the revocation of a driver's license based on the fitness assessment system. The Federal Administrative Court decided that decisions stored in the Central Traffic Register before April 30, 2014 could no longer be used to calculate the point score. Before May 1, 2014, point scores of 8 to 10 points corresponded to a score of 4 points under the new assessment system. The usability of entries in the fitness register is governed by § 29 (7) sentence 1 of the Road Traffic Act and may no longer be used to the detriment of the person concerned after deletion. The extension of the usability of old entries has an indirect retroactive effect on the plaintiff, which is not objectionable under constitutional law. The change in the law aims to strengthen road safety and exclude unsuitable driver's license holders from driving motor vehicles. [Extracted from the article]

The document titled "Reversing in the one-way street against the prescribed direction of travel is not permitted" is about a traffic accident in which a plaintiff sues the defendants for compensation for further material damage. The plaintiff had parked his vehicle forward in a driveway located on a one-way street. The defendant drove past the driveway in the direction of the one-way street. When the plaintiff reversed into the one-way street to collide with the defendant, the defendant reversed a few meters to make room for a vehicle pulling out. The court ruled that reversing in the one-way street against the prescribed direction of travel is not permitted. The lawsuit was partially decided in favor of the plaintiff, and the case is referred back to the appellate court for a new trial. [Extracted from the article]

Abstract

The article is about a request for a court-imposed deadline due to an administrative disciplinary procedure that has not been concluded within six months. The applicant was working as a class leader at the training seminar of the riot police department but was suspended due to complaints from colleagues, leading to the initiation of a disciplinary procedure. However, the Administrative Court of Munich rejected the request as there is no undue delay and the investigations were conducted appropriately. It is a complex procedure that required extensive investigations. The request for the conclusion of the procedure is denied as there are sufficient reasons for the pending completion of the process.

Abstract

The present text deals with the legal assessment of an eviction from an apartment and a ban on return by the police. It is determined that the measures are unlawful because the conditions for such a measure were not met. The police did not have sufficient evidence of a present danger posed by the plaintiff and should have confronted him with the statements of his wife. It is also determined that the incident with the open kitchen cabinet door is not sufficient to justify an act of violence. The question of a possible error of discretion is not conclusively answered. [Extracted from the article]

Abstract

The article is about a case in traffic law where an applicant lost his driving license due to doubts about his suitability. The driving license authority requested a medical-psychological assessment because the applicant was cycling under the influence of alcohol. The applicant lodged an objection against this order, but it is expected that the objection will be unsuccessful. The authority considers the request for an assessment to be lawful, as participating in road traffic while intoxicated poses a danger to traffic safety, regardless of whether a motor vehicle or a bicycle is used. The blood sample taken from the applicant may be used in the driving license revocation procedure, despite a violation of the Code of Criminal Procedure. The termination of the criminal investigation proceedings for drunk driving due to the fulfillment of a condition does not affect the decision of the driving license authority.

Abstract

The article deals with the imposition of a logbook requirement for the entire fleet of a company. The applicant has filed a lawsuit against this order, but was rejected. The order is based on traffic violations where the driver could not be identified. The administrative court has decided that the expansion of the logbook requirement to the entire fleet is justified, as several violations have been committed with different company vehicles and further violations are expected in the future. The applicant could not provide sufficient reasons to exclude individual vehicles from the requirement. The court also found that the extension of the order to the entire fleet is appropriate, as the management of the company has not been cooperative in the past. [Extracted from the article]
