vEDGAR -- Can CARLA Do HiL?
Gehrke, Nils, Brecht, David, Kulmer, Dominik, Patel, Dheer, Diermeyer, Frank
Simulation offers advantages throughout the development process of automated driving functions, both in research and product development. Common open-source simulators like CARLA are extensively used in training, evaluation, and software-in-the-loop testing of new automated driving algorithms. However, the CARLA simulator lacks an evaluation where research and automated driving vehicles are simulated with their entire sensor and actuation stack in real time. The goal of this work is therefore to create a simulation framework for testing the automation software on its dedicated hardware and identifying its limits. Achieving this goal would greatly benefit the open-source development workflow of automated driving functions, designating CARLA as a consistent evaluation tool along the entire development process. To achieve this goal, in a first step, requirements are derived, and a simulation architecture is specified and implemented. Based on the formulated requirements, the proposed vEDGAR software is evaluated, resulting in a final conclusion on the applicability of CARLA for HiL testing of automated vehicles. The tool is available open source: Modified CARLA fork: https://github.com/TUMFTM/carla, vEDGAR Framework: https://github.com/TUMFTM/vEDGAR

Towards the Detection of Building Occupancy with Synthetic Environmental Data
Weber, Manuel, Doblander, Christoph, Mandl, Peter
Information about room-level occupancy is crucial to many building-related tasks, such as building automation or energy performance simulation. Current occupancy detection literature focuses on data-driven methods, but is mostly based on small case studies with few rooms. The necessity to collect room-specific data for each room of interest impedes applicability of machine learning, especially data-intensive deep learning approaches, in practice. To derive accurate predictions from less data, we suggest knowledge transfer from synthetic data. In this paper, we conduct an experiment with data from a CO$_2$ sensor in an office room, and additional synthetic data obtained from a simulation. Our contribution includes (a) a simulation method for CO$_2$ dynamics under randomized occupant behavior, (b) a proof of concept for knowledge transfer from simulated CO$_2$ data, and (c) an outline of future research implications. From our results, we can conclude that the transfer approach can effectively reduce the required amount of data for model training.

The target, or label, is the value that encodes the information we want to learn. Instead, we express the loss in an equivalent but more verbose way. In the previous Section, we defined the contrastive loss for the entire dataset (14). This intuition is formalized by the following Definition and Proposition. Then the loss, as defined in Eq. 14, can be approximated by using the target in Eq. 20 with L (; D) |D The equality is proven by applying the logic of Eq. 19 two times independently, once for the We highlight that this scaling is linear, and thus is reflected in both first and second-order derivatives.

Remarkable robot images provide a vision of the future
Rollin' Justin can avoid obstacles and serve drinks, among other tasks We have long been fascinated with our own image. In the 1920s play, Czech writer Karel Čapek coined the term robot to describe human-looking creatures forced to work in factories. Since then, we have built many humanoid robots that can move and interact with the world in anthropomorphic ways. Award-winning photographer Henrik Spohler at photo agency laif explores such endeavours in his project Tomorrow Is the Question . The main image, above, shows a metallic creation by the German Aerospace Center's Institute of Robotics and Mechatronics in Oberpfaffenhofen.

Incorporating Quality of Life in Climate Adaptation Planning via Reinforcement Learning
Costa, Miguel, Vandervoort, Arthur, Drews, Martin, Morrissey, Karyn, Pereira, Francisco C.
Urban flooding is expected to increase in frequency and severity as a consequence of climate change, causing wide-ranging impacts that include a decrease in urban Quality of Life (QoL). Meanwhile, policymakers must devise adaptation strategies that can cope with the uncertain nature of climate change and the complex and dynamic nature of urban flooding. Reinforcement Learning (RL) holds significant promise in tackling such complex, dynamic, and uncertain problems. Because of this, we use RL to identify which climate adaptation pathways lead to a higher QoL in the long term. We do this using an Integrated Assessment Model (IAM) which combines a rainfall projection model, a flood model, a transport accessibility model, and a quality of life index. Our preliminary results suggest that this approach can be used to learn optimal adaptation measures and it outperforms other realistic and real-world planning strategies.

BUILDA: A Thermal Building Data Generation Framework for Transfer Learning
Krug, Thomas, Raisch, Fabian, Aimer, Dominik, Wirnsberger, Markus, Sigg, Ferdinand, Schäfer, Benjamin, Tischler, Benjamin
Transfer learning (TL) can improve data-driven modeling of building thermal dynamics. Therefore, many new TL research areas emerge in the field, such as selecting the right source model for TL. However, these research directions require massive amounts of thermal building data which is lacking presently. Neither public datasets nor existing data generators meet the needs of TL research in terms of data quality and quantity. Moreover, existing data generation approaches typically require expert knowledge in building simulation. We present BuilDa, a thermal building data generation framework for producing synthetic data of adequate quality and quantity for TL research. The framework does not require profound building simulation knowledge to generate large volumes of data. BuilDa uses a single-zone Modelica model that is exported as a Functional Mock-up Unit (FMU) and simulated in Python. We demonstrate BuilDa by generating data and utilizing it for pretraining and fine-tuning TL models.
