Improving Deep Dynamics Models for Autonomous Vehicles with Multimodal Latent Mapping of Surfaces

no code implementations21 Mar 2023 Johan Vertens, Nicolai Dorka, Tim Welschehold, Michael Thompson, Wolfram Burgard

By training everything end-to-end with the loss of the dynamics model, we enforce the latent mapper to learn an update rule for the latent map that is useful for the subsequent dynamics model.

Scheduled Intrinsic Drive: A Hierarchical Take on Intrinsically Motivated Exploration

no code implementations18 Mar 2019 Jingwei Zhang, Niklas Wetzel, Nicolai Dorka, Joschka Boedecker, Wolfram Burgard

Many state-of-the-art methods use intrinsic motivation to complement the sparse extrinsic reward signal, giving the agent more opportunities to receive feedback during exploration.
