Accelerating Model-Based Reinforcement Learning with State-Space World Models

no code implementations27 Feb 2025 Maria Krinner, Elie Aljalbout, Angel Romero, Davide Scaramuzza

However, training a world model alongside the policy increases the computational complexity, leading to longer training times that are often intractable for complex real-world scenarios.

Multi-Task Reinforcement Learning for Quadrotors

no code implementations17 Dec 2024 Jiaxu Xing, Ismail Geles, Yunlong Song, Elie Aljalbout, Davide Scaramuzza

Reinforcement learning (RL) has shown great effectiveness in quadrotor control, enabling specialized policies to develop even human-champion-level performance in single-task scenarios.

Student-Informed Teacher Training

no code implementations12 Dec 2024 Nico Messikommer, Jiaxu Xing, Elie Aljalbout, Davide Scaramuzza

In this framework, a teacher is trained with privileged task information, while a student tries to predict the actions of the teacher with more limited observations, e. g., in a robot navigation task, the teacher might have access to distances to nearby obstacles, while the student only receives visual observations of the scene.

LIMT: Language-Informed Multi-Task Visual World Models

no code implementations18 Jul 2024 Elie Aljalbout, Nikolaos Sotirakis, Patrick van der Smagt, Maximilian Karl, Nutan Chen

Our results highlight the benefits of using language-driven task representations for world models and a clear advantage of model-based multi-task learning over the more common model-free paradigm.

The Shortcomings of Force-from-Motion in Robot Learning

no code implementations3 Jul 2024 Elie Aljalbout, Felix Frank, Patrick van der Smagt, Alexandros Paraschos

Robotic manipulation requires accurate motion and physical interaction control.

Guided Decoding for Robot On-line Motion Generation and Adaption

no code implementations22 Mar 2024 Nutan Chen, Botond Cseke, Elie Aljalbout, Alexandros Paraschos, Marvin Alles, Patrick van der Smagt

We present a novel motion generation approach for robot arms, with high degrees of freedom, in complex settings that can adapt online to obstacles or new via points.

Dual-Arm Adversarial Robot Learning

no code implementations15 Oct 2021 Elie Aljalbout

This is due to the additional challenges encountered in the real-world, such as noisy sensors and actuators, safe exploration, non-stationary dynamics, autonomous environment resetting as well as the cost of running experiments for long periods of time.

Learning to Centralize Dual-Arm Assembly

no code implementations8 Oct 2021 Marvin Alles, Elie Aljalbout

Hence, to avoid modeling the interaction between the two robots and the used assembly tools, we present a modular approach with two decentralized single-arm controllers which are coupled using a single centralized learned policy.
