Reinforcement Learning with Action Sequence for Data-Efficient Robot Learning

Y Seo, P Abbeel - arxiv preprint arxiv:2411.12155, 2024 - arxiv.org
Training reinforcement learning (RL) agents on robotic tasks typically requires a large

Simplifying Latent Dynamics with Softly State-Invariant World Models

T Saanum, P Dayan, E Schulz - The Thirty-eighth Annual Conference on … - openreview.net
To solve control problems via model-based reasoning or planning, an agent needs to know
how its actions affect the state of the world. The actions an agent has at its disposal often …

Two-shot learning of continuous interpolation using a conceptor-aided recurrent autoencoder

Generalizing from only two time series towards unseen intermediate patterns poses a
significant challenge in representation learning. In this paper, we introduce a novel …
