New research details sample efficiency of Inverse Dynamics Models in imitation learning

A new research paper explores the sample efficiency of Inverse Dynamics Models (IDMs) in semi-supervised imitation learning. The study demonstrates that VM-IDM and IDM labeling methods learn the same policy in a limiting case, termed the IDM-based policy. Researchers attribute the superior sample efficiency of IDM-based policies to their lower complexity hypothesis class and reduced stochasticity compared to expert policies, supported by statistical learning theory and experiments on benchmarks like Procgen and LIBERO. The paper also introduces an improved LAPO algorithm for latent action policy learning. AI

IMPACT Provides theoretical insights into sample efficiency for imitation learning, potentially improving agent performance in complex environments.

    On the Sample Efficiency of Inverse Dynamics Models for Semi-Supervised Imitation Learning

    arXiv:2602.02762v2 Announce Type: replace Abstract: Semi-supervised imitation learning (SSIL) consists in learning a policy from a small dataset of action-labeled trajectories and a much larger dataset of action-free trajectories. Some SSIL methods learn an inverse dynamics model…
