Research paper analyzes failures in Latent Action Models

This paper delves into the challenges of Latent Action Models (LAMs) in learning action representations from unlabeled videos. The research identifies that exogenous state, such as background clutter, interferes with reliable latent action learning by introducing changes unrelated to the agent's actions. The study analytically extends a linear LAM framework to model this exogenous state, revealing that standard reconstruction objectives can lead to latent actions encoding future exogenous information. The findings suggest that focusing on endogenous components within the representation space is crucial for mitigating this interference, and that auxiliary objectives like action-supervision can promote consistency across different exogenous states.
