An Empirical Study on What Matters for Viewpoint-Generalizable Policies in Visual Imitation Learning

A controlled empirical study of which design choices allow visuomotor policies to generalize across viewpoints finds that viewpoint generalization improves when dense visual tokens are retained and the action head participates in geometric reasoning.

SeeQ: Training Generalist Value Functions for Long-Horizon Robotic Manipulation

This work introduces SeeQ (Subtask-elicited Q-functions), which instead learns Q-values for the currently active subtask, which substantially improves best-of-N policy steering on real-world manipulation tasks.

$R^3$: Training Robots to Reason in Natural Language via Reinforcement Learning

This paper introduces a simple post-training recipe that turns off-the-shelf VLMs into robotic reasoners, and suggests that free-form language reasoning can function as a test-time compute mechanism for steering low-level policies.
