Where Should Action Generation Begin? A Learnable Source Prior for Generative Robot Policies
arXiv:2606.17408v1 Announce Type: cross Abstract: Generative robot policies typically begin action generation from an observation-independent standard Gaussian distribution, leaving the choice of source distribution underexplored. This work asks a simple question: where should action generation begin? We propose LeaP, a Learnable source Prior that replaces the standard Gaussian with a proprioception-conditioned diagonal Gaussian over action chunks. Parameterized by a lightweight MLP, LeaP jointly predicts the mean and state-adaptive variance of the source distribution, while keeping the downst
This work represents an incremental but significant improvement in the foundational methods for generative robot policies, building on recent advances in AI for robotic control and action generation.
Improving the efficiency and coherence of generative robot policies brings closer the practical deployment of more capable autonomous robotic systems, impacting various industries.
Robot policies can now leverage a learnable, state-adaptive source prior for action generation, potentially leading to more robust and context-aware robotic behaviors.
