New RECALL method improves VLA model learning with active data collection

Researchers have introduced RECALL, a novel approach to active lifelong learning for Vision-Language-Action (VLA) models. Unlike passive imitation learning, which requires failures to trigger data collection and offers little guidance on necessary supervision, RECALL uses uncertainty-guided data collection for more efficient fine-tuning. However, the study also highlights the challenge of catastrophic forgetting when fine-tuning solely on this new recovery data, exploring techniques like replay-based data mixing and elastic weight consolidation to balance plasticity and retention.

    RECALL: Recovery Experience Collection for Active Lifelong Learning in Vision-Language-Action Models

    Vision-Language-Action (VLA) models are commonly fine-tuned through passive imitation learning, where additional demonstrations are collected for tasks where the policy performs poorly. This approach incurs several downsides: it requires the robot to fail before data collection i…
