The Self-Improving Loops for Visual Robotic Planning (SILVR) framework enables in-domain visual robotic planners to continuously enhance their performance on novel tasks by iteratively learning from self-collected online experience. This approach yields up to 285% improvement in success rates on simulated MetaWorld tasks and substantial gains in real-world manipulation, outperforming baseline methods and demonstrating robustness to varying data quality.

Key insights

  • Iterative finetuning of a visual planner with self-collected online experience, particularly when composed with internet-scale video priors, leads to continuous performance gains on novel robotic tasks.
  • Visual planning-based self-improvement demonstrates superior sample efficiency compared to direct reinforcement learning finetuning of action-predicting policies for online adaptation.
  • The framework exhibits robustness to suboptimal initial training data and varying feedback mechanisms, including VLM-based filtering or no explicit success filtering, in enabling sustained improvement.
