Overview

Addresses reward design challenges in robotic manipulation via principled progress modeling.

Core Technique

General Reward Model:

# Hop-based progress: normalized by task span
progress = model.predict_progress(observation, task_span)

# Multi-view fusion
fused_progress = aggregate_views([view1, view2, view3])

# Policy-Invariant Reward Shaping
reward = outcome_reward + policy_invariant_shaping(fused_progress)

Performance

  • 92.8% task completion accuracy
  • 95% success within 150 interactions
  • Theoretically grounded reward shaping
