When Does Predictive Inverse Dynamics Outperform Behavior Cloning?
Researchers provide theoretical and empirical evidence that Predictive Inverse Dynamics Models (PIDM) outperform traditional Behavior Cloning in offline imitation learning by introducing a bias-variance tradeoff. PIDM requires significantly fewer expert demonstrations—up to 5x fewer in 2D tasks and 66% fewer in complex 3D environments—while maintaining comparable performance, offering practical advantages for training AI systems with limited data.
