Hybrid language model for robotics shows mixed results with geometric conditioning

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the impact of physical-state inputs on a 0.8 billion parameter hybrid language model designed for manipulation tasks. The study trained six different conditioning methods on three LIBERO-Spatial tasks, evaluating their performance across multiple seeds and rollouts. Results indicated that conditioning decay gates on geometric increments achieved 28.9% success, while shuffling these increments led to 36.7% success, and explicit object/goal geometry resulted in 24.4% success. Robustness tests revealed that a state-only relative-coordinate policy maintained 7 out of 10 successes under frame relabeling, whereas visual policies struggled significantly with object displacement.
