ECHO reportedly beats pure RL on score and efficiency in small robotics-like experiments

A user says the setup had a turn cap and no thinking to simulate time-constrained environments.

TLDR

A user describes small ECHO experiments in a robotics-like environment, using a turn cap and no thinking to simulate time constraints. They say ECHO performed better than pure reinforcement learning (RL) on score and efficiency, and that a short ECHO phase followed by RL worked well.

Billy Hoy@BillyHoy1_Can predicting environment observations help embodied agents? During my residency @PrimeIntellect, we tested ECHO on BabyAI in a constrained setting: limited turns and thinking disabled, focusing on immediate action-taking. We found improved held-out reward and rollout efficiency.3h
