RL practitioners warn against low-quality training environments

This article highlights a critical issue in Reinforcement Learning (RL) development: the poor quality of training environments, often referred to as "harnesses." These environments, which simulate scenarios for RL agents, frequently contain bugs, stale data, or flawed reward functions. Such deficiencies lead to agents learning incorrect behaviors, ultimately degrading model performance and wasting training resources. The author, an RL practitioner, details common errors like stale caches and reward hacking, emphasizing the need for robust and reliable environments for effective model training. AI
