A Tub file is a specific type of file used in the context of machine learning, particularly with the DQN (Deep Q-Network) agents in the OpenAI Gym or similar environments. The term "Tub" can refer to a collection of experience data that an agent gathers during its training process. This data typically includes observations, actions, rewards, and next observations—components that are crucial for training reinforcement learning algorithms.
