Experience Replay is a pivotal technique in the realm of reinforcement learning (RL), a subset of artificial intelligence (AI) focused on training models to make sequences of decisions. By storing the agent's experiences at each step of the environment interaction in a memory buffer and then randomly sampling from this buffer to perform learning updates, Experience Replay breaks the temporal correlations in the observation sequence. This method not only enhances the efficiency and stability of the learning process but also allows the reuse of past experiences, making it a cornerstone for training deep reinforcement learning (DRL) models.
Applications in AI
Experience Replay is primarily utilized in reinforcement learning, particularly in scenarios where efficient learning from limited interactions is crucial:
