Experience Replay
A core technique in deep reinforcement learning introduced by DeepMind in the 2013 DQN paper. It stores agent-environment interaction tuples of state, action, reward, and next state in a replay buffer, then randomly samples from it during training to break temporal correlations and improve sample efficiency.
Core Facts
The three main strategies for mitigating catastrophic forgetting are regularization-based methods (such as EWC), replay-based methods (such as Experience Replay), and architecture-based methods (such as Progressive Neural Networks).
DeepMind published a paper in 2013 demonstrating a system capable of teaching itself to play Atari games.

经验回放将交互经验存入固定大小缓冲区并随机采样小批量训练，打破连续经验的时间相关性，使神经网络训练更稳定
经验回放最早在DeepMind的DQN算法中被提出，智能体将过去的交互经验存储在缓冲区中，训练时随机采样以提高样本利用效率
Solutions to mitigate catastrophic forgetting include Elastic Weight Consolidation (EWC), progressive network expansion, and experience replay, but no method has yet perfectly solved all problems.
