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.
Timeline (last 90 days)
Experience replay in continual learning is usually implemented in two ways: rehearsal (maintaining a buffer of old-task samples and mixing old samples in when training new tasks) and pseudo-rehearsal (using generative models to synthesize old data).
Deep reinforcement learning requires stabilization techniques such as experience replay and target networks to cope with the instability and divergence risks brought by function approximation.
Methods such as experience replay, opponent modeling or policy regularization often assume that non-stationarity is bounded or predictable.
Lossless memory solutions make a trade-off between storage cost and information fidelity that favors fidelity.

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.
