cross-episode-memory

Introduces Self-Review Reinforcement Learning (SRRL), a training framework that embeds a self-review step into RL episodes to transform sparse environmental feedback into behavioral improvements, using cross-episode memory and selective policy distillation. Evaluated on GSM8K, SRRL outperforms standard RLVR with GRPO across Qwen 3-4B and OLMo-3-7B models.
