The paper investigates how language models can aid their own continual learning by generating replay data and selecting preservation targets. By organizing task descriptions into Task Banks, the authors show that replay generated by frozen models reduces forgetting on tasks outside the bank and that informed selection of replay targets can improve retention. The study demonstrates that models can support broader self‑preservation, especially when larger models are used, and that replacing new‑task examples with replay can enhance preservation under a fixed example budget.

The paper introduces Golden-GRPO Injection (GRIN), a three-stage self‑learning framework that uses a mixed‑policy reinforcement learning algorithm to inject knowledge into large language models. GRIN injects a golden answer to provide learning signals even when on‑policy rollouts fail on novel facts, and is evaluated on two new document‑level benchmarks—Blank and Counter—that test novel acquisition and counterfactual overwrite. Experiments show that mixed‑policy RL enables knowledge absorption beyond what supervised fine‑tuning can achieve, with GRIN outperforming SFT and other RL baselines on harder question types while matching them on basic fact recall.

The paper introduces Spaced Repetition Training (SRT), a continual learning framework that adapts review scheduling for language models by using the SM-2 algorithm to decide which past examples to replay. SRT tracks per-example review states and maps perplexity to a recall-quality signal, allowing the model to retain old knowledge while consolidating new information without changing the underlying model or training objective. Experiments on Wikipedia and code corpora show that SRT improves the stability-plasticity trade‑off, recovers 5–37 percentage points of lost accuracy, and maintains benchmark performance better than naive continual pre‑training or uniform replay; similar benefits are observed in vision and tabular data when an appropriate recall signal is used.
