Self-Preservation in Language Models

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.

When to Review: Spaced Repetition for Continual Pre-Training of Language Models

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.

When to Review: Spaced Repetition for Continual Pre-Training of Language Models

The paper introduces Spaced Repetition Training (SRT), a continual learning framework that schedules sample rehearsal using the SM-2 algorithm. SRT tracks per-example review states and maps perplexity to recall quality, allowing the training loop to decide which examples to replay and when. Experiments on Wikipedia and code corpora show that SRT improves the stability‑plasticity trade‑off, recovers 5–37 percentage points of lost old‑knowledge accuracy, and preserves benchmark performance better than naive continual pre‑training or uniform replay.

Hidden Forgetting in Continual Multimodal Learning: When Accuracy Survives but Grounding Fails

arXiv:2607. 02020v1 Announce Type: new Abstract: Multimodal large language models must continually adapt to evolving tasks and domains, yet standard continual learning metrics mainly measure whether old answers remain correct, leaving the stability of multimodal grounding largely unexamined.
