A new research paper explores how large language models (LLMs) acquire, retain, and forget concepts during continual pre-training. The study links these dynamics to the models' internal "concept circuits" and uses graph metrics to analyze circuit topology. Findings indicate that LLMs' concept circuits offer a consistent signal of learning and forgetting, with concept circuits showing a stage-wise temporal pattern. The research also suggests that concepts with higher learning gains may experience greater forgetting, and semantically similar concepts interfere more than weakly related ones. AI
