Researchers have developed a new framework for optimizing data selection in large language models, adapting data weighting to specific tasks and models using efficient proxies. Another study investigates categorical perception in LLM hidden states, finding geometric warping at digit-count boundaries across various model families. This warping effect, termed "structural CP," appears to be an architectural property independent of explicit semantic knowledge. AI
