Researchers have proposed a new framework for understanding how Large Language Models (LLMs) learn within a given context. Their work suggests that LLMs update their behavior by performing Bayesian inference over a low-dimensional geometric space, termed a conceptual belief space. By analyzing LLMs' performance on story understanding tasks, the study found that these belief updates follow predictable trajectories on structured manifolds, which are reflected in both the models' external behavior and internal representations. Furthermore, interventions on these internal representations could causally influence the belief trajectories, supporting the geometric account of LLM belief dynamics. AI
