Introduces 9 synthetic annotation tasks and benchmarks for behavioral cloning, finding hierarchical skill learning, scaling benefits, effective multi-task pretraining, and shared internal representations of task phases and mistakes.
A new pipeline identifies candidate simplex geometries in Gemma-2-9B representations, with five clusters showing significant barycentric prediction advantages consistent with belief-state encoding.
LLMs fail at extended counting of repeated characters due to finite internal states, with abrupt errors persisting across model scales and inference methods.
Large language models preserve a geometric substrate in value representations that correlates with uncertainty and matches patterns from small models performing exact Bayesian inference.
Gradient Smoothing applies depth-wise smoothing to optimizer updates from base methods like Adam, yielding consistent gains in optimization and generalization on language, RL, diffusion, and vision tasks.
