Researchers introduce a controlled experimental framework using procedurally generated languages to study cross-lingual transfer in language models, isolating variables like lexical distance and tokenization.

Researchers propose a representation-readout decomposition framework that explains anomalous neural network training phenomena like grokking and double descent by analyzing two competing learning processes: representation learning in encoders and readout calibration in classifiers. The framework provides task-agnostic diagnostics that reveal these phenomena stem from fluctuations in relative learning speeds rather than mysterious delays, challenging existing lazy-to-rich learning theories.
