New theory explains in-context learning vs. specialization in sequence models

By PulseAugur Editorial · [1 sources] ·

A new theoretical framework has been developed to explain the distinct ways sequence models generalize, focusing on extrapolation of training structures versus adaptation to novel tasks via prompts. This theory, applied to a solvable topic model, predicts the emergence of two solutions: a specialized predictor and an in-context predictor. The in-context predictor is available early in the training process, while the specialized predictor requires a significantly larger dataset relative to the model's parameters. AI

IMPACT Provides a theoretical understanding of how sequence models generalize, potentially guiding future model development and risk assessment.

    In-Context Learning Before Specialisation: Theory of Learning in a Solvable Topic Model

    arXiv:2610.21901v1 Announce Type: cross Abstract: Sequence models can generalise in fundamentally distinct ways: extrapolating structures seen in training, or using their prompt to adapt to novel tasks. The prevailing strategy determines how the model behaves beyond its training …
