Dimensionality and ramping: Signatures of sentence integration in the dynamics of brains and deep language models

2023-03-01

Abstract excerpt

A sentence is more than the sum of its words: its meaning depends on how they combine with one another. The brain mechanisms underlying such semantic composition remain poorly understood. To shed light on the neural vector code underlying semantic composition, we introduce two hypotheses: First, the intrinsic dimensionality of the space of neural representations should increase as a sentence unfolds, paralleling t...
