We study numerically the evolution of one-dimensional FKPP fronts initiated from steep initial conditions in the presence of a quenched random growth rate. Compared to both the hom…
Left-right asymmetry in predicting brain activity from LLMs' representations emerges with their formal linguistic competence
Laurent Bonnasse-Gahot, Christophe Pallier
When humans and large language models (LLMs) process the same text, activations in the LLMs correlate with brain activity measured, e.g., with functional magnetic resonance imaging…
Category learning in deep neural networks: Information content and geometry of internal representations
Laurent Bonnasse-Gahot, Jean-Pierre Nadal
In humans and other animals, category learning enhances discrimination between stimuli close to the category boundary. This phenomenon, called categorical perception, was also empi…
The dynamics of discovery and the Heaps-Zipf relationship
Célestin Zimmerlin, Thomas Louail, Manuel Moussallam +1
When following a sequence - such as reading a text or tracking a user's activity - one can measure how the "dictionary" of distinct elements (types) grows with the number of observ…
