abstract

If the behavior of a system with many degrees of freedom can be captured by a small number of collective variables, then plausibly there is an underlying mean-field theory. We show that simple versions of this idea fail to describe the patterns of activity in networks of real neurons. An extended mean-field theory that matches the distribution of collective variables is at least consistent, though shows signs that these networks are poised near a critical point, in agreement with other observations. These results suggest a path to analysis of emerging data on ever larger numbers of neurons.

Minimax entropy: The statistical physics of optimal models

q-bio.QM · 2025-05-02 · conditional · novelty 4.0

Starting from minimum description length, the paper derives and reviews the minimax entropy principle: the optimal features are those that yield the maximum entropy model with the lowest entropy.
