A new paper explores the phenomenon of "double descent" in machine learning, where neural networks continue to improve their generalization capabilities even as their complexity surpasses the amount of training data. Researchers utilized dynamical mean field theory to demonstrate that this behavior stems from a phase transition within the stochastic field theory governing the training process. This transition is characterized by a breakdown of the fluctuation-dissipation theorem due to broken ergodicity, with the network's generalization ability mirroring the London model of superconducting transitions.
