New research frames neural network training as matrix dynamics and phase transitions

By PulseAugur Editorial · [2 sources] ·

Two new arXiv papers explore the internal dynamics of neural networks during training, moving beyond scalar loss functions to analyze the evolution of internal representations. The first paper introduces Observable Matrix Dynamics (OMD) to study spectral reorganizations in distance matrices of input representations, distinguishing between diffusive and phase transition regimes. The second paper frames neural network training as a stochastic evolution of matrix ensembles, identifying a Baik-Ben Arous-Péché (BBP) transition that signals representation formation and links trainability to optimization hyperparameters. AI

    Learning as Observable Matrix Dynamics: Diffusive Relaxations versus Phase Transitions

    arXiv:2606.29679v1 Announce Type: new Abstract: Observable Matrix Dynamics (OMD) is a diagnostic framework that probes the dynamics of high-dimensional internal representations of inputs by a neural network via a fixed-size $N \times N$ distance matrix $M(t)$ on a held set of $N$…

    Spectral phase transitions and trainability in neural network learning dynamics

    arXiv:2606.28486v1 Announce Type: cross Abstract: The emergence of low-dimensional structures in the spectra of neural network weight matrices is a common empirical feature of trained models, but the dynamical origin of this phenomenon during learning remains an open problem. We …
