Neural Quadratic Forms unify learning dynamics across architectures

Researchers have introduced Neural Quadratic Forms (NQF) as a unified minimal model to explain the learning dynamics of neural networks. This model unifies various architectures like perceptrons, attention layers, and mixtures of experts by abstracting their specific details into a single "structure matrix." The theory predicts that training losses follow smooth power laws or exhibit sudden learning, depending on the initial weight magnitudes and data characteristics. These predictions have been numerically confirmed across different training methods and architectures. AI

IMPACT Provides a unified theoretical framework for understanding diverse neural network learning behaviors, potentially guiding future architectural designs.

    Neural Quadratic Forms: A Unified Minimal Model for Sudden Learning and Scaling Laws

    arXiv:2608.13335v1 Announce Type: new Abstract: Neural networks trained by gradient descent on a smooth cost function can nevertheless learn in steps: the cost holds on long plateaus and then drops abruptly. Meanwhile, training losses instead follow smooth power laws. Variants of…
