New research frames neural network optimizer bias as information allocation dynamics

By PulseAugur Editorial · [2 sources] ·

This paper introduces a new perspective on understanding optimizer implicit bias in neural network training. It proposes an "information allocation dynamics" approach, viewing bias as the relative distribution of training signals between weight-like and bias-like parameter pathways. This allocation can be controlled by a continuous "preconditioning exponent p", influencing how residual signals are preserved and updated. The research shifts the analysis of optimizer bias from the geometry of the final solution to the dynamic update processes during training, highlighting its impact on parameter trajectories and generalization.

    Different optimizers have different update biases, but these biases are usually implicit. Existing studies mainly analyze or control such biases from the geometry of the final solution. However, how optimizer bias forms during training still lacks a clear internal mechanism. This…
