Understanding Gradient Regularization in Deep Learning: Efficient Finite-Difference Computation and Implicit Bias

ICML 2023poster

Gradient regularization (GR) is a method that penalizes the gradient norm of the training loss during training. While some studies have reported that GR can improve generalization performance, little attention has been paid to it from the algorithmic perspective, that is, the algorithms of GR that e…

Layer-Wise Interpretation of Deep Neural Networks using Identity Initialization

ICASSP 2021accepted

The interpretability of neural networks (NNs) is a challenging but essential topic for transparency in the decision-making process using machine learning. One of the reasons for the lack of interpretability is random weight initialization, where the input is randomly embedded into a different featur…

The Spectrum of Fisher Information of Deep Networks Achieving Dynamical Isometry

AISTATS 2021poster

The Fisher information matrix (FIM) is fundamental to understanding the trainability of deep neural nets (DNN), since it describes the parameter space’s local metric. We investigate the spectral distribution of the conditional FIM, which is the FIM given a single sample, by focusing on fully-connect…
