Notes on Margin Training and Margin p-Values for Deep Neural Network Classifiers

This work addresses theoretical and practical aspects of margin-based analysis for DNN classifiers, which is incremental as it builds on existing margin concepts without introducing a new paradigm.

The authors tackled the problem of understanding and improving classification margins in deep neural networks by proving a new local class-purity theorem for Lipschitz continuous classifiers and developing methods to achieve training margins and compute margin p-values for test samples.
