Bayes Conditional Distribution Estimation for Knowledge Distillation Based on Conditional Mutual Information

1 code implementation16 Jan 2024 Linfeng Ye, Shayan Mohajer Hamidi, Renhao Tan, En-hui Yang

To improve this estimate for KD, in this paper we introduce the concept of conditional mutual information (CMI) into the estimation of BCPD and propose a novel estimator called the maximum CMI (MCMI) method.

Conditional Mutual Information Constrained Deep Learning for Classification

no code implementations17 Sep 2023 En-hui Yang, Shayan Mohajer Hamidi, Linfeng Ye, Renhao Tan, Beverly Yang

The concepts of conditional mutual information (CMI) and normalized conditional mutual information (NCMI) are introduced to measure the concentration and separation performance of a classification deep neural network (DNN) in the output probability distribution space of the DNN, where CMI and the ratio between CMI and NCMI represent the intra-class concentration and inter-class separation of the DNN, respectively.
