Title: Information Theory meets Deep Learning
Abstract: In the era of data deluge, various deep learning algorithms have been proven extraordinarily successful in providing tools and paradigms for extracting information from massive data sets. Despite this success, relatively less attention has been paid to these algorithms’ fundamental limits and trade-offs. Information theory demonstrates excellent potential in this context. To bridge the gap between traditional information theory and real-world deep learning problems, we propose the matrix-based Renyi’s entropy functional from a sample-level, which evaluates information-theoretic quantities on the eigen-spectrum of symmetric positive definite (SPD) matrices without any density estimation and distributional assumptions. Based on the new entropy function, we demonstrate how information theory can be used to improve the generalization performances of deep neural networks. In this talk, we focus our discussions on two learning principles: 1) the minimum error entropy; and 2) the deep “deterministic” information bottleneck.
