Deep learning and the information bottleneck principle

TLDR
It is argued that both the optimal architecture, number of layers and features/connections at each layer, are related to the bifurcation points of the information bottleneck tradeoff, namely, relevant compression of the input layer with respect to the output layer.
Abstract
Deep Neural Networks (DNNs) are analyzed via the theoretical framework of the information bottleneck (IB) principle. We first show that any DNN can be quantified by the mutual information between the layers and the input and output variables. Using this representation we can calculate the optimal information theoretic limits of the DNN and obtain finite sample generalization bounds. The advantage of getting closer to the theoretical limit is quantifiable both by the generalization bound and by the network's simplicity. We argue that both the optimal architecture, number of layers and features/connections at each layer, are related to the bifurcation points of the information bottleneck tradeoff, namely, relevant compression of the input layer with respect to the output layer. The hierarchical representations at the layered network naturally correspond to the structural phase transitions along the information curve. We believe that this new insight can lead to new optimality bounds and deep learning algorithms.

Learning from the Best: Rationalizing Prediction by Adversarial Information Calibration

TL;DR: This work trains two models jointly: one is a typical neural model that solves the task at hand in an accurate but black-box manner, and the other is a selector-predictor model that additionally produces a rationale for its prediction.

An Information Theoretic Interpretation to Deep Neural Networks

TL;DR: This paper shows that the features extracted by DNN coincide with the result of an optimization problem, which it is called the "universal feature selection" problem, in a local analysis regime, which has direct operational meaning in terms of the performance for inference tasks.

InfoBERT: Improving Robustness of Language Models from An Information Theoretic Perspective

TL;DR: InfoBERT as discussed by the authors proposes two mutual-information-based regularizers for model training: (i) an Information Bottleneck regularizer, which suppresses noisy mutual information between the input and the feature representation; and (ii) a Robust Feature regularizer.
