bayesian_cnn's Introduction

Bayesian CNN

We introduce Bayesian convolutional neural networks with variational inference, a variant of convolutional neural networks (CNNs), in which the intractable posterior probability distributions over weights are inferred by Bayes by Backprop. We demonstrate how our proposed variational inference method achieves performances equivalent to frequentist inference in identical architectures on several datasets (MNIST, CIFAR10, CIFAR100), while the two desiderata, a measure for uncertainty and regularization are incorporated naturally. We examine in detail how this measure for uncertainty, namely the predictive variance, can be decomposed into aleatoric and epistemic uncertainties.

One convolutional layer with distributions over weights in each filter

Distribution over weights in a CNN's filter.

Fully Bayesian perspective of an entire CNN

Distributions must be over weights in convolutional layers and weights in fully-connected layers.
