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.
