Speed Limits for Deep Learning

Inbar Seroussi, Alexander A. Alemi, Moritz Helias +1

State-of-the-art neural networks require extreme computational power to train. It is therefore natural to wonder whether they are optimally trained. Here we apply a recent advancem…

Variational Prediction

Alexander A. Alemi, Ben Poole

Bayesian inference offers benefits over maximum likelihood, but it also comes with computational costs. Computing the posterior is typically intractable, as is marginalizing that p…

Does Knowledge Distillation Really Work?

Samuel Stanton, Pavel Izmailov, Polina Kirichenko +2

Knowledge distillation is a popular technique for training a small student network to emulate a larger teacher model, such as an ensemble of networks. We show that while knowledge…

VIB is Half Bayes

Alexander A Alemi, Warren R Morningstar, Ben Poole +2

In discriminative settings such as regression and classification there are two random variables at play, the inputs X and the targets Y. Here, we demonstrate that the Variational I…

PAC-Bayes: Narrowing the Empirical Risk Gap in the Misspecified Bayesian Regime

Warren R. Morningstar, Alexander A. Alemi, Joshua V. Dillon

The Bayesian posterior minimizes the "inferential risk" which itself bounds the "predictive risk". This bound is tight when the likelihood and prior are well-specified. However sin…

Density of States Estimation for Out-of-Distribution Detection

Warren R. Morningstar, Cusuh Ham, Andrew G. Gallagher +3

Perhaps surprisingly, recent studies have shown probabilistic model likelihoods have poor specificity for out-of-distribution (OOD) detection and often assign higher likelihoods to…
