Model Selection for Bayesian Autoencoders

Ba-Hien Tran, Simone Rossi, Dimitrios Milios +3

We develop a novel method for carrying out model selection for Bayesian autoencoders (BAEs) by means of prior hyper-parameter optimization. Inspired by the common practice of type-…

Revisiting the Effects of Stochasticity for Hamiltonian Samplers

Giulio Franzese, Dimitrios Milios, Maurizio Filippone +1

We revisit the theoretical properties of Hamiltonian stochastic differential equations (SDES) for Bayesian posterior sampling, and we study the two types of errors that arise from…

Sparse within Sparse Gaussian Processes using Neighbor Information

Gia-Lac Tran, Dimitrios Milios, Pietro Michiardi +1

Approximations to Gaussian processes based on inducing variables, combined with variational inference techniques, enable state-of-the-art sparse approaches to infer GPs at scale th…

Isotropic SGD: a Practical Approach to Bayesian Posterior Sampling

Giulio Franzese, Rosa Candela, Dimitrios Milios +2

In this work we define a unified mathematical framework to deepen our understanding of the role of stochastic gradient (SG) noise on the behavior of Markov chain Monte Carlo sampli…

A Variational View on Bootstrap Ensembles as Bayesian Inference

Dimitrios Milios, Pietro Michiardi, Maurizio Filippone

In this paper, we employ variational arguments to establish a connection between ensemble methods for Neural Networks and Bayesian inference. We consider an ensemble-based scheme w…

A Data-Driven Approach to Dynamically Adjust Resource Allocation for Compute Clusters

Francesco Pace, Dimitrios Milios, Damiano Carra +2

Nowadays, data-centers are largely under-utilized because resource allocation is based on reservation mechanisms which ignore actual resource utilization. Indeed, it is common to r…
