Isotropic SGD: a Practical Approach to Bayesian Posterior Sampling

no code implementations9 Jun 2020 Giulio Franzese, Rosa Candela, Dimitrios Milios, Maurizio Filippone, Pietro Michiardi

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 sampling (SGMCMC) algorithms.

Model Monitoring and Dynamic Model Selection in Travel Time-series Forecasting
