Sparsifying Bayesian neural networks with latent binary variables and normalizing flows

1 code implementation5 May 2023 Lars Skaaret-Lund, Geir Storvik, Aliaksandr Hubin

In this paper, we will consider two extensions to the LBBNN method: Firstly, by using the local reparametrization trick (LRT) to sample the hidden units directly, we get a more computationally efficient algorithm.

Variational Inference for Bayesian Neural Networks under Model and Parameter Uncertainty

1 code implementation1 May 2023 Aliaksandr Hubin, Geir Storvik

Bayesian neural networks (BNNs) have recently regained a significant amount of attention in the deep learning community due to the development of scalable approximate Bayesian inference techniques.

A sequential Monte Carlo approach to estimate a time varying reproduction number in infectious disease models: the Covid-19 case

1 code implementation19 Jan 2022 Geir Storvik, Alfonso Diz-Louis Palomares, Solveig Engebretsen, Gunnar Øyvind Isaksson Rø, Kenth Engø-Monsen, Aja Bråthen Kristoffersen, Birgitte Freiesleben de Blasio, Arnoldo Frigessi

During the first months, the Covid-19 pandemic has required most countries to implement complex sequences of non-pharmaceutical interventions, with the aim of controlling the transmission of the virus in the population.

Reversible Genetically Modified Mode Jumping MCMC

no code implementations11 Oct 2021 Aliaksandr Hubin, Florian Frommlet, Geir Storvik

In this paper, we introduce a reversible version of a genetically modified mode jumping Markov chain Monte Carlo algorithm (GMJMCMC) for inference on posterior model probabilities in complex model spaces, where the number of explanatory variables is prohibitively large for classical Markov Chain Monte Carlo methods.

Deep Bayesian regression models

2 code implementations6 Jun 2018 Aliaksandr Hubin, Geir Storvik, Florian Frommlet

DBRM can easily be extended to include latent Gaussian variables to model complex correlation structures between observations, which seems to be not easily possible with existing deep learning approaches.

A novel algorithmic approach to Bayesian Logic Regression

1 code implementation22 May 2017 Aliaksandr Hubin, Geir Storvik, Florian Frommlet

Logic regression was developed more than a decade ago as a tool to construct predictors from Boolean combinations of binary covariates.
