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.

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.

skweak: Weak Supervision Made Easy for NLP

1 code implementation ACL 2021 Pierre Lison, Jeremy Barnes, Aliaksandr Hubin

skweak is especially designed to facilitate the use of weak supervision for NLP tasks such as text classification and sequence labelling.

Flexible Bayesian Nonlinear Model Configuration

1 code implementation5 Mar 2020 Aliaksandr Hubin, Geir Storvik, Florian Frommlet

In this paper, we introduce a flexible approach for the construction and selection of highly flexible nonlinear parametric regression models.

An adaptive simulated annealing EM algorithm for inference on non-homogeneous hidden Markov models

1 code implementation20 Dec 2019 Aliaksandr Hubin

Non-homogeneous hidden Markov models (NHHMM) are a subclass of dependent mixture models used for semi-supervised learning, where both transition probabilities between the latent states and mean parameter of the probability distribution of the responses (for a given state) depend on the set of $p$ covariates.

Combining Model and Parameter Uncertainty in Bayesian Neural Networks

1 code implementation18 Mar 2019 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.

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.
