Hybrid unadjusted Langevin methods for high-dimensional latent variable models

no code implementations26 Jun 2023 Ruben Loaiza-Maya, Didier Nibbering, Dan Zhu

The method employs the Fisher identity to integrate out the latent variables, which makes it accurate and computationally feasible when applied to big data.

Bayesian Neural Network Versus Ex-Post Calibration For Prediction Uncertainty

1 code implementation29 Sep 2022 Satya Borgohain, Klaus Ackermann, Ruben Loaiza-Maya

Probabilistic predictions from neural networks which account for predictive uncertainty during classification is crucial in many real-world and high-impact decision making settings.

Scalable Bayesian estimation in the multinomial probit model

no code implementations26 Jul 2020 Ruben Loaiza-Maya, Didier Nibbering

Because current model specifications employ a full covariance matrix of the latent utilities for the choice alternatives, they are not scalable to a large number of choice alternatives.

Variational Bayes Estimation of Discrete-Margined Copula Models with Application to Time Series

no code implementations26 Dec 2017 Ruben Loaiza-Maya, Michael Stanley Smith

We propose a new variational Bayes estimator for high-dimensional copulas with discrete, or a combination of discrete and continuous, margins.
