On Local Posterior Structure in Deep Ensembles

AISTATS 2025poster

Bayesian Neural Networks (BNNs) often improve model calibration and predictive uncertainty quantification compared to point estimators such as maximum-a-posteriori (MAP). Similarly, deep ensembles (DEs) are also known to improve calibration, and therefore, it is natural to hypothesize that deep ense…

Towards Scalable Bayesian Transformers: Investigating stochastic subset selection for NLP

UAI 2024poster

Bayesian deep learning provides a framework for quantifying uncertainty. However, the scale of modern neural networks applied in Natural Language Processing (NLP) limits the usability of Bayesian methods. Subnetwork inference aims to approximate the posterior by selecting a stochastic parameter subs…

Learning To Generate 3d Representations of Building Roofs Using Single-View Aerial Imagery

ICASSP 2023accepted

We present a novel pipeline for learning the conditional distribution of a building roof mesh given pixels from an aerial image, under the assumption that roof geometry follows a set of regular patterns. Unlike alternative methods that require multiple images of the same object, our approach enables…

Challenges and Opportunities in High Dimensional Variational Inference

NeurIPS 2021poster

Current black-box variational inference (BBVI) methods require the user to make numerous design choices – such as the selection of variational objective and approximating family – yet there is little principled guidance on how to do so. We develop a conceptual framework and set of experimental tools…

Uncertainty-aware sensitivity analysis using Rényi divergences

UAI 2021poster

For nonlinear supervised learning models, assessing the importance of predictor variables or their interactions is not straightforward because importance can vary in the domain of the variables. Importance can be assessed locally with sensitivity analysis using general methods that rely on the model…

Unifying Probabilistic Models for Time-frequency Analysis

ICASSP 2019accepted

In audio signal processing, probabilistic time-frequency models have many benefits over their non-probabilistic counterparts. They adapt to the incoming signal, quantify uncertainty, and measure correlation between the signal’s amplitude and phase information, making time domain resynthesis straight…

Variable selection for Gaussian processes via sensitivity analysis of the posterior predictive distribution

AISTATS 2019poster

Variable selection for Gaussian process models is often done using automatic relevance determination, which uses the inverse length-scale parameter of each input variable as a proxy for variable relevance. This implicitly determined relevance has several drawbacks that prevent the selection of optim…

EEG source imaging assists decoding in a face recognition task

ICASSP 2017accepted

EEG based brain state decoding has numerous applications. State of the art decoding is based on processing of the multivariate sensor space signal, however evidence is mounting that EEG source reconstruction can assist decoding. EEG source imaging leads to high-dimensional representations and rather…
