Predicting COVID-19 positivity and hospitalization with multi-scale graph neural networks

The pandemic of COVID-19 is undoubtedly one of the biggest challenges for modern healthcare. In order to analyze the spatio-temporal aspects of the spread of COVID-19, technology has helped us to track, identify and store information regarding …

Prediction of cesarean delivery in class III obese nulliparous women: An externally validated model using machine learning

Background: class III obese women, are at a higher risk of cesarean section during labor, and cesarean section is responsible for increased maternal and neonatal morbidity in this population. Objective: the objective of this project was to develop a …

Solid Harmonic Wavelet Bispectrum for Image Analysis

The Solid Harmonic Wavelet Bispectrum in 2D provides a multi-scale, rotation- and translation-covariant representation that preserves relative phase and captures higher-order interactions between wavelet responses. This representation encodes rich …

Efficient spatio-temporal feature clustering for large event-based datasets

Event-based cameras encode changes in a visual scene with high temporal precision and low power consumption, generating millions of events per second in the process. Current event-based processing algorithms do not scale well in terms of runtime and …

Dissecting Self-Supervised Learning Methods for Surgical Computer Vision

The field of surgical computer vision has undergone considerable breakthroughs in recent years with the rising popularity of deep neural network-based methods. However, standard fully-supervised approaches for training such models require vast …

Solid harmonic wavelet scattering for predictions of molecule properties

We present a machine learning algorithm for the prediction of molecule properties inspired by ideas from density functional theory (DFT). Using Gaussian-type orbital functions, we create surrogate electronic densities of the molecule from which we …

Discrete Sparse Coding

Sparse coding algorithms with continuous latent variables have been the subject of a large number of studies. However, discrete latent spaces for sparse coding have been largely ignored. In this work, we study sparse coding with latents described by …
