Spatio-Temporal Attention in Multi-Granular Brain Chronnectomes for Detection of Autism Spectrum Disorder

Authors: James Orme-Rogers, Ajitesh Srivastava

arXiv

The traditional methods for detecting autism spectrum disorder (ASD) are expensive, subjective, and time-consuming, often taking years for a diagnosis, with many children growing well into adolescence...

New Interpretable Patterns and Discriminative Features from Brain Functional Network Connectivity Using Dictionary Learning

Authors: Fateme Ghayem, Hanlu Yang, Furkan Kantar, Seung-Jun Kim, Vince D. Calhoun, Tulay Adali

arXiv

Independent component analysis (ICA) of multi-subject functional magnetic resonance imaging (fMRI) data has proven useful in providing a fully multivariate summary that can be used for multiple purpos...

Age Prediction Performance Varies Across Deep, Superficial, and Cerebellar White Matter Connections

Authors: Yuxiang Wei, Tengfei Xue, Yogesh Rathi, Nikos Makris, Fan Zhang, Lauren J. O'Donnell

arXiv

The brain's white matter (WM) undergoes developmental and degenerative processes during the human lifespan. To investigate the relationship between WM anatomical regions and age, we study diffusion ma...

Rethinking Spatial Invariance of Convolutional Networks for Object Counting

Authors: Zhi-Qi Cheng, Qi Dai, Hong Li, JingKuan Song, Xiao Wu, Alexander G. Hauptmann

arXiv

Previous work generally believes that improving the spatial invariance of convolutional networks is the key to object counting. However, after verifying several mainstream counting networks, we surpri...

Effectiveness of a time to fixate for fitness to drive evaluation in neurological patients

Authors: Nadica Miljković, Jaka Sodnik

arXiv

We present a method to automatically calculate time to fixate (TTF) from the eye-tracker data in subjects with neurological impairment using a driving simulator. TTF presents the time interval for a p...

PAVI: Plate-Amortized Variational Inference

Authors: Louis Rouillard, Thomas Moreau, Demian Wassermann

arXiv

Given some observed data and a probabilistic generative model, Bayesian inference aims at obtaining the distribution of a model's latent parameters that could have yielded the data. This task is chall...

Scalable Bayesian Inference for Detection and Deblending in Astronomical Images

Authors: Derek Hansen, Ismael Mendoza, Runjing Liu, Ziteng Pang, Zhe Zhao, Camille Avestruz, Jeffrey Regier

arXiv

We present a new probabilistic method for detecting, deblending, and cataloging astronomical sources called the Bayesian Light Source Separator (BLISS). BLISS is based on deep generative models, which...

Bayesian estimation of in-game home team win probability for National Basketball Association games

Authors: Jason T. Maddox, Ryan Sides, Jane L. Harvill

arXiv

Maddox, et al. (2022) establish a new win probability estimation for college basketball and compared the results with previous methods of Stern (1994), Desphande and Jensen (2016) and Benz (2019). Thi...

Action potential solitons and waves in axons

Authors: Gaspar Cano, Rui Dilão

arXiv

We show that the action potential signals generated inside axons are reaction-diffusion solitons or reaction-diffusion waves, refuting the Hodgkin and Huxley hypothesis that action potentials propagat...

Application of Benford-Newcomb Law with Base Change to Electoral Fraud Detection

Authors: Eduardo Gueron, Jeronimo Pellegrini

arXiv

The invariance of Benford-Newcomb law under base changing is employed to test whether or not some data follow such distribution. Taking into account the Brazilian senate election in 1994, changes in t...

Bayesian design and analysis of two-arm cluster randomised trials using assurance

Authors: Kevin J Wilson

arXiv

We consider the design of a two-arm superiority cluster randomised controlled trial (RCT) with a continuous outcome. We detail Bayesian inference for the analysis of the trial using a linear mixed-eff...
