Hypothesis Testing for Detecting Outlier Evaluators

Authors: Li Xu, Molin Wang

arXiv

In epidemiological studies, very often, evaluators obtain measurements of disease outcomes for study participants. In this paper, we propose a two-stage procedure for detecting outlier evaluators. In...

Adapting Brain-Like Neural Networks for Modeling Cortical Visual Prostheses

Authors: Jacob Granley, Alexander Riedel, Michael Beyeler

arXiv

Cortical prostheses are devices implanted in the visual cortex that attempt to restore lost vision by electrically stimulating neurons. Currently, the vision provided by these devices is limited, and...

Feature detection and hypothesis testing for extremely noisy nanoparticle images using topological data analysis

Authors: Andrew M. Thomas, Peter A. Crozier, Yuchen Xu, David S. Matteson

arXiv

We propose a flexible algorithm for feature detection and hypothesis testing in images with ultra low signal-to-noise ratio using cubical persistent homology. Our main application is in the identifica...

Tree Representations of Brain Structural Connectivity via Persistent Homology

Authors: Didong Li, Phuc Nguyen, Zhengwu Zhang, David B Dunson

arXiv

The brain structural connectome is generated by a collection of white matter fiber bundles constructed from diffusion weighted MRI (dMRI), acting as highways for neural activity. There has been abunda...

Interpretable estimation of the risk of heart failure hospitalization from a 30-second electrocardiogram

Authors: Sergio GonzĂĄlez, Wan-Ting Hsieh, Davide Burba, Trista Pei-Chun Chen, Chun-Li Wang, Victor Chien-Chia Wu, Shang-Hung Chang

arXiv

Survival modeling in healthcare relies on explainable statistical models; yet, their underlying assumptions are often simplistic and, thus, unrealistic. Machine learning models can estimate more compl...
