Incorporating structured assumptions with probabilistic graphical models in fMRI data analysis

no code implementations11 May 2020 Ming Bo Cai, Michael Shvartsman, Anqi Wu, Hejia Zhang, Xia Zhu

With the wide adoption of functional magnetic resonance imaging (fMRI) by cognitive neuroscience researchers, large volumes of brain imaging data have been accumulated in recent years.

PipeNet: Selective Modal Pipeline of Fusion Network for Multi-Modal Face Anti-Spoofing

1 code implementation24 Apr 2020 Qing Yang, Xia Zhu, Jong-Kae Fwu, Yun Ye, Ganmei You, Yuan Zhu

Face anti-spoofing has become an increasingly important and critical security feature for authentication systems, due to rampant and easily launchable presentation attacks.

Channel Pruning via Optimal Thresholding

1 code implementation10 Mar 2020 Yun Ye, Ganmei You, Jong-Kae Fwu, Xia Zhu, Qing Yang, Yuan Zhu

By using OT, most negligible or unimportant channels are pruned to achieve high sparsity while minimizing performance degradation.

Segmenting Brain Tumors with Symmetry

no code implementations17 Nov 2017 Hejia Zhang, Xia Zhu, Theodore L. Willke

We explore encoding brain symmetry into a neural network for a brain tumor segmentation task.

A Searchlight Factor Model Approach for Locating Shared Information in Multi-Subject fMRI Analysis

no code implementations29 Sep 2016 Hejia Zhang, Po-Hsuan Chen, Janice Chen, Xia Zhu, Javier S. Turek, Theodore L. Willke, Uri Hasson, Peter J. Ramadge

In this work, we examine a searchlight based shared response model to identify shared information in small contiguous regions (searchlights) across the whole brain.
