Gradient-flow adaptive importance sampling for Bayesian leave one out cross-validation for sigmoidal classification models

no code implementations13 Feb 2024 Joshua C Chang, Xiangting Li, Shixin Xu, Hao-Ren Yao, Julia Porcino, Carson Chow

We introduce a set of gradient-flow-guided adaptive importance sampling (IS) transformations to stabilize Monte-Carlo approximations of point-wise leave one out cross-validated (LOO) predictions for Bayesian classification models.

Self-supervised Representation Learning on Electronic Health Records with Graph Kernel Infomax

no code implementations1 Sep 2022 Hao-Ren Yao, Nairen Cao, Katina Russell, Der-Chen Chang, Ophir Frieder, Jeremy Fineman

We propose Graph Kernel Infomax, a self-supervised graph kernel learning approach on the graphical representation of EHR, to overcome the previous problems.

The Analysis from Nonlinear Distance Metric to Kernel-based Drug Prescription Prediction System

no code implementations4 Feb 2021 Der-Chen Chang, Ophir Frieder, Chi-Feng Hung, Hao-Ren Yao

Distance metrics and their nonlinear variant play a crucial role in machine learning based real-world problem solving.

Cross-Global Attention Graph Kernel Network Prediction of Drug Prescription

no code implementations4 Aug 2020 Hao-Ren Yao, Der-Chen Chang, Ophir Frieder, Wendy Huang, I-Chia Liang, Chi-Feng Hung

We present an end-to-end, interpretable, deep-learning architecture to learn a graph kernel that predicts the outcome of chronic disease drug prescription.
