Explainable Censored Learning: Finding Critical Features with Long Term Prognostic Values for Survival Prediction

no code implementations30 Sep 2022 Xinxing Wu, Chong Peng, Richard Charnigo, Qiang Cheng

Interpreting critical variables involved in complex biological processes related to survival time can help understand prediction from survival models, evaluate treatment efficacy, and develop new therapies for patients.

PRIME: Uncovering Circadian Oscillation Patterns and Associations with AD in Untimed Genome-wide Gene Expression across Multiple Brain Regions

1 code implementation25 Aug 2022 Xinxing Wu, Chong Peng, Gregory Jicha, Donna Wilcock, Qiang Cheng

Then, we apply it to study oscillation patterns in untimed genome-wide gene expression from 19 human brain regions of controls and AD patients.

On the algebraic structures of the space of interval-valued intuitionistic fuzzy numbers

no code implementations1 Dec 2021 Xinxing Wu, Chaoyue Tan, Gul Deniz Cayli, Peide Liu

In this study, we prove that the space of all IVIFNs with the relation in the method for comparing any two IVIFNs based on a score function and three types of entropy functions is a complete chain and obtain that this relation is an admissible order.

Topological and Algebraic Structures of Atanassov's Intuitionistic Fuzzy-Values Space

no code implementations17 Nov 2021 Xinxing Wu, Tao Wang, Qian Liu, Peide Liu, Guanrong Chen, Xu Zhang

By introducing a new operator for IFVs via the linear order based on a score function and an accuracy function, we show that such an operator is a strong negation on IFVs.
