Algorithmic Stability and Generalization of an Unsupervised Feature Selection Algorithm
Xinxing Wu, Qiang Cheng
Feature selection, as a vital dimension reduction technique, reduces data dimension by identifying an essential subset of input features, which can facilitate interpretable insight…
Topological dynamics of Zadeh's extension on the space of upper semi-continuous fuzzy sets
Xinxing Wu, Xiong Wang
In this paper, some characterizations about transitivity, mildly mixing property, -transitivity, equicontinuity, uniform rigidity and proximality of Zadeh's extensions…
Shadowing and metric expansivity on Fréchet spaces
Xinxing Wu, Guting Wang
We prove that (1) the weighted composition operator \(Tf(z)=c f(Bz)\) on the Fréchet space \(H(\mathbb{C}^d)\) of entire functions on \(\mathbb{C}^d\) (\(d\in\mathbb{N}\)) with th…
The conformable fractional grey system model
Xin Ma, Wenqing Wu, Bo Zeng +2
The fractional order grey models (FGM) have appealed considerable interest of research in recent years due to its higher effectiveness and flexibility than the conventional grey mo…
Designing Singing Syllabi with Virtual Avatars: AI-Assisted Syllabus Reauthoring
Xinxing Wu
Traditional syllabi often function as static reference documents rather than engaging introductions to a course. In practical teaching, we observe that few students thoroughly read…
Alcohol Intake Differentiates AD and LATE: A Telltale Lifestyle from Two Large-Scale Datasets
Xinxing Wu, Chong Peng, Peter T. Nelson +1
Alzheimer's disease (AD), as a progressive brain disease, affects cognition, memory, and behavior. Similarly, limbic-predominant age-related TDP-43 encephalopathy (LATE) is a recen…
