Measure of Strength of Evidence for Visually Observed Differences between Subpopulations
Xi Yang, Jan Hannig, Katherine A. Hoadley +2
For measuring the strength of visually-observed subpopulation differences, the Population Difference Criterion is proposed to assess the statistical significance of visually observ…
Theory of high-dimensional outliers
Hyo Young Choi, J. S. Marron
This study concerns the issue of high dimensional outliers which are challenging to distinguish from inliers due to the special structure of high dimensional space. We introduce a…
Variable screening based on Gaussian Centered L-moments
Hyowon An, Kai Zhang, Hannu Oja +1
An important challenge in big data is identification of important variables. In this paper, we propose methods of discovering variables with non-standard univariate marginal distri…
Estimation of the number of spikes using a generalized spike population model and application to RNA-seq data
Hyo Young Choi, J. S. Marron
Although a generalized spike population model has been actively studied in random matrix theory, its application to real data has been rarely explored. We find that most methods fo…
Geometric Insights into Support Vector Machine Behavior using the KKT Conditions
Iain Carmichael, J. S. Marron
The support vector machine (SVM) is a powerful and widely used classification algorithm. This paper uses the Karush-Kuhn-Tucker conditions to provide rigorous mathematical proof fo…
"Virus hunting" using radial distance weighted discrimination
Jie Xiong, D. P. Dittmer, J. S. Marron
Motivated by the challenge of using DNA-seq data to identify viruses in human blood samples, we propose a novel classification algorithm called "Radial Distance Weighted Discrimina…
