Sparse Generalized Eigenvalue Problem with Application to Canonical Correlation Analysis for Integrative Analysis of Methylation and Gene Expression Data
Sandra E. Safo, Jeongyoun Ahn, Yongho Jeon +1
We present a method for individual and integrative analysis of high dimension, low sample size data that capitalizes on the recurring theme in multivariate analysis of projecting h…
Inference on subspheres model for directional data
Sungkyu Jung
Modeling deformations of a real object is an important task in computer vision, biomedical engineering and biomechanics. In this paper, we focus on a situation where a three-dimens…
Continuum directions for supervised dimension reduction
Sungkyu Jung
Dimension reduction of multivariate data supervised by auxiliary information is considered. A series of basis for dimension reduction is obtained as minimizers of a novel criterion…
Combined Analysis of Amplitude and Phase Variations in Functional Data
Sungwon Lee, Sungkyu Jung
When functional data manifest amplitude and phase variations, a commonly-employed framework for analyzing them is to take away the phase variation through a function alignment and…
Geometric foundations for scaling-rotation statistics on symmetric positive definite matrices: minimal smooth scaling-rotation curves in low dimensions
David Groisser, Sungkyu Jung, Armin Schwartzman
We investigate a geometric computational framework, called the "scaling-rotation framework", on , the set of symmetric positive-definite (SPD) matrices…
