Iterative execution of discrete and inverse discrete Fourier transforms with applications for signal denoising via sparsification
H. Robert Frost
We describe a family of iterative algorithms that involve the repeated execution of discrete and inverse discrete Fourier transforms. One interesting member of this family is motiv…
Eigenvectors from Eigenvalues Sparse Principal Component Analysis (EESPCA)
H. Robert Frost
We present a novel technique for sparse principal component analysis. This method, named Eigenvectors from Eigenvalues Sparse Principal Component Analysis (EESPCA), is based on the…
A Semiparametric Joint Model for Terminal Trend of Quality of Life and Survival in Palliative Care Research
Zhigang Li, H. R. Frost, Tor D. Tosteson +7
Palliative medicine is an interdisciplinary specialty focusing on improving quality of life (QOL) for patients with serious illness and their families. Palliative care programs are…
Spectral gene set enrichment (SGSE)
H. Robert Frost, Zhigang Li, Jason H. Moore
Motivation: Gene set testing is typically performed in a supervised context to quantify the association between groups of genes and a clinical phenotype. In many cases, however, a…
Principal component gene set enrichment (PCGSE)
H. Robert Frost, Zhigang Li, Jason H. Moore
Motivation: Although principal component analysis (PCA) is widely used for the dimensional reduction of biomedical data, interpretation of PCA results remains daunting. Most existi…
