AN IMPROVED SUPERVISED RANKING STRATEGY FOR FUNCTIONAL PRINCIPAL COMPONENTS IN HYPERSPECTRAL IMAGING

Unlike conventional imaging systems, which capture data in discrete RGB channels, hyperspectral imaging (HSI) technology provides detailed spectral information across a continuous wavelength range. Analyzing HSI data presents a challenge due to its infinite-dimensional feature space and relatively limited sample size....

Refining scRNA-Seq Clusters: The Power of Feature Selection

Feature selection is critical for resolving cell-type heterogeneity in single-cell RNA sequencing (scRNA-seq). DUBStepR (Determining the Underlying Basis using Stepwise Regression) is a widely used gene selection method for scRNA-seq designed to identify feature genes that maximize cell-type separation. DUBStepR has be...
