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

Three enhancements are presented in this study: RFCell-DUBStepR, which uses random forests to capture expression-level importance; Copula-DUBStepR, which models non-linear correlations via Gaussian Copulas; and Zqt-DUBStepR, which utilizes quantile-based selection for improved gene retention.
