Density-based Isometric Mapping for Precision Medicine
The author introduces a novel method, PR-Isomap, to project high-dimensional data into a lower-dimensional space while preserving both local and global distances. By modifying the Isomap algorithm with a Parzen-Rosenblatt constraint, the approach aims to enhance uniformity and maintain geodesic distance approximation.
DiffRed: Dimensionality Reduction Guided by Stable Rank
DiffRed introduces a novel approach to dimensionality reduction guided by stable rank, achieving tighter bounds on M1 and Stress metrics. The algorithm leverages stable rank to optimize the target dimensions for reduced distortion.
