TL;DR

A novel characteristic of dataset heterogeneity is introduced by employing the norm of the difference between the maximum and minimum points in the classical terms of functional analysis.

Abstract

In this paper, we consider methods for the diagonal multi-omics integration of heterogeneous datasets. Several approaches to the nature of biological heterogeneity are analyzed and developed to comprehend more clearly the generated differences. Specifically, the extremal trace problems for the coupled Laplacian on sets homeomorphic to the Stiefel manifold embedded in the complex Euclidean space are investigated. The gradient ascent method for the maximization problem is elaborated in the classical terms of functional analysis, which is of significant interest in itself. On this basis, we introduce a novel characteristic of dataset heterogeneity by employing the norm of the difference between the maximum and minimum points.

Semi-supervised Omics Factor Analysis (SOFA) disentangles known and latent sources of variation in multi-omic data

A fundamental design pattern in biomolecular studies is to assay the same set of samples (organisms, tissue biopsies, or individual cells) by multiple different ‘omics assays. Group Factor Analysis (GFA) and its adaptation to high-dimensional settings, Multi-Omics Factor Analysis (MOFA), are widely used as a first-line...

MT-LLE: Multi-task locally linear embedding for interpretable disease modeling from longitudinal omics data

Constructing interpretable disease models from longitudinal omics data is a central challenge in precision medicine. The goal is a low-dimensional representation in which a patient’s position encodes their molecular state and clinical severity, and along which disease progression can be read directly. Existing dimensio...
