Grouped integrative dynamic factor models for intra-and inter- individual brain networks Abstract: We introduce a novel framework for dynamic factor model-based data integration of multiple subjects, Grouped Integrative Dynamic factor models (GRIDY). This work is a pilot study to suggest … Read more

Convergence of Gaussian kernelized graph Laplacian: eigen-convergence and bi-stochastic normalization Consider kernelized graph affinity matrix constructed from $N$ data points i.i.d. sampled from a general unknown $d$-dimensional manifold embedded in a possibly high-dimensional space. The setting is generic in graph-based … Read more
Title: Graph representation learning for single-cell genomics Abstract: Single-cell RNA sequencing measures gene expression at an unprecedented resolution and scale and allows the analysis of cellular phenotypes which was not possible before. In this context, graphs occur as a natural … Read more
