Abstract

Human Microbiome Project Laplacian regularization Metagenomics Non-negative matrix factorization
With the advance of high-throughput sequencing technology, it is possible to investigate many complex biological and ecological systems. The objective of Human Microbiome Project (HMP) is to explore the microbial diversity in our human body and to provide experimental and computational standards for subsequent similar studies. The first-stage HMP generated a lot of data for computational analysis and provided a challenge for integration and interpretation of various microbiome data. In this paper, we introduce a data integration method –Laplacian-regularized Joint Non-negative Matrix Factorization (LJ-NMF) for analyzing functional and phylogenetic profiles from HMP jointly. The experimental results indicate that the proposed method offers an efficient framework for microbiome data analysis.
