Most of the methods statistically evaluate whether the expression profiles of each gene set are fit to assumed models: e.g. co-expression across all samples or a subgroup of samples. However, it is possible that they fail to capture informative gene sets whose expression profiles are not fit to the assumed models.<\/jats:p>\n               <jats:p>Results: To overcome this limitation, we propose a model-free unsupervised gene set screening method, Matrix Information Enrichment Analysis (MIEA). Without assuming any specific models, MIEA screens gene sets based on information richness of their expression profiles. We extensively compared the performance of MIEA to those of other unsupervised gene set screening methods, using various types of simulated and real data. The benchmark tests demonstrated that MIEA can detect singular expression profiles that the other methods fail to find, and performs broadly well for various types of input data. Taken together, this study introduces MIEA as a broadly applicable gene set screening tool for mining regulatory programs from transcriptome data.<\/jats:p>\n               <jats:p>Contact: \u00a0aniida@ims.u-tokyo.ac.jp<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btq592","type":"journal-article","created":{"date-parts":[[2010,10,20]],"date-time":"2010-10-20T00:59:01Z","timestamp":1287536341000},"page":"3090-3097","source":"Crossref","is-referenced-by-count":1,"title":["Model-free unsupervised gene set screening based on information enrichment in expression profiles"],"prefix":"10.1093","volume":"26","author":[{"given":"Atushi","family":"Niida","sequence":"first","affiliation":[{"name":"1 Human Genome Center, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639 and 2Computational Science Research Program, RIKEN, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seiya","family":"Imoto","sequence":"additional","affiliation":[{"name":"1 Human Genome Center, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639 and 2Computational Science Research Program, RIKEN, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rui","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"1 Human Genome Center, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639 and 2Computational Science Research Program, RIKEN, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masao","family":"Nagasaki","sequence":"additional","affiliation":[{"name":"1 Human Genome Center, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639 and 2Computational Science Research Program, RIKEN, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9","family":"Fujita","sequence":"additional","affiliation":[{"name":"1 Human Genome Center, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639 and 2Computational Science Research Program, RIKEN, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teppei","family":"Shimamura","sequence":"additional","affiliation":[{"name":"1 Human Genome Center, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639 and 2Computational Science Research Program, RIKEN, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoru","family":"Miyano","sequence":"additional","affiliation":[{"name":"1 Human Genome Center, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639 and 2Computational Science Research Program, RIKEN, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2010,10,19]]},"reference":[{"key":"2023012508033673300_B1","doi-asserted-by":"crossref","first-page":"031902","DOI":"10.1103\/PhysRevE.67.031902","article-title":"Iterative signature algorithm for the analysis of large-scale gene expression data","volume":"67","author":"Bergmann","year":"2003","journal-title":"Phys.
