Clustering, multicollinearity, and singular vectors
Hamid Usefi
Let be a matrix with its pseudo-matrix and set . We prove that, after re-ordering the columns of , the matrix has a block-diagonal form w…
Detecting ulcerative colitis from colon samples using efficient feature selection and machine learning
Hanieh Marvi Khorasani, Hamid Usefi, Lourdes Peña-Castillo
Ulcerative colitis (UC) is one of the most common forms of inflammatory bowel disease (IBD) characterized by inflammation of the mucosal layer of the colon. Diagnosis of UC is base…
Solvability of Poisson algebras

Let be a Poisson algebra with a Lie bracket over a field $\F$ of characteristic . In this paper, the Lie structure of is investigated. In particular, if $…
High-Dimensional Feature Selection for Genomic Datasets
Majid Afshar, Hamid Usefi
A central problem in machine learning and pattern recognition is the process of recognizing the most important features. In this paper, we provide a new feature selection method (D…
