Bio-relation Discovery and Sparse Learning

  • In this dissertation, I discuss several important problems in the area of bio-relation discovery (BRD). Discovering bio-relations is an important problem that arises frequently in bioinformatics. It involves identifying relationships (usually pairwise) between bio-entities. These relationships can be categorized as undirected versus directed. I will investigate both types of BRD problems in this dissertation. For undirected BRD, I will specifically discuss the gene-sample expression bi-clustering problem. For directed BRD, I will focus on problems in gene regulatory network inference and drug-target network inference. For all these problems I have investigated both heuristic approaches and sparse learning based approaches from machine learning.
