CS 234, Winter 2012: Computational Methods for the Analysis of Biomolecular Data
An impressive wealth of data has being ammassed by genome sequencing projects and other efforts to determine the structures and functions of biological systems. This advanced graduate course will focus on a selection of computational problems aimed at automatically analyze, cluster and classify biomolecular data.
12:40 p.m. - 02:00 p.m. INTS 2134

Preliminary list of topics
overview on probability and statistics intro to molecular and computational biology analysis of 1D sequence data (DNA, RNA, proteins) Space-efficient data structures for sequences Short read mapping (suffix trees, suffix arrays, BWT) Sequence alignment and hidden Markov models (HMM) analysis of 2D data (gene expression data and graphs) clustering algorithms classification algorithms subspace clustering/bi-clustering genetic networks, co-expression networks, metabolic networks, protein-protein interaction graphs
CS141 (Algorithms) or CS218 (Design and Analysis of Algorithms) or equivalent knowledge. Some programming experience is expected. Students should have some notions of probability and statistics. No biology background is assumed.
The course will include lectures by the instructor, guest lectures, and possibly discussion sessions on special problems. Students are expected to study the material covered in class. In addition to selected chapters from some of the books listed below, there may be handouts of research papers. There will be three/four assignments, mostly of theoretical nature -- although some may require programming. The actual format of the course will ultimately depend on the number and the background of the students enrolled.
Relation to Other Courses
This course is intended to complement "CS238: Algorithms in Computational Molecular Biology", and "CS235: Data Mining Concepts".
