CS 260-001, Winter 2003: Pattern Discovery in Biosequences
A staggering wealth of data has being generated by genome sequencing projects and other efforts to determine the structures and functions of biological systems. This seminar course will focus on a selection of computational problems aimed at automatically analyze, cluster and classify biomolecular data.
TR 11:10am-12:30pm, SURGE 349
WF 4:30pm-5:30pm, SURGE 320
Preliminary list of topics
Overview on probability and statistics (2 lectures), introduction to molecular and computational biology (3 lectures), pattern discovery and machine learning (2 lectures), enumerative algorithms for pattern discovery (4 lectures), hidden Markov models and other statistical methods (e.g, Gibbs sampler, EM) for pattern discovery (3 lectures). There may be guest lectures and discussion sessions on special problems. The actual selection of topics may be guided by the interests of the participants.
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, class discussions, and presentations by the students. The actual format will depend on the class size and the background of the students enrolled.
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 two to three assignments, mostly of theoretical nature -- although some may require programming. At the end of the course, students are required to give a presentation on a research topic selected from a list provided by the instructor. Original projects or proposals will be taken into consideration.
Relation to Other Courses
This seminar course is intended to complement the seminar course on "Algorithms in Computational Molecular Biology" previously taught by Prof.T.Jiang, and "CS235:Data Mining Concepts" usually thought by Prof.D.Gunopulos.
