"Unusual Motifs in Biological Data "
Thursday September 30, 2004 04:00 PM
Location: Conference Room (2nd Floor), Toxicology Building NCSU Centennial Campus
(Visitor parking instructions)
This talk is part of the Bioinformatics Seminar Series
The talk will focus on various kinds of patterns in data that we identify and devise methods for unsupervised (automatic) discovery. We will particularly discuss two kinds of patterns (1) permutation motifs, and (2) cluster motifs. We will define the problems, present a non-statistical (or model-less) method of pruning the data. We will show the relationship between permutation motifs and a well known data structure in computer science (PQ Trees) and demonstrate its potential on man-rat data. We will also briefly discuss the work on cluster motifs in protein simulation data to extract state-to-state transitions.
