Research Abstract

For the first task on HCV NS5A resistance mechanisms to interferon/ribavirin therapy, our semi-supervised ensemble method discovered the motifs that well characterizing two class of patients with SVR and non-SVR, especially in case of only a small number labelled NS5A sequences but much unlabelled sequences are available. For the second task on the knockdown efficacy of siRNA, one of our method discovered two siRNA design rules in addition to known design rules, and the other significantly improve the predictive ability for given siRNA sequences. This method employs both scored and labelled sequences as well as known design rules to enrich the poor sequence representation of siRNA by transformed matrices. The prediction is done by a novel tensor regression method on those matrices. For the third task on the interplay between epigenetic factors and hepatitis progression, we reached some intermediate results such as inferring the causual relationship network of histone modifications.
