Abstract

A vast amount of research has been conducted in this area of supervised learning, specifically addressing various classification problems such as binary, multi-class and multi-label classification. However, in the real world we encounter classification problems where multiple tasks share complex interdependencies between them (e.g., hierarchies). Methods that are able to take advantage of the additional information regarding task relationships and interactions are able to perform better in terms of classification accuracy. Furthermore, with the vast amount of data that is being accumulated in the recent years the real world problems that have any practical utility have exploded in terms of problem size; with respect to number of data elements, feature size and number of class labels. Therefore, there is an urgent need for scalable methods that are able to gracefully scale to such problems. In this talk, I specifically discuss novel classification methods for large scale hierarchical classification and multi-task learning.
