Categorization is fundamental to intelligence. Without categories (concepts or classes), every experience would be new, and we couldn't make sense of our world. In this talk, I will briefly go over supervised learning, in particular multiclass learning. I will then present the approach of learning a sparse feature-to-class mapping, or index learning. While our primary driver has been scalability and simplicity, we have observed that classification accuracies remain competitive or better when compared to a number of other approaches, while we obtain speed up of orders of magnitude. I will discuss applications to several tasks.
