IDS 576 Advanced Predictive Models and Applications for Business Analytics

Edition: Spring 2018

Document version: Apr 26 2018

Overview

The goal of this class is to cover advanced machine learning techniques not covered in IDS 572 and IDS 575. Broadly, we will cover topics spanning graphical models and deep learning. Graphical models are a set of very useful techniques for inferring outcomes and making predictions conditional on preceding events, even when we do not have full information. They have found success in tracking, speech recognition, language modeling (Hidden Markov Models), image segmentation (Markov Random Fields) and many other applications. Similarly, we will study the basics of deep learning architectures, their design choices and how they are trained using gradient methods. We will also study recurrent and convolutional architectures which achieve state of the art in challenging prediction tasks in computer vision and text applications. Time permitting, we will also look at online and reinforcement learning problems.
