COMP_SCI 496: Generative Deep Models

Quarter Offered

Spring : 4-6:50 W ; Pardo

Prerequisites

Registration is by instructor permission only. Students should contact mailto:pardo@northwestern.edu if they are interested in taking the class. Note: Prior experience with the algorithms underlying machine learning (and especially deep learning) is necessary. Example prior coursework includes Prof. Han Liu’s Statistical Machine Learning course and Prof. Bryan Pardo’s Deep Learning course. This course is designed for doctoral students. Appropriately prepared BS and MS students may also be admitted, once doctoral student demand has been met.

Description

Deep learning is a branch of machine learning based on algorithms that try to model high-level abstract representations of data by using multiple processing layers with complex structures. One of the most exciting areas of research in deep learning is that of generative models. Today’s generative models create text documents, write songs, make paintings and videos, and generate speech. This course is dedicated to understanding the inner workings of the technologies that underlie these advances. Students will learn about key methodologies, including Variational Autoencoders (VAEs), Generative Adversarial Networks (GANs), and Transformer-based language models.  This is an advanced course that presumes a good working understanding of traditional supervised neural network technology and techniques (e.g. convolutional networks, LSTMs, loss functions, regularization, gradient descent).

REQUIRED TEXTBOOK: Advanced research papers in the field.

REFERENCE TEXTBOOKS: (not required purchases) The focus will be on research papers published in the field.

COURSE COORDINATOR: Prof. Bryan Pardo

COURSE GOALS: The goal of this course is to familiarize graduate students (and advanced undergraduates) with the current state-of-the-art in machine generation of speech, music, still images and video using Deep Learning architectures. Students will read recently published papers in the field and become well informed on at least one sub-field within this area.
