Computer Science Seminar: Hui Guan

This event is open to all Illinois Tech students and faculty. 

Abstract

Modern machine learning, especially deep learning, faces a fundamental question: How to create models that efficiently deliver reliable predictions to meet the requirements of diverse applications running on various systems. This talk will introduce reuse-centric optimization, a novel direction for addressing the fundamental question. Reuse-centric optimization centers around harnessing reuse opportunities for enhancing computing efficiency. It generalizes the principle to a higher level and a larger scope through a synergy between programming systems and machine-learning algorithms. Its exploitation of computation reuse spans across the boundaries of machine-learning algorithms, implementations, and infrastructures; the types of reuse it covers range from pre-trained neural network building blocks to preprocessed results and even memory bits; the scopes of reuse it leverages go from training pipelines of deep learning to variants of neural networks in ensembles; and the benefits it generates extend from orders of magnitude faster search for a good smaller convolution neural network (CNN) to the elimination of all space cost in protecting parameters of CNNs.
