PhD Seminar • Computer Graphics — Constructing Smooth Surfaces with Continuous Curvatures for Triangular Scattered Data

Please note: This PhD seminar will be given online.

Xiang Fang, PhD candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Stephen Mann

A new set of schemes are designed to create smooth surfaces with continuous curvatures or higher order continuity for triangular scattered data sites, without complex computation.

Seminar • Machine Learning — Steps Towards Making Machine Learning More Natural

Please note: This seminar will be given online.

Mengye Ren, Department of Computer Science
University of Toronto

Over the past decades, we have seen machine learning making great strides in AI applications. Yet, most of its success relies on training models offline on a massive amount of data and evaluating them in a similar test environment. By contrast, humans can learn new concepts and skills with very few examples, and can easily generalize to novel tasks.

PhD Seminar • Algorithms and Complexity — Geodesic Convexity in Statistics and Sample Complexity Bounds

Please note: This PhD seminar will be given online.

Akshay Ramachandran, PhD candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Lap Chi Lau

The matrix normal model, the family of Gaussian matrix-variate distributions whose covariance matrix is the Kronecker product of two lower dimensional factors, is frequently used to model matrix-variate data. The tensor normal model generalizes this family to Kronecker products of three or more factors.

Seminar • Cryptography, Security, and Privacy (CrySP) — Measuring and Enhancing the Security of Machine Learning

Please note: This seminar will be given online.

Florian Tramèr, Computer Science Department
Stanford University

Failures of machine learning systems can threaten both the security and privacy of their users. My research studies these failures from an adversarial perspective, by building new attacks that highlight critical vulnerabilities in the machine learning pipeline, and designing new defenses that protect users against identified threats.

Seminar • Systems and Networking — Resource-Efficient Execution for Deep Learning

Please note: This seminar will be given online.

Deepak Narayanan, Department of Computer Science
Stanford University

Deep Learning models have enabled state-of-the-art results across a broad range of applications; however, training these models is extremely time- and resource-intensive, taking weeks on clusters with thousands of expensive accelerators in the extreme case.
