Master’s Thesis Presentation • Cryptography, Security, and Privacy (CrySP) • Unbiased Statistical Estimation and Valid Confidence Intervals Under Differential Privacy

Please note: This master’s thesis presentation will be given online.

Christian Covington, Master’s candidate
David R. Cheriton School of Computer Science

Supervisors: Professors Xi He, Gautam Kamath

Friday, June 24, 2022 1:00 pm - 2:00 pm EDT (GMT -04:00)

PhD Seminar • Machine Learning • Out-of-distribution Detection with Flow Generative Models

Please note: This PhD seminar will be given online.

Dihong Jiang, PhD candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Yaoliang Yu

Out-of-distribution (OOD) data come from a distribution that is different from training data. Detecting OOD data contributes to secure deployment of machine learning models. Currently, deep generative models have been widely used as an unsupervised approach for OOD detection.

Supervisor: Professor N. Asokan

Deep reinforcement learning (DRL) has seen many successes in complex tasks such as robot manipulation, autonomous driving, and competitive games. However, there are few studies on the security threats against DRL systems. In this thesis, we focus on two security concerns in DRL.
