Congratulations Dr. Xu!

Congratulations to Weilin Xu for successfully defending his PhD Thesis! Weilin's Committee: Homa Alemzadeh, Yanjun Qi, Patrick McDaniel (on screen), David Evans, Vicente Ordóñez Román Improving Robustness of Machine Learning Models using Domain Knowledge Although machine learning techniques have achieved great success in many areas, such as computer vision, natural language processing, and computer security, recent studies have shown that they are not robust under attack. A motivated adversary is often able to craft input samples that force a machine learning model to produce incorrect predictions, even if the target model achieves high accuracy on normal test inputs.
