Building Advanced Learning Algorithms and AI Systems

Through rigorous theoretical foundations and principled algorithm design

My research explores the overlap between practical machine-learning methods and their underlying theory, a space where recent progress in training deep networks still depends largely on heuristics and has little theoretical backing. I aim to narrow the gap between theory and practice by:
1Explain

developing practical theory that explains why specific phenomena arise and why certain heuristics succeed during deep-learning training

2Improve

advancing existing algorithms from first principles

3Create

creating new scalable and efficient methods with both theoretical analysis and practical performance
