Research

Self-supervised Learning

I engineer and align representations in deep learning models. Key aspects of my work include leveraging representation quality metrics and invariance properties of features for learning. I apply these techniques to create more interpretable and controllable models.

Reinforcement Learning

My research covers model-based reinforcement learning, focusing on partially observable Markov decision processes and multi-armed bandits. My work includes novelty detection, information gathering, and curriculum learning to enhance learning efficacy.

Autonomous Driving

I have worked extensively on the research and engineering of autonomous driving systems. I applied my machine learning research to autonomous driving and have also developed rule-based algorithms that run in real-time on autonomous car prototypes.
