Hi! I’m a PhD student working with Dhruv Batra at Georgia Tech. I try to understand Neural Networks, especially as applied to Computer Vision. As deep networks become more widely used, I hope to find new ways for users to understand the complex systems they use and to leverage this understanding to build better models.
