• I am looking for a PhD position in machine learning / statistic learning starting from fall, 2019. If you are interested in working with me, please do not hesitate to contact me.
• Our paper "Tangent-Normal Adversarial Regularization for Semi-supervised Learning" is accepted as an oral presentation by CVPR-2019!

I'm interested in both the theoretical and applied parts of machine learning. Specifically, I am following cutting edge researches in: 1) theoretically machine learning analysis, 2) generative models and latent variable models, 3) adversarial learning, 4) semi-supervised learning, 5) applications in computer vision.

Tangent-Normal Adversarial Regularization for Semi-supervised Learning
