About me

I am Dinghuai Zhang (张鼎怀), a third year PhD student at Mila. I belong to Prof. Bengio’s group as well as Aaron’s Army (aka A.A.). I am also honored to have the opportunity to be mentored by Dr. Tian Qi Chen at FAIR labs. Previously, I was an undergraduate in School of Mathematical Sciences at Peking University, working with Prof. Zhanxing Zhu and Prof. Bin Dong.

I am always open to possible cooperation or visiting opportunities. If you are interested, please contact me by email or wechat.

Research interests

  • Causal inference & out-of-distribution generalization (invariant prediction, adversarial robustness).
  • Uncertainty (Bayesian inference, conformal inference) & generative models.
  • Exploration with structure (RL, active learning).

Miscs

  • I enjoy books on sociology. I read about wisemen such as Georg Simmel, Norbert Elias, Max Weber, Sigmund Freud, blabla.
  • I love street photography. I used to be a huge fan of Daido Moriyama and Henri Cartier-Bresson.
  • I paint Chinese calligraphy well since a child.
