I am a final year phd candidate
and a research scientist at Google DeepMind
at Berkeley EECS,
advised by Prof. Yi Ma
and Prof. Sergey Levine.
I am also affliated
Because of my advisors, I have nothing to do with it
(except for having a seat at the beautiful Berkeley Way West office).
with BAIR.
I obtained an MS degree from Columbia University with Prof. John Wright
and a BS degree in Math & Applied Math
It is only one major,
I do not know why Zhejiang University (ZJU) created a major named
"Math & Applied Math".
Perhaps ZJU is trying to suggest that some math majors are not applicable?
from Zhejiang University
Not from the Chu Kochen Honors College,
because I did pretty poorly during undergrad..
