A seminar coached from the an analytics teacher into the strong generative models, technology at the rear of deepfakes that will transform a beneficial selfie into a beneficial Renaissance-build portrait. The only real boy off civil servants, Wu is actually attracted to number at an early age, majoring within the math from the Nanjing University ahead of visiting Columbia to have the girl master’s for the data science. Columbia Information talked so you can the woman in the the lady research, the lady favourite build within the statistics, and much more.

Your first project was a student in neuroscience. Tell us about this.

We oriented a beneficial generative design to explain maternal decisions for the mice. I found myself capable generate quick-name behavioral sequences that searched reasonable, however, I failed to make longer term sequences with good medical perceptions.
