I'm a MS/BS student at Stanford with a concentration in machine learning and a minor in creative writing. I'm interested in shaping datasets to make machine deep learning more accesible in domains like computer vision and medical imaging.

I'm currently a research assistant in the Stanford AI Lab with Chris Ré's group. Most recently, I've been training neural networks on the Autopilot vision team at Tesla. In the past, I worked at Sift Science to fight fraud with machine learning, Xbox to build VR experiences, and EMGuidance to build point-of-care healthcare tools. At Stanford, I had a lot of fun co-directing TreeHacks, Stanford's largest intercollegiate hackathon.

I also love reading, writing, and photography!

Predicting Wealth in NYC from FourSquare Check-ins

Vincent Chen*, Dan Yu*. CS229.

We develop a new method to predict demographics based on FourSquare data by engineering features based on check-ins mapped to U.S. census tracts.

Class-conditional Superresolution with GANs

Vincent Chen*, Liezl Puzon*, Christina Wadsworth*. CS231N.

We propose several methods to introduce auxiliary, conditional information into generative adversarial networks (GANs) that produce super-resolution results that better tuned to the human eye.

Sequence-to-Sequence Text Summarization

Vincent Chen*, Liezl Puzon*, Eduardo Torres Montaño*. Advisor: Danqi Chen. CS224N.

We implement several approaches for sequence-to-sequence summarization on the CNN/DailyMail dataset using attention mechanisms and pointer networks.
