John Hewitt

Hello! I’m a second-year PhD student in computer science, conducting research in natural language processing at Stanford University. I am grateful to be co-advised by Chris Manning and Percy Liang.

I design and analyze machine learning models of human languages. I’m broadly interested in (interpreting) representation learning, induction of latent hierarchical structure, settings with small data, and multilinguality.

As an undergraduate at Penn, I worked in the lab of Chris Callison-Burch.

Feel free to look me up on Google Scholar or Twitter, or take my CV.

    The Fundamental Whiteboard Difficulty (Scott Aaronson):

    I figured that chalk has its problems—it breaks, the dust gets all over—but I could live with them, much more than I could live with the Fundamental Whiteboard Difficulty, of all the available markers always being dry whenever you want to explain anything.

    I highly suggest Arch Linux for its configurability and the educational experience it provides…
