Christopher Manning: Linguistics and the Development of NLP

Have suggestions for future podcast guests (or other feedback)? Let us know here!

In episode 41 of The Gradient Podcast, Daniel Bashir speaks to Christopher Manning.

Chris is the Director of the Stanford AI Lab and an Associate Director of the Stanford Human-Centered Artificial Intelligence Institute. He is an ACM Fellow, an AAAI Fellow, and past President of ACL. His work currently focuses on applying deep learning to natural language processing; it has included tree recursive neural networks, GloVe, neural machine translation, and computational linguistic approaches to parsing, among other topics.
