Lili Mou is currently a postdoctoral fellow at the University of Waterloo. Lili received his BS and PhD degrees in 2012 and 2017, respectively, from School of EECS, Peking University. After that, he worked as a postdoctoral fellow at the University of Waterloo and a research scientist at Adeptmind (a startup in Toronto, Canada). His research interests include deep learning applied to natural language processing as well as programming language processing. He has publications at top conferences and journals like AAAI, ACL, CIKM, COLING, EMNLP, ICASSP, ICML, IJCAI, INTERSPEECH, NAACL-HLT, and TACL (in alphabetic order). [CV]

Seminars

In our seminars, we discuss machine learning theories, algorithms,
and applications (with special interest in NLP). We start from the foundations,
and move to the frontiers.
