I plan to hire multiple PhD/MS students at UWaterloo, home to 5 NLP professors! The official deadline has passed, but if you need more time to submit your application, please send me an email. Strong consideration will be given to those who can tackle the below challenge: Can we use LM's hidden states to reason multiple problems simultaneously? See this picture for details.

My research philosophy is to "build AIs for machines": since machines and humans have different characteristics, the ways humans solve problems might not necessarily be optimal for machines. For example, humans communicate using language, but there might be more effective ways of communication between machines than human language. Therefore, in the near future, I plan to study communication and cooperation among multiple models (aka agents):

• Communication among Models: I plan to learn a communication language between models that is more effective than human language (such as continuous vectors or discrete semantic representations).
• Division of labor and cooperation: Unlike the current practice of training a single all-capable large model, I plan to train a group of small specialized models with different capabilities to complete tasks through communication and cooperation.

I also work on open-source projects such as OpenNMT, Im2LaTeX, LaTeX2Im, and Steganography to make my research efforts more readily available for developers and researchers.
