I am Zihan (Johan) Liu (刘子涵). I received Bachelor Degree from Zhejiang University. Currently, I am a Ph.D. candidate at Department of Electronic and Computer Engineering, The Hong Kong University of Science and Technology supervised by Prof. Pascale Fung in Center of AI Research.

1. ← Select a category and a module group on the left to get a list of modules. Drag a module to the layout to see its stats and show the total of the entire layout.
2. Slot-filling subtasks: Assume nslot-filling sub-tasks fS 1;S 2:::S ng. We set up each slot-filling sub-task S i as a supervised binary classification prob-lem. Given the tweet tand the candidate slot s, the model f(t;s)!f0;1gpredicts whether san-swers its designated question. We extract a list of 3https://developer.twitter.com/.

My current research interests are cross-lingual adaptation, cross-domain adaptation, few-shot learning, and dialogue systems.

Decomposition of open-vocabulary dialog state tracking to state operation prediction and slot value generation, achieving excellent joint goal accuracy with very efficient computation - ACL 2020 Sungdong Kim, Sohee Yang, Gyuwan Kim, and Sang-Woo Lee.
