Biography
Hi! I am Wenyan, a second-year PhD student at the CoAStaL NLP Group, University of Copenhagen. I’m supervised by Anders Søgaard and Desmond Elliott.
Before this, I worked as a Senior NLP Researcher at Sensetime and Comcast AI Research Lab (mentored by Ferhan Ture).
I completed my MS at University of Maryland, College Park, where I worked with Prof. Jordan Boyd-Graber on Natural Language Processing.
In my free time, I enjoy painting, cooking, yoga, and table tennis :)

Experience
Senior NLP Researcher (Artificial General Intelligence team)
- Knowledge-enhanced QA and dialogue system * Multimodal and prompt learning
Senior Machine Learning Research Engineer (NLP)
- Designed an unsupervised auto-annotation system for voice queries with user behavioral modeling to automatically identify errors in speech recognition and NLP systems and suggest corrections
- Built an active learning pipeline with auto-labeled user transcriptions to improve ASR system for comcast X1, increasing system recognition accuracy by 9% (summarized the work into a conference paper as the first-author and filed a patent as the main inventor)
- Developed a context-based approach that discovered misclassified user queries in question answering systems by performing semantic search with Sentence-BERT
- Leveraged subword-level query representation and adversarial training in customer care dialogue system for misspelled user queries, which improved classification accuracy by 18% and increased user experience stability
- Mentored interns and new-hires on projects relevant to multi-task learning and query representation
