Zhuochun Li 「李卓淳」
Welcome!
I am a second-year PhD student at the University of Pittsburgh (UPitt), majoring in Information Science. I received my M.S. in Information Science from Pitt in 2022, and my B.S. in Computer Science in 2020. I am involved in the iRiS Lab at Pitt, mentored by Prof. Daqing He.
Research interests: My research interests include Natural Language Processing (NLP), Information Retrieval, and Machine Learning.
Projects
-
[Mar 2024] PhD Preliminary Exam Project
Introduced a novel Fault-Aware DistIllation via Peer-Review (FAIR) approach that enables student LLM to better acquire reasoning skills from multiple teacher LLMs Chatgpt, Gemini, and Mistral. Helped student LM learn not only from the gold-standard rationale but also from feedback on their own mistakes via instruction tuning through a simulated peer-review process between teacher LLMs. Demonstrated the effectiveness of our method across comprehensive experiments on mathematical(GSM8K, SVAMP), commonsense(StrategyQA), and logical(LogiQA) reasoning tasks.
[Sep 2023] ADRD Project
Worked in iRiS Lab with Professor Bo Xie from The University of Texas at Austin, explored automatic text classification techniques based on LLM for dementia and Alzheimer's patients based on their online posts.
[Jan 2023] LITE and Chief Complaint Project
Cooperated with Adam Frisch from UPMC and applied BART model to summarize the Electronic Health Records(EHRs). This method could help doctors identify the chief complaint of patients and give them diagnosis. We tried to use summarization model to extract critical information from long text and innovative ways to eliminate the hallucinations.
[May 2022] Ovarian Cancer Forum
Utilized the Ovarian Cancer Forum to help cancer patients via NLP techniques, which was developed by iRiS Lab and the School of Nursing at Pitt. We aimed to identify patients' disease trajectories based on their descriptions. Studied few-shot learning methods in the applications of text classification and recommendation systems.
[Jan 2020] Domestic Violence Crisis Recognition Method based on Deep Learning
Collected online posts about domestic violence and built deep learning models to identify domestic violence crisis automatically. Constructed CNN, RNN, LSTM, Bi-LSTM+self-Attention neural network models to accomplish text categorization task, and Bi-LSTM+self-Attention model had the best performance, with accuracy rate of 90.22% and recall rate of 93.98%.
[Jul 2019] Intelligent Chatbot Design
Remote research projects mentored by Fan Zhang from MIT. Interpreted intentions from user stock queries and supported daily dialogue occasions by spaCy. Integrated the bot on Wechat and enabled users to acquire expected stock information fast: demo.

I like working out and doing sports. I regularly go to gym every week, play soccer ball and basketball at weekends. And I am a trained ping-pong player.
Also, I play the drum or go out for a ride with my favorite Subaru WRX STI when feel stressed, which can make me feel relaxed! :)
