I’m a Natural Language Processing researcher at Hainan University.

I obtained my Ph.D. degree at Zhejiang University & Westlake University in 2024.

I was advised by Prof. Yue Zhang at WestlakeNLP Lab. As one of the first members of WestlakeNLP Lab, I designed the badge of the lab, cooperated with Prof Yue Zhang for the NLP MOOC.

After graduation, I joined Huawei as a senior engineer at the department of ICT.

My research interests are large language model reasoning, especially logical reasoning.

I have a BILIBILI channel. I’m planning to share more contents on LLM tutorials and AI podcasts.

Shoutout to my big bro — I couldn’t have started my PhD journey without him.

Generative Pre-trained Transformer 4 (GPT-4) demonstrates impressive chain-of-thought reasoning ability. Recent work on self-instruction tuning, such as Alpaca, has focused on enhancing the general proficiency of models. These instructions enable the model to achieve performance comparable to GPT-3.5 on general tasks like open-domain text generation and paraphrasing. However, they fall short of helping the model handle complex reasoning tasks. To bridge the gap, this paper presents LogiCoT, a new instruction-tuning dataset for Logical Chain-of-Thought reasoning with GPT-4. We elaborate on the process of harvesting instructions for prompting GPT-4 to generate chain-of-thought rationales. LogiCoT serves as an instruction set for teaching models of logical reasoning and elicits general reasoning skills.
