HKUST(GZ)

I am a PhD student at the Hong Kong University of Science and Technology (Guangzhou), starting from Fall 2024. I am honored to be supervised by Professor Yuyu Luo. Previously, I obtained my bachelor’s degree from the School of Information, Renmin University of China. My research interest primarily focuses on LLM Based Agents, with a particular emphasis on reasoning ablity and the paradigm of constructing agents that are adaptable to multiple environments.

I am building a community called MindForge, aimed at bringing together researchers and engineers interested in intelligence to explore autonomous and efficient agents across different environments. If you are interested, feel free to reach out to me.

You can find my CV here: didi’s Curriculum Vitae.

AFlow: Automating Agentic Workflow Generation

Jiayi Zhang, Jinyu Xiang, Zhaoyang Yu, Fengwei Teng, Xionghui Chen, Jiaqi Chen, Mingchen Zhuge, Xin Cheng, Sirui Hong, Jinlin Wang, Bingnan Zheng, Bang Liu, Yuyu Luo, Chenglin Wu

We introduces AFlow, an automated framework that reformulates workflow optimization as a search problem over code-represented workflows, using Monte Carlo Tree Search to efficiently explore and refine workflows through code modification and execution feedback. By leveraging this approach, AFlow achieves superior performance compared to state-of-the-art baselines across multiple benchmarks, while also enabling smaller models to outperform larger ones at a fraction of the cost.

DATA INTERPRETER: AN LLM AGENT FOR DATA SCIENCE

MetaGPT Community

We introduces the Data Interpreter, an advanced LLM-based agent designed to enhance problem-solving in data science. It employs three key techniques: dynamic planning with hierarchical graphs, dynamic tool integration, and logical inconsistency identification. The Data Interpreter outperforms existing open-source solutions in various data science and real-world tasks, showing significant improvements in machine learning, mathematical problem-solving, and open-ended tasks.
