Hongbo Ma - 马洪博

I'm a final year undergraudate student from Xinya College and Department of Computer Science and Technology, Tsinghua University. In addition, I am also minoring in Economics and Finance at School of Economics and Management, Tsinghua University.

My research interests are focused on computer vision, computer graphics and generative models. I also hope to expand my research boundaries, for example, into the intersection of AI and other disciplines.

Paper / Twitter post

We propose Tool-Use-Mixture (TUMIX), leveraging diverse tool-use strategies to improve reasoning. This work shows how to get better reasoning from LLMs by running a bunch of diverse agents (text-only, code, search, etc.) in parallel and letting them share notes across a few rounds. Instead of brute-forcing more samples, it mixes strategies, stops when confident, and ends up both more accurate and cheaper.
