On the evening of October 21, the School of Computer Science successfully hosted the 10th session of the @World "Touch the Academic Frontier" International Exchange Activity at the Corner Conference Room on the second floor. The presenter of this event was student Sun Qingshuang.
In her presentation, Sun Qingshuang introduced her research achievement "A Dynamic Message Size Scheduling Method for Multi-Agent Communication Under Bandwidth Constraints", which was accomplished during her study at Vrije Universiteit Brussel. In multi-agent systems, each agent needs to make decisions in its local environment and share information with other agents when necessary. However, communication bandwidth is often limited in practical applications, which poses challenges to information exchange in multi-agent systems. Given the limitations of traditional methods under constrained bandwidth, her research proposed a novel dynamic message size scheduling algorithm—DSMS (Dynamic Size Message Scheduling). Its core innovation lies in the introduction of Fourier transform technology: it compresses messages through frequency-domain analysis and retains low-frequency information to maintain the integrity of key data. Meanwhile, Fourier transform features a global perspective and differentiability, which facilitates its integration with deep reinforcement learning methods.
Funded by the China Scholarship Council Program for Postgraduates Studying Abroad at High-Level Universities, Sun Qingshuang studied at the Artificial Intelligence Laboratory of Vrije Universiteit Brussel (Flemish) for 26 months, from November 2021 to January 2024. During her study, she proposed an adaptive dynamic message compression algorithm for multi-agent collaboration in bandwidth-constrained environments, which effectively addressed the impact of bandwidth limitations on communication and collaboration efficiency in multi-agent systems. This research achievement has been published in IEEE Transactions on Mobile Computing, a CCF Class A journal in the computer science field.
As one of the initiatives to enhance students’ international perspective and professional competence, the @World "Touch the Academic Frontier" series of international exchange activities aims to enable every participant to gain valuable experience, keep abreast of cutting-edge developments in computer science, stimulate academic inspiration and innovative thinking through interactions with outstanding peers, promote knowledge exchange, and facilitate personal growth.
