XinyuMa (马新宇)

I am now a senior software engineer / researcher at Baidu Search. My work at Baidu includes research and development on ranking models powering Baidu’s core search engine and now focusing on developing the next-generation search product based on large language models.

Prior to joining Baidu, I earned my Ph.D. degree in Computer Science from the Institute of Computing Technology, Chinese Academy of Sciences, under the supervision of Prof. Jiafeng Guo in 2023. Additionally, I received the B.E. degree from Shandong university in 2017.

I have broad research interests in information retrieval and natural language processing, with a particular emphasis on harnessing the capabilities of large language models to revolutionize the way we access, understand, and utilize information.

Highlight

• A benchmark for evaluating instructed information retrieval models: MAIR
• A survey of Pre-training for IR: Pre-training Methods in Information Retrieval
• A curated list of awesome papers on pre-trained models for IR
