About zeng
I'm currently an Applied Data Scientist at Microsoft working on the enterprise search stack in M365. I have been involved in various projects related to semantic search, where I worked on training and deploying ranker models to all enterprise customers worldwide, finetuned on embedding models for an improved enterprise search experience, and the building and deployment of vector index of files in enterprise M365. Prior to the start of my professional career, I was also heavily involved in the creation of a signal processing module (using Wavelets transformations) in Julia programming language, and is now being served as an official Julia package that is used by many enthusiasts in this field of study.
