Heeey, welcome to Vu’s blog 👋

Hi, my name is Chan Kha Vu. I’m currently a Machine Learning engineer at Microsoft in Seattle, working on ranking models at a search engine called Bing. This blog is a place where I share my thoughts and study notes on machine learning, mathematics, and software engineering.

At the core of a Search Engine: Learning to Rank

Learning to Rank (LTR) is a core component of any recommendation system. It is the algorithm that forms the final list of items to be shown to the user. This blog post is a comprehensive introduction to the basics of LTR and Unbiased LTR.
