Relevance Debugging and Explaining at LinkedIn

Daniel Qiu and Yucheng Qian, LinkedIn


At LinkedIn, we provide value to our members by serving information most relevant to them. Because of the complexity of the distributed system, it's hard for our AI engineers to understand how does the machine learning model make the prediction to provide the value to our members in the online system.

In this talk, we will cover how we provide the infrastructure to instrument our online relevance serving system to help AI engineers better understand their machine learning models and debug issues, and introduce two debugging tools that we provide for search and feed to visualize the relevance information.
