Ranking

Objective

You want to build a model that will display the most relevant results for a searcher’s query. Extra emphasis should be applied to the relevance of the top few results since a user generally focuses on them more on the SERP.

📝 Learning to Rank (LTR): A class of techniques that applies supervised machine learning (ML) to solve ranking problems. The pointwise and pairwise techniques that we will apply fall under this class.
