Introduction

Learning to rank (LTR) is a class of supervised machine learning algorithms aiming to sort a list of items in terms of their relevance to a query. In classical machine learning in problems like classification and regression, the goal is to predict a single value based on a feature vector. LTR algorithms operate on a set of feature vectors and predict the optimal order of items.

LTR has many different …
