WebIn learning to rank, one is interested in optimising the global or-dering of a list of items according to their utility for users. Popular approaches learn a scoring function that scores items individually (i.e. without the context of other items in the list) by optimising a pointwise, pairwise or listwise loss. The list is then sorted in WebLTR（Learning to rank）是一种监督学习（SupervisedLearning）的排序方法，已经被广泛应用到推荐与搜索等领域。传统的排序方法通过构造相关度函数，按照相关度进行排序。 … s21 ultra best buy
