Learning to Rank: pointwise 、 pairwise 、 listwise - 知乎
WebOct 1, 2024 · Pairwise learning naturally arises from machine learning tasks such as AUC maximization, ranking, and metric learning. In this paper we propose a new pairwise learning algorithm based on the additive noise regression model, which adopts the pairwise Huber loss and applies effectively even to the situation where the noise only satisfies a weak ... sky blue football teams

WebSep 9, 2024 · The goal is to minimize the average number of inversions in ranking.In the pairwise approach, the loss function is defined on the basis of pairs of objects whose … WebHingeEmbeddingLoss. Measures the loss given an input tensor x x and a labels tensor y y (containing 1 or -1). This is usually used for measuring whether two inputs are similar or dissimilar, e.g. using the L1 pairwise distance as x x, and is typically used for learning nonlinear embeddings or semi-supervised learning.
