Listwise approach
WebThe main problem with this group of approaches is that the connection between the listwise loss function and the targeted IR evaluation metric is unclear, and therefore … WebThe listwise approach addresses the ranking problem in the following way. In learning, it takes ranked lists of objects (e.g., ranked lists of documents in IR) as instances and …
