Tīmeklis4 LambdaRank One approach to working with a nonsmooth target cost function would be to search for an optimiza-tion function which is a good approximation to the target cost, but which is also smooth. However, the sort required by information retrieval cost functions makes this problematic. Even if the target Tīmeklis前言. Ranknet是实践中做Top N推荐（或者IR）的利器，应该说只要你能比较，我就能训练。. 虽然名字里带有Net，但是理论上任何可微模型都行（频率派大喜）。. Ranknet的下一步是Lambda Rank，引入了 \Delta NDCG ，训练更加有针对性，但是论文原文说，Ranknet已经很强了 ...
