xgboost和 lightgbm 都可以安装Python包的吧，我是直接跑命令行，这两个工具都还挺好用的~LightGBM Rank...
利用lightgbm做learning to rank 排序,主要包括: 一.data format (raw data -> (feats.txt, group.txt)) python lgb_ltr.py -process 1.raw_train.txt 2.feats.txt: 3.group.txt: 二.model train (feats.txt, group.txt) -> train -> model.mod ...
优化基于评价指标的 ranking error 的连续可微的近似,这种方法就可以直接应用已有的优化方法,如SoftRank,ApproximateRank,SmoothRank 优化基于评价指标的 ranking error 的连续可微的上界,如 SVM-MAP,SVM-NDCG,PermuRank 使用可以优化非平滑目标函数的优化技术,如 AdaRank,RankGP 上述方法的优化目标都是直接和 ranking ...
1. To run DLA in ./DLA/ and the python scripts in ./scripts/, python 2.7+ and Tensorflow v1.4+ are needed. Data Preparation for the Initial Ranker For simplicity, here we show the instruction of data preparation for SVMrank (the intial ranker) on Yahoo letor (the simulation experiment...
