RankLib
Overview
RankLib is a library of learning to rank algorithms. Currently eight popular algorithms have been implemented:
- MART (Multiple Additive Regression Trees, a.k.a. Gradient boosted regression tree) [6]
- RankNet [1]
- RankBoost [2]
- AdaRank [3]
- Coordinate Ascent [4]
- LambdaMART [5]
- ListNet [7]
- Random Forests [8]
It also implements many retrieval metrics as well as provides many ways to carry out evaluation.
