The document proposes a novel ranking method called Fidelity Rank (FRank) that combines the probabilistic ranking framework with the generalized additive model. It introduces a new fidelity loss function to address problems with existing loss functions like cross entropy. FRank was tested on TREC and web search datasets and significantly outperformed other learning to rank algorithms like RankBoost, RankNet and RankSVM in terms of metrics like MAP and NDCG. Future work could involve theoretical analysis of FRank's generalization bounds and combining it with other machine learning techniques.
