...different rankers are the same or not (I guess they?re different). In my understanding, the letor.cc basically just pass parameters ranker. It?s the ranker will do training and calculating things actually. So if we can generalize the form for training part, we don?t need functions like prepare_training_data_for_svm, prepare_training_data_for_listwise etc. We just need prepare_training_data instead. (We can benefit from inheritance of ranker in training part just like in ranking part) 2. There is one thing I have to confirm: once we have the training model (like model file of SVMRanker), we won...
