[Xapian-devel] Regarding Letor

[Mayank Chaudhary]

Hi Parth,

A few things I wanted to confirm-

1. Is fcount meant to store the number of features in the featurevector.h?
What is the need to keep it inside the feature vector. Will it not be same
for all the feature vectors. And by default that must be 19.

2. In svmranker.cc there is a data member called weights[]. Is it possible
to get the weights from the learned model in libsvm. Actually I can't find
any in letor_internal_refactored.cc. And shouldn't there be a data member
as struct  *svm_model** which will point to the model learnt so that
functions *load_model* and *save_model* don't need an extra argument.

Thanks

Mayank
