...d how about the cross validation for the training set? Is there any method included in the current project? For SVM method, I found letor_learn_model() has been commented out, but I didn't find any other file contain this function (or maybe in letor_internal.cc)? Finally I found a file called letor_internal_refactored.cc file, is that the latest version of letor_internal.cc ? Is letor_internal.cc still being used? Thank you very much. I am waiting for your reply. -- Jia Xu -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.xapian.org/pipermail/xapian-devel/attachm...

1.Could you explain why are these libraries included in all the xapian-letor headers? #include<xapian/intrusive_ptr.h> #include<xapian/types.h> #include<xapian/visibility.h> Or just provide me with the documentation of these header. I looked into these header files but couldn't anything substantial. 2.
