Hi Hanxiao Sun,
First of all welcome aboard and congratulations. Yes, your project, as we
agreed during the discussion, will focus on algorithms of learning to rank.
Main idea is to check the existing algorithms and add a few more. Mostly
you will be working on the ranker.cc part and its subclasses. You will need
to add the neural network part for the listmle and listnet (probably
ranknet as well).
We also have another student (Jiarong Wei) for Letor project who will
mainly take care of the API, test cases, feature selection algorithms and
general framework. We should get resolved the common part you are going to
touch. The evaluation part fits more naturally to your module.
It would be fantastic during this community bonding period if we can decide
upon the intersection of both projects. Also on your part, you should get
familiarise yourself with the theory behind the algorithms you are going to
implement (There are a couple of very nice tutorial on learning to rank)
also the algorithm paper is the best source. You can also have a look at
the reference implementation (if available) for the algorithms. It would
also be very nice if you keep in mind the efficiency part (try to
parallelize).
Finally, you should also create and actively maintain your project page as
previous years http://trac.xapian.org/wiki/GSoC2011 and
http://trac.xapian.org/wiki/GSoC2012 with ideas, theory and as much details
as you want/can!
This year we will mentor as a group so although you might have a assigned
mentor but you should ask your questions on IRC and/mailing list and one of
us (who is readily available and can help) would help you out!
Cheers,
Parth.
Cheers,
Parth.
