Hi Maybe I can start off with Hanxiao's branch but I can see there are two repos. https://github.com/v-hasu/xapian/tree/gsoc2014-evaluation https://github.com/v-hasu/xapian/tree/gsoc2014 which one should I pick? I have already successfully built xapian from the git repository ( https://github.com/xapian/xapian) Since I am new to ML (well I dont know anything about it?), should I read the paper try to...

...broken functions and is custom made for training with INEX 2010 dataset. The intention is to make it usable for a user provided database. Currently I am using xapian-docsprint/data/100-objects-v1.csv as my database and some manually written queries and qrels to make things work. 2. Going through v-hasu's GSoC 2014 code to understand extra functionalities added by him and planning how to introduce code from his branch. In summary, the approach I will follow is going to be: 1. Creating a code example that lets the user use 100-objects-v1.csv as the database and use Letor features and API to m...

Hello everyone, I have completed introducing some code from v-hasu's branch into mine, mainly for Features, FeatureVector and FeatureManager classes. I have pushed the changes to https://github.com/ayshtmr/xapian/tree/letor-update. I am now proceeding to write unit tests for feature modules. There are a few things that I wanted to clarify: 1. I have introduc...

...for the first and second week of coding which have already been done (except writing tests). So, I'd like to adjust the timeline according to it. 2. Ensuring that features (mainly FeatureManager, FeatureVector and Features classes) are stable and no code is left that is to be introduced from v-hasu's branch into mine. Once done, proceed to write tests for this portion. 3. Discussion about which dataset to use. Regards, Ayush -------------- next part -------------- An HTML attachment was scrubbed...

Hi I am on Debian verson 7.7, GCC 4.7.2 and make 3.8.1. I cloned the code : git clone https://github.com/v-hasu/xapian git checkout gsoc2014-evaluation rm xapian-letor/nobootstrap ./bootstrap ./configure --no-documentation make CXXFLAGS='-w' and I get a different set of errors --- ranker.cc: In member function 'std::string Xapian::Ranker::get_cwd()': ranker.cc:80:36: error: 'getcwd'...

I'd suggest that a good thing to look at would be functional tests of the metrics and algorithms in Hanxiao Sun's work from this summer. You'll generally need to go either to the original paper, or find an alternative implementation, to build up a series of tests that demonstrate that the implementation is doing what it is supposed to. Xapian-core contains a test framework which it

...s, three evaluation metrics and two blending algorithms in letor. I have post the evaluation result of new algorithms on my GSoC wiki page ( http://trac.xapian.org/wiki/GSoC2014/Learning%20to%20Rank%20Hanxiao%20Sun/Report). And the latest code was on gsoc2014-evaluation branch( https://github.com/v-hasu/xapian/tree/gsoc2014-evaluation). I am trying to make some PRs now. There are several things can be done in letor furture, in my opinion. I have wrote down them on my report page( http://trac.xapian.org/wiki/GSoC2014/Learning%20to%20Rank%20Hanxiao%20Sun/Report#FurtureWork ). I will remain in the c...

Hello, I applied to letor stabilisation project for gsoc. I'd like to use coming weeks to improve the workability of xapian-letor. For that, I'm planning to refactor code in current master and begin writing some tests for it. Before adding tests, I think it would be better if xapian-letor could be made consistent with how xapian-core is written. For that, I'd first like to

I use Ubuntu12.04, GNU Make 3.81 and I am not sure if I use some special configure options. The commands I use after clone the repo are as follows: cd xapian ./bootstarp ./configure make cd xapian-letor aclocal -I ../xapian-core/m4 libtoolize --force autoconf autoheader automake --add-missing ./configure make Is this normal? 2014-12-07 22:37 GMT+08:00 James Aylett <james-xapian at
