...vector<Features*> FeatureList, which initialises each Feature sub-class object mentioned in the FeatureList (supplied at the time of training/ranking or as deafult set). At present, letor is mostly centred around RankList (for both training and ranking), whereas RankList is just a vector of FeatureVectors corresponding to a qid. Having RankList in ranking has no meaning since qid isn't required once the training part is over. (letor_rank(*) method in letor_internal.cc supplies a junk qid to the RankList while performing the ranking, which points out that the RankList approach isn't quite cor...

Hello James, Parth, Following our discussion on IRC and on code review, the way FeatureVector class works needs some discussion. Presently, the FeatureVector class is defined as follows, with a fixed number of feature count (19): class FeatureVector::Internal : public Xapian::Internal::intrusive_base{ friend class FeatureVector; double label; double score;

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 introduced a lot of code in a single

Hello everyone, My name is Ayush Tomar. I'll be working on Learning to Rank stabilisation project over the summers. Here are a few things that I plan to do in coming few days: 1. Revise the timeline. There are some portions that I had kept 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.

Hi Rishabh, I think its better not to expose RankiList to Letor.h and make it better user friendly. So my suggestion is to convert RankList to the following statement in this method. std::map<Xapian::docid, double> letor_score(const Xapian::MSet & mset); So just convert the RankList in std::map<Xapian::docid, double> format in the methods where you need to return. Parth. On

Hi all, Thank you for giving me the opportunity to work with Xapian :) I am Jiarong Wei, a third year undergraduate student in Zhejiang University, China. In GSoC 2014, I will work on Letor module with Hanxiao Sun. Here are some questions I encountered these days, 1. In letor.cc, we have two parts of functions: the training part and the ranking part. I?ll use SVMRanker as an example. The

Hi all, I am having an issue related to installing packages on windows with R-3.6.0. When installing a package that is in use, I expected R to stop with an error. However I am getting a warning that the DLL copy was not successful, but the overall package installation IS successful. This is quite dangerous because the old DLL and the new R code could be incompatible. I am definitely not the

thanks for the tip Jan. However it would be nice if I didn't have to handle this myself for all of my packages. (and teach my students how to do that) BTW I tried to disable staged installation, and the issue still happens: th798 at cmp2986 MINGW64 ~/projects/max-generalized-auc (master) $ R_INSTALL_STAGED=FALSE R --vanilla -e

Also note that this can lead to people not being able to load the package if the set of .Call entry points has changed between the old and new versions of the package. We strongly suspect that this is what happened to this Bioconductor user: https://support.bioconductor.org/p/121228/ Note that she's installing the binary and in this case no warning is issued. All we see is: package

thanks for your input Herv?. Glad to hear I'm not the only one still having this issue. In my opinion install.packages should stop with an error (instead of a warning) if this happens. However even if you want to keep the warning, at least make it so that users can set options(warn=2) to get an error if they want one. I tried setting options(warn=2) but for some reason I still get a warning.

Hi Toby, AFAIK it has not been addressed in R. You can handle the problem on your package side, see https://github.com/Rdatatable/data.table/pull/3237 Regards, Jan On Thu, May 30, 2019 at 4:46 AM Toby Hocking <tdhock5 at gmail.com> wrote: > > Hi all, > > I am having an issue related to installing packages on windows with > R-3.6.0.
