Hi, I'm new to R. I'm trying to do some extreme value theory analysis, looking at the Mean Excess Plot of a series. These are the commands I type to get the plot: x=read.table("data.txt",header=T) goa=(x[,3]) meplot(goa) I can see the plot, but I would like to see the values of the x and y axis. According to this page

Hi, Wanted to know if other normalization techniques like normalization by standard-deviation have been tried to normalize the Feature-list in Letor. Regards, Ayush Pandey.

Hi all, While building from git with xapian-letor not ignored in bootstrap, I am getting the following make error: In function `main': /home/ayush/Desktop/xapian/xapian-letor/bin/xapian-letor-update.cc:98: undefined reference to `Xapian::Internal::str(unsigned int)' /home/ayush/Desktop/xapian/xapian-letor/bin/xapian-letor-update.cc:99: undefined reference to

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 all, I am trying to call the R script/ R Program via my Shell Script. I need to pass a file to the R script as an argument. When I am trying to do that I am getting error and only first line of the file is being read. Can you tell me how should I do that so that it reads the entire file in a R object so that later I am able to process the matrix operation on that file. It is a tab delimited

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;

Hi, I'm Ayush an undergraduate Computer Science student from Thapar university, India. I was fiddling with xapian since the morning and trying to understand the code and internals of Xapian. I tried implementing the bite sized project idea posted here: https://trac.xapian.org/wiki/ProjectIdeas#AddnewOmegaScriptcommandtodoasubstringsearch but could not understand what needs to be returned when

Hello, I'm Ayush from New Delhi, India. I am interested in Letor Stabilisation project for GSoC. I have a good background in machine learning. Sorry for getting in so late, university exams were holding me back. I'll try to cover as much as I can in the coming week. I am following the plan of attack suggested on the project page. Following are the things that I have completed: 1.

Hello everyone! I'm Ayush Tomar, junior undergrad in Computer Science from New Delhi, India. I love C++ coding and working on machine learning and information retrieval project. I was exploring the GSoC ideas for Xapian and the project on "Adding Weighting Schemes" looked really interesting to me. I wanted to work on text mining/IR this summer and this idea seems perfect! I have

Hi, I would like to know if there is some debugger in R where I can check that I am not using or not doing calculation on my previously stored objects. I can't use rm (list = ls()) to remove all the objects since I am using a for loop for reading 500 files and making making common calculation for each file, therefore I need to keep the track of my iterator. Is it possible to remove everything

Hello James, I am working on breaking down Features into sub-classes. Should each of the features get their own sub-class, or should the grouping be done according to type? i.e. query-document pair dependent, query-dependent and document dependent sub-classes. Using this approach makes more sense if we plan to add support for user to include query-dependent and document-dependent features in

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

I am calculating some values that I am inserting into a data frame. From what I have read, creating the dataframe ahead of time is more efficient, since rbind (so far the only solution I have found to appending to a data frame) is not very fast. What I am doing is the following: # create data frame goframe = data.frame(goA = character(10), goB = character(10), value = numeric(10)) goframe[1,] =

Hi All, The Linux version of the machine on which I want to install OCFS is: $uname -r 2.4.9-e.25kmap1enterprise Can any body suggest me which version and the module of OCFS should I install. The machine on which I want to install has 2-CPUs. Thanks, Ayush

Hello, I wanted to decide the dataset that should be used for Letor stabilisation project. I think 2009 INEX Wikipedia Collection <http://www.mpi-inf.mpg.de/departments/databases-and-information-systems/software/inex/> should work fine. It's a collection of 2,666,190 XML articles, 115 topics <http://inex.mmci.uni-saarland.de/protected/adhoc/2009-topics.zip>, 50,275 qrel

Hello devs! Could you please expand on the project idea of integration of xapian in a framework with an example. I did not fully understand the requirements of this project. Also I want to discuss an idea of my own. Xapian doesn't have an auto complete feature. It is quite common for an search engine to have an auto complete feature. What I propose is a API that is totally separate from
