similar to: Example on how to boost a field?

I have been trying to model a labeled graph using ActiveRecord (trunk version). Basically, I have a ''Node'' model which represents a node linking to other nodes. Links (aka edges) are labeled (i.e., have a ''label'' attribute and other behavior). Thus I decided to model edges as an ''Edge'' model and use a ''has_many :trough''

How can I get a list of all model classes in the domain of a Rails application (all models, both in "app/models" and in components/somedir/model.rb)? Thanx in advance for your precious help! Edoardo "Dado" Marcora

How can I avoid AR confusing way of handling default values for attributes w/ :null => false? This issue came up before, but I could not find an answer that resolves the issue, which I outline below: First, I add a test table using migrations: class AddTestTable < ActiveRecord::Migration def self.up create_table "users", :force => true do |t| t.column

I was wondering about the potential impact of setting the boost field for an index after the index has been created and optimized. I know that some field_info settings can''t really be modified, such as :store or :tokenize, as they really apply when you are indexing, but is boost? If boost is only used for searching, can it be modified dynamically when searching? Thanks for any

I was wondering if there was a good way to either balance the relevancy score with recentness of matching documents- or include the recentness in the score somehow? Thanks, Ben -- Posted via http://www.ruby-forum.com/.

I''m making a simple business directory search and I want to boost the relevance of the ''name'' field over the ''address'' field - both stored in the same document in the same index. Here is some console code to demonstrate what I am actually doing >> include Ferret::Document => Object >> doc = Document.new => Document { } >> doc

Hi, I''m confused about managing field boosting ... I have set the :boost for the :name field in my docs to 10, via :boost => 10 Then I performed a search for ''keith'' over all fields via with *:(keith*), expecting a doc with Keith in the :name field to come out on top. But another doc with Keith mentioned in other fields (:comments, :address) scored higher. I

Hi I am using boosting for a classification and prediction problem. For some reason it is giving me an outcome that doesn't fall between 0 and 1 for the predictions. I have tried type="response" but it made no difference. Can anyone see what I am doing wrong? Screen output shown below: > boost.model <- gbm(as.factor(train$simNuance) ~ ., # formula +

I've been doing some experiments with the Boost Graph Library (BGL) and interfacing to llvm's GraphWriter system. I'm using GBL for some custom work and needed a way to hook BGL's write_graphviz into GraphWriter to use the existing display infrastructure. To do this I added a HAVE_BOOST configure item and #ifdef'd the Boost support code in GraphWriter. Is this useful to

The BGL (Boost Graph Library) defines tie(), which is exactly what the tie() defined in STLExtras.h. The header files of GBL use boost::tie(), and other boost libraries use boost::tie() too.

Hi, I am not sure how widespread this problem is, but definitely occurs for me on 64 bit Win 7 with a 64 bit R. I think I have isolated the issue (to a certain extent) in the attached Test.cpp file. Basically, I think linking with boost serialization is causing the plugin to fail. If I compile Test.cpp with line 43 (Dummy* Read() ...) commented out, I get the expected output in R: >

Hi, Recently, I made an R package that used the C++ library Boost.Thread (http://www.boost.org/doc/libs/1_54_0/doc/html/thread.html) for multithreading. Previously, I have posted a question at stackoverflow (http://stackoverflow.com/questions/19651954/is-it-possible-to-build-an-r-package-which-use-rcpp-and-boost-thread-on-http), and I also asked at rcpp-devel

Hi, not sure if this is the right place, but I am experiencing a problem using clang++ (3.9.1) with Boost Filesystem. I have this simple program: ------------------------------------------------------------------------ #include <iostream> #include <boost/filesystem.hpp> using namespace boost::filesystem; int main(int argc, char* argv[]) { if (argc < 2) { std::cout

The header files in boost do not use fully-qualified tie(). I probably should not modify them. But my .cpp file #include them. I hope I could "using namespace" boost

I tried building boost 1.45 release with clang 2.9 following instructions on http://blog.llvm.org/2010/05/clang-builds-boost.html but got the following result: $ clang++ --version clang version 2.9 (trunk 123420) Target: x86_64-apple-darwin10 Thread model: posix $ ./bjam toolset=clang Building the Boost C++ Libraries.

Hi, I have got a peculiar requirement in my project. I need to apply some boost to different fields of my index. But the problem is the boost that needs to be applied is dynamic. It changes for everyrow of data.I am storing that in the index itself while building it. Is there anyway by which i can add the boost to search query while searching. at present am retreiving the whole set of searched
