ruby on rails - Changing an instance variable within dynamic method (dynamic resource using ActiveResource) -


i using dynamic dispatch define several class methods in class inherits activeresource. 

class invoice < activeresource::base   self.site = 'http://localhost:8080/'    def self.define(method)     define_singleton_method(method) |params = {}|       site = self.site       self.site = "#{self.site}/invoice/#{method.to_s.camelize(:lower)}"        puts "self.site -> #{self.site}"         results = invoice.all(params: params)        self.site = site       puts "changing self.site #{site}"             return results     end   end    define :get_details   define :put_approval   define :get_attachment   define :get_pending_notifications end

this works great first call, whatever (invoice.get_details, invoice.get_pending_notifications...), fails on second call.

i understand why happening , can fixed.

most site not getting reset properly. try this, works under ruby console:

class invoice < activeresource::base   self.site = 'http://localhost:8080/'    def self.define(method)     define_singleton_method(method) |params = {}|       site = self.site       begin         self.site = "#{self.site}/invoice/#{method.to_s.camelize(:lower)}"         invoice.all(params: params)       ensure         # code run, if there exception above         # , won't affect original value returned above         self.site = site       end     end   end    define :get_details   define :put_approval   define :get_attachment   define :get_pending_notifications end

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
