c++ - How do I save the state of std::mersenne_twister_engine to restore it later? -


i save state of std::mersenne_twister_engine can restore @ later time. know can save original seed , call discard roll engine forward number of steps, requires knowledge of number of times engine advanced, not mention discard seems inefficient (o(n)) way roll engine forward.

how go saving off exact state of engine?

according this, engine should support serialization , standard stream.

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 ...
