hi new machine learning , spark mllib. have created randomforest classifier model using randomforest.trainclassifier() training data set categorical in nature , have response/target variables actionable/noactionable. have created predictionandlables rdd using test data , model.predict() trying following validate model accuracy. multiclassmetrics metrics = new multiclassmetrics(predictionandlables.rdd()) system.out.println(metrics.precision()); //prints 0.94334140435 system.out.println(metrics.confusionmatrix()); //prints following 1948.0 0.0 117.0 0.0 now if see model accuracy printed using precision() method seems around 94% if see above confusion matrix seems wrong have 1948 nonactionable target variables , 117 actionable target variable in test data set. according confusion matrix predict nonactionable correctly , not predict @ actionable variables. please me understanding confusion matrix , why precision 94% . results contradicting. please guide in advance...

class numberstorage { public: static numberstorage& instance(); double getnumber(); void setnumber(double d); private: numberstorage() { number = 0.0; }; double number; }; colorramps& colorramps::instance() { static colorramps instance; return instance; } i think have read somewhere instance() method implemented way thread safe. correct? guess must lock member variable number in getnumber() , setnumber()? how do (c++11)? c++11 compiler makes thread safe. static variables can created 1 single thread. other questions locks both depend on how threads should work methods. if have multiple threads can 1 same piece of memory - use locks. simple lock can used std::unique_lock , std::mutex : void setnumber(double number) { static std::mutex _setnumberlock; std::unique_lock _lock(&_setnumberlock); // code }
