jni - How to compile JNI_CreateJavaVM -


i have following code. command in linux compile piece of code. gcc thisfile.c says jni_version_1_6 undeclared..

#include <stdio.h> #include <jni.h> #include <string.h>  jnienv* create_vm(javavm ** jvm) {      jnienv *env;     javavminitargs vm_args;     javavmoption options;      vm_args.version = jni_version_1_6; //jdk version. indicates version 1.6     vm_args.noptions = 1;     vm_args.options = &options;     vm_args.ignoreunrecognized = 0;      int ret = jni_createjavavm(jvm, (void**)&env, &vm_args);     if(ret < 0)         printf("\nunable launch jvm\n");     return env; }   int main(int argc, char* argv[]) {     jnienv *env;     javavm * jvm;      return 1; }

ok, got myself answered. hope someone

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 ...
