![]() This code is taken pretty much line for line from weka.wikispaces. INSTALL WEKA PACKAGFES INSTALLFind Java Build Path -> Libraries either during project creation or afterwards under “Package Explorer” -> RClick project -> Properties.ģ) “Add External Jars…” and select the weka.jar from your download.Ĥ) Create a class file under the “src” folder. added convenience methods to the module: installpackages to install more than one package, installmissingpackage and installmissingpackages to install one or more packages if missing (can automatically stop the JVM and exit the process), uninstallpackages to remove more than one package in one operation 0.2. Have a look at the Packages article for more information on this topic. But, when I try to choose libsvm among classifiers, it is still grey and does not work.Quick, rough guide to getting started with Weka using Java and Eclipse.Ģ) Create a new project in Eclipse. IMPORTANT: make sure there are no old versions of Weka (3.7.2) in your CLASSPATH before starting Weka Installation of Packages A GUI package manager is available from the 'Tools' menu of the GUIChooser java -jar weka.jar. With Weka 3.7.2 and later, you can easily install packages through Weka's package manager interface, either official ones or unofficial ones. Throws: - if the package cant be installed for some reason. progress - optional varargs parameter, that, if supplied, is expected to contain one or more PrintStream objects to write progress to. ![]() After that, when use "java " command to test, I can see the property correctly shows the libsvm.jar in the right path. Parameters: packageName - the name of the package to install version - the version of the package to install (may be null if not applicable). This change is according to the trouble shooting part on. C:\Program Files (x86)\Java\jre7\lib\ext\QTJava.zip C:\Users\qsmile\wekafiles\packages\LibSVM\lib\libsvm.jar", but it does not work.Īnd I edited the "RunWeka.ini" file under the weka installed directory, and modified the last line into "cp=%CLASSPATH% C:\\Users\\qsmile\\wekafiles\\packages\\LibSVM\\lib\\libsvm.jar". Package RWeka contains the interface code, the Weka jar is in a separate package RWekajars. So I add "C:\Users\qsmile\wekafiles\packages\LibSVM\lib\libsvm.jar" to the CLASSPATH environment variables, which is now ". Weka is a collection of machine learning algorithms for data mining tasks written in Java, containing tools for data pre-processing, classification, regression, clustering, association rules, and visualization. I checked the folder of the downloaded packages, and I can see the libsvm.jar in "C:\Users\qsmile\wekafiles\packages\LibSVM\lib". ![]() EBMC searches over the subspace of Bayesian networks that best predict the target node. Your screen shot shows the Explorer window, but to install a package, you should go back to the GUI Chooser and select the Package Manager under the Tools menu. EBMC builds a tree-augmented nave Bayes model (TAN). I installed weka 3.7.10 (with jre1.7 included), and installed libsvm via its package manager.īut when I use Explorer to open the data and try to choose a classifier, I found the "libSVM" under "classifiers -> functions" is grey and not usable (It chooseable actually, but when I choose it, the start button is disabled) A java WEKA extension for the Efficient Bayesian Multivariate Classifier (EBMC) algorithm.
