你必需在使用一个Weka函数(ex: weka.classifiers.Classifier.buildClassifier(data))之前设置Class Index。 3.5.5和更新的版本 DataSource类不仅限于读取ARFF文件,它同样可以读取CSV文件和其它格式的文件(基本上Weka可以通过它的转换器(converters)导入所有的文件格式)。 import weka.core.converters.ConverterUtils.DataSou...
Its last release was in 2004, and it shows. Weka is actually a suite of learning algorithms, which include Decision Tree algorithms. Its API is marginally better than jaDTi, but still quite ugly by today's standards. Worse, it seems to be a memory hog, and had various other minor ...
. The entire system was built using the open source applications ImageJ, Weka and their public Java classes and was linked by a specially developed code. No expensive commercial software was used. Eight machine learning classification algorithms, Naive Bayes classifiers (NBC), k-nearest neighbours ...
