The technique often yields supreme predictive performance results. Orange embeds a popular implementation of SVM from the LIBSVM package. WebTree is a simple algorithm that splits the data into nodes by class purity (information gain for categorical and MSE for numeric target variable). It is a precursor to Random Forest. Tree in Orange is designed in-house and can handle both categorical and numeric datasets. It can also be used for both classification and regression tasks. smallest blu ray player hdmi
