Models LibsvmModel


class LibsvmModel

Create a ‘new’ instance of a Support Vector Machine model.

Support Vector Machine [R9] is a supervised algorithm used to perform binary classification. A support vector machine constructs a high dimensional hyperplane which is said to achieve a good separation when a hyperplane has the largest distance to the nearest training-data point of any class. This model runs the LIBSVM [R10] [R11] implementation of SVM. The LIBSVM model is initialized, trained on columns of a frame, used to predict the labels of observations in a frame and used to test the predicted labels against the true labels. During testing, labels of the observations are predicted and tested against the true labels using built-in binary Classification Metrics.
