LibsvmModel test

---

test(self, frame, label_column, observation_columns=None)

[ALPHA] Predict test frame labels and return metrics.

Parameters:

frame : Frame

A frame whose labels are to be predicted.

label_column : unicode

Column containing the actual label for each observation.

observation_columns : list (default=None)

Column(s) containing the observations whose labels are to be predicted and tested. Default is to test over the columns the LIBSVM model was trained on.

Returns:

: dict

A dictionary with binary classification metrics. The data returned is composed of the following keys:

‘accuracy’ : double

The proportion of predictions that are correctly identified

‘confusion_matrix’ : dictionary

A table used to describe the performance of a classification model

‘f_measure’ : double

The harmonic mean of precision and recall

‘precision’ : double

The proportion of predicted positive instances that are correctly identified

‘recall’ : double

The proportion of positive instances that are correctly identified.

Predict the labels for a test frame and run classification metrics on predicted and target labels.
