This table shows some of the predictions of our best representation of data, a Random Forest classifier for the task of exoplanet detection (Confirmed), and a SVM RBF for the task of non-exoplanet detection (False Positive). It should be mentioned that the Confirmed column on that system counts the number of confirmed exoplanets at the date of the study (September 2017), as long as Star is the name of the Parent star in the system; The ones with no information doesn’t show this value.
