1. The data mining problem of this study is most related to the classification super-problem, as a supervised machine-learning algorithm is used. 2. The source of the data is from DONKI, which is dependency orientated data compiled from several instruments. 3. They used extracted features. 4. They used all the features except the flare class feature. 5. Yes 6. The cleaning process attempted to remove noise in the HMI vector magnetic field data. 7. It addressed the problem by rejecting any data which is not within 70 degrees of central meridian. 8. Yes 9. 10. 11. The name of the algorithm used is SVM. 12. The algorithm is applied onto extracted features selected by the univariate feature selection algorithm. 13. 14.
