Secara singkat dan jelas seperti berikut. pembahasan lebih lanjut kalian bisa cari beberapa materi yang sudah banyak di share di google. kali ini Saya akan membahas inti dari menggunakan Metode Klasifikasi populer yaitu Decision Tree. A perfect model would have a log loss of 0. Log loss increases as the predicted probability diverges from the actual label. So predicting a probability of .012 when the actual observation label is 1 would be bad and result in a high log loss. There is a more detailed explanation of the justifications and math behind log loss here.

Università di Pisa 2 Classification Attribute to be predicted (By default, the class is taken to be the last attribute in the data). Options for testing the results of the chosen Higher the beta value, higher is favor given to recall over precision. If beta is 0 then f-score considers only precision, while when it is infinity then it considers only the recall. When beta is 1, that is F1 score, equal weights are given to both precision and recall. In fact, F1 score is the harmonic mean of precision and recall.
