Anyone who has done some machine learning modelling in Oracle Analytics, might have been missing a bit more of quality metrics to better assess the quality of trained models. By default any generated classification model would enable users to evaluate trained models by reviewing Quality metrics such as Precision , Recall , Accuracy , F1 and False Positive Rate .
