Hi all, I want to use ROC curve (AUC - Area Under the Curve) for evaluation of recommended system in case of retailer. Could you please give an example of True Negative value?
i.e. True Positive is the number of items on the Recommended List that are appeared on the test data set, where the test data set may be the 20% of the full data. Thank you. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
