The Area Under the Receiver Operating Characteristics (ROC) Curve, referred to as AUC, is a well-known performance measure in supervised learning domain. Due its compelling features, it has been employed number of studies evaluate and compare different classifiers. In this work, we explore AUC unsupervised domain, more specifically, context cluster analysis. particular, elaborate on use an inte...

Abstract: The receiver operating characteristic (ROC) curve has been extended to survival data recently, including the nonparametric approach by Heagerty, Lumley and Pepe (2000) and the semiparametric approach by Heagerty and Zheng (2005) using standard survival analysis techniques based on two different time-dependent ROC curve definitions. However, both approaches do not involve covariates ot...
