PerformanceEvaluator

Full name Microsoft.VisualBasic.DataMining.Evaluation.PerformanceEvaluator Assembly Microsoft.VisualBasic.DataMining.Framework Members 6

Class which evaluates an SVM model using several standard techniques.

00 Remarks

该类型来源于 SVM.NET，当前在仓库内没有调用方。其 ROC/AUC 计算已经统一委托到 RocBuilder / PerformanceEvaluator.AuC 核心实现，保留该类仅为向后兼容。
