System and method for degradation based on survival analysis warning model

A detection modeling system has a processing device and a memory coupled to the processing device. The detection modeling system is configured to select a detection model for evaluating model degradation, the detection model being an analysis model for analyzing data and identifying a target event, perform a survival analysis on a plurality of similar detection models, determine a survival metric for the selected detection model based on the survival analysis, and determine a target event for the selected detection model based on the determined survival metric. And comparing the survival metric to a threshold and alerting model degradation based on the comparison. 一种检测建模系统具有处理设备和耦合到该处理设备的存储器。检测建模系统配置成选择用于评估模型降级的检测模型，检测模型是用于分析数据和识别目标事件的分析模型，对多个相似的检测模型执行存活分析，基于存活分析确定选择的检测模型的存活度量，并且将存活度量与阈值进行比较并且基于比较警告模型降级。
