我正在查询 Azure Custom Vision V3.0 培训 API(请参阅https://westeurope.dev.cognitive.microsoft.com/docs/services/Custom_Vision_Training_3.0/operations/5c771cdcbf6a2b18a0c3b809),因此我可以通过自己生成每个标签的 ROC GetIterationPerformance 操作,其部分输出为:

u'perTagPerformance': [{u'averagePrecision': 0.4887446,

precisionStdDeviation
准确率和召回率的不确定性recallStdDeviation
分别似乎总是 0.0。这是用户错误吗?如果没有,是否有计划激活这些统计信息?
