System information

  • OS version/distro: ML.Net 1.5.1
  • .NET Version (eg., dotnet --info):

Issue

  • What did you do?
    We use the API DetectEntireAnomalyBySrCnn

  • What happened?

We see some points are outside of the confidence bound yet not detected as anomalies. This is a bit confusing on why these points are not anomalies.

  • What did you expect?

The non-anomaly points should be included in the confidence bound.

Source code / logs

PR: #5374

Proposed change: Adjust the confidence bound so that it includes the non-anomaly points
