[-]Changes to Anomaly Detection[/-][+]DetectEntireAnomalyBySrCnn - No anomalies detected as of version 1.5.4 or greater[/+]on Jul 28, 2021 @luisquintanilla since this is a regression I would say its probably a higher priority. @briacht thoughts?
Yeah if the algorithm isn't working anymore we should definitely try and fix that
This is the PR that caused this bug #5202.
The current tests use sensitivity 87 nor 64 (
test/Microsoft.ML.TimeSeries.Tests/TimeSeriesDirectApi.cs)This sample program should be updated https://github.com/dotnet/samples/blob/main/machine-learning/tutorials/PhoneCallsAnomalyDetection/Program.cs
The code itself was fixed in #7610
System Information (please complete the following information):
Describe the bug
When using
DetectEntireAnomalyBySrCnnwith versions 1.5.4 or greater, no anomalies are detected when running theDetectAnomalymethod from the phone call tutorial.Changing options does nothing. Has anything changed with this algorithm that would suddenly make it stop working after 1.5.4?
If you run the sample using version 1.5.2 with the same data and options it works.

To Reproduce
Follow the steps in the phone call tutorial. For reference, here's a completed code sample
Expected behavior
Anomalies are detected.
