Add anomaly detection after MFE

I wanna add anomaly filter after feature extraction for my project, then I found this Anomaly detection on audio data - Blog - Edge Impulse but I cant find the anomaly detection here, is this feature removed? or anyone have idea how to filter anomaly sound

Hi @alvinzulham,

The current anomaly block for audio data was removed some time ago as it doesn’t work well well high-dimensional data.
What I’ll suggest is to create an anomaly class with random sounds/keywords that are not part of your other classes. Once deployed, you can add a check in your embedded application on the predicted label and filter out the anomaly class.
