Hi @maryamen69

Calculate the Mean Absolute Error is only possible if you have the "true labels". (you are comparing the "true labels" to the "predicted labels")
This is a priori not the case for unsupervised learning like clustering.
If not you can use the Performance (classification) operator...

Hope this helps,

Hi again @maryamen69,

Or maybe I misunderstood, by Mean Absolute Error you mean Average within Centroid distance ?
In this case, you have to use the Cluster Distance Performance operator.
