Qlik AutoML error: Your experiment failed because the following classes are underrepresented

[Andreas_Giesbrecht]

Introduction

When trying to run a Qlik AutoML experiment you might receive the following error message :

"All experiment versions have errors.
The experiment configuration cannot be edited. Please create a new experiment from the hub.

...
Your experiment failed because the following classes are underrepresented: [...]. AutoML requires a minimum representation of 10 values in each class."

Example:

(the error is reproducible with the attached example data "winequality-red_train.csv" set with target field "quality")

Cause

This error is caused because Qlik AutoML requires that each distinct value in the target column needs to occur at least 10 times.

In this example value 3 occurs in target "quality" only once:

In order to avoid this kind of error please make sure that the data is accordingly represented in the target.
