ACE_ML017 - Details

• The SAP error message ACE_ML017 indicates that the class distribution ratio in your dataset is not meeting the minimum requirement of 10%. This error typically arises in the context of machine learning models, particularly when you are trying to train a model that requires a balanced dataset across different classes.
  
  Cause:
  The error occurs when one or more classes in your dataset have a representation that is less than 10% of the total instances. For example, if you have a dataset with 1000 instances and one class has only 5 instances, that class represents only 0.5% of the total, which is below the required threshold.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Data Collection: Increase the number of instances for the underrepresented classes. This may involve collecting more data or augmenting existing data.
  
  
  Resampling Techniques:
  
  Oversampling: Increase the number of instances in the minority class by duplicating existing instances or generating synthetic instances
