Performance Metrics

Hello
Does anyone in the community have any idea how to generate 'custom performance metrics' in RapidMiner? I'd be grateful to know.
The list of metrics ("recall", "accuracy","F1 Score", etc) does not include "Balanced Accuracy" or "Balanced Error Rate". Yes, I can manually calculate these, but there must be some simple way of generating them post execution?
ChatGPT and CoPilot suggest using the "Generate Attribute" operator, but it fails to recognise the metrics mentioned above. Wasted ages so far trying to achieve this. 😓

    Hi @Quixote01,

    I would agree with ChatGPT and CoPilot - you would have to use "Generate Attribute" and write your own formula to calculate those - that's what Generate Attribute does - it allows you to use your own formula to specify the value of an attribute.

    It would be interesting to ask ChatGPT to write the formula for you, at least as a starting point.

    Hope this helps.
