I have a dataset from Kaggle (updated). I loaded it into RapidMiner Studio and I would like to prepare a model with Auto Model function. I tried all of the opportunities but these showed the following error:
Error
Process: Support Vector Machine

Answers
I think it is a known bug: the root cause is the parenthesis in the attribute name.
Please remove this parenthesis in the attribute(s) name before submitting your data to AutoModel.
Hope this helps,
