Cross-Validation LoopX-Aggregator is kind of pointless in my opinion. So here an example to get more meaningful metrics for each split. Of course youneed to adjust if you are interested in different metrics.Normalization and SMOTE must only be applied to Training Data.In the real-world you would actually run a cross-valdiation on each set of parameter in case you are doing a parameter optimization.The way it is now will simply give you an idea if you can build a useable model (doesn't look like that at all) and how much the modeldepends on the input data ( a lot, very high variance between models).
