Shuffling before Training

malalearning

Hi everyone, i would like to shuffle a dataset before the training of an ML model(random forest, light GBM and XGboost), that is simply changing randomly the order of each observation in the training dataset. Is there any method in dataiku to achieve that without using code recipes in dataiku? Thank you all

Hi @malalearning
,

With DSS UI, you can use a sort recipe, generate a random column in computed columns, and then sort by it:

Other than that, if you use Artificial Neural Networks, you do have the option to shuffle between epochs.

I hope this helps!

Thanks,

Jordan
