Multi output random forest regression

Hi All, 

is it possible to create a multi output random forest regression using a visual analysis ?  AFAIK you only can select one feature at a time to be predicted.

I don't know if subpopulation analysis is the way to go here or it must be done via code recipe.

Thanks

I will reformulate the question 😀

Having a dataset with the following shape:

- Training X_train : (33873, 17) y y_train :(33873, 15)
- Validation_1 X_test : (14517, 17) y y_test : (14517, 15)
- Validation_2 X_test2 : (145973, 17) y y_test2 : (145973, 15)

So, let's going to predict 15 values using random forest regressor. is it possible to do that using  visual analysis ?

Thanks

Hello,

You are correct, it is not possible to build a multi output model using a visual analysis. You can however create a custom model.

To do this in DSS:
