Can I use the 'Model Simulator' operator using a model from the 'Multi Label Modeling' operator?

kimjk3559

We were able to successfully obtain predicted values for data with two labels (labels independent of each other) using the 'Multi Label Modeling' operator.

However, when I connect to ‘mod’ of ‘Model Simulator’, a ‘Wrong Model Type’ error message appears.

Ultimately, I wanted to set specific target values for the two labels and check the values of the remaining variables. Is there another way?

Hi,

the model simulator was build to only show one model, it does not work with a multi-label one.

There is actualy no operator to extract a single model from the multi-label one which you can then use. I've created a small script which does it for you. I hope that helps!

Best,

Martin
