Applying model to dataset et getting output file

Jh_Doe

Hi community, 

 

I'm using RM for a couple of weeks to solve a business case. 

I've used "Auto Model" to loop for the best model to use. 

The design view is well filled with the model template.

 

Now, how to apply the model in order to fill the predicted value to a fresh dataset according to the Designed process ? 

 

Thanks

Hi @Jh_Doe,

 

 - Drag and drop an Apply Model operator in the "Process view"

 - Connect your test dataset (unlabeled dataset) to the uni input port of Apply Model operator

 - Connect your model to the mod input port of Apply Model operator

 - Connect the output ports (mod and lab) of Apply Model operator to the res ports.

 

Here a simplified example of process : 

 

The XML file of the process :
