Auto Model

[Deleted User]

Hi there
Would you please tell me how can I change the predictive algorithm in َAuto Model?
I mean that: how can I use spesific algorithm that I need except  algorithms that we have in Auto Model?
Bcause this is the first time that I use Rapidminer.

AutoModel is limited to a specific set of algorithms that are chosen because they work well in a wide variety of use cases and can be applied automatically through the wizard interface.
If you need a specific modeling algorithm that is not one of the preselected choices, your best bet is to use AutoModel to generate a model, then open the actual process associated with it, and then change out the learner algorithm manually.  This may then require you to select additional model parameters depending on the algorithm chosen.

Hello @mbs

As mentioned by @Telcontar120 you cannot add more models directly into Auto Model. But you can open any model in automodel by clicking open process and copy the XML of that process. You can find XML code by going to View--> Show Panel--> XML. Once you copy the XML code from XML window then open a new blank process window and paste this copied code in the XML window of a blank process. Click on the green tick mark on XML window, this shows you the operators in the process window. Here you can change the model you want and add some parameters related to that model.

Thank you for you're suggestion. Would you please explain it more? Especially this part: " your best bet is to use Auto Model to generate a model, then open the actual process associated with it, and then change out the learner algorithm manually.  This may then require you to select additional model parameters depending on the algorithm chosen."
sorry I couldn't understand it completely.

I also would recommend to go through the in-product tutorials under the menu Help - Tutorials.  These are designed to teach you how to build and edit processes (which would be necessary for this).  Also this course here (and the other materials in the Academy) are likely to be helpful: https://academy.rapidminer.com/learning-paths/get-started-with-rapidminer-and-machine-learning

If you struggle with any of this, I would actually recommend to NOT try and do this but just go with Auto Model instead.  The models in general work well on a large variety of use cases and data sets and it might not be worth the efforts to try different models just to get 0.5% more accuracy (or something like that) ;-)

Just my 2c,

Ingo
