Boosted Model maximum number of trees

I'm trying to build a GBM in Alteryx and the default number of trees is 4,000. The model was still improving based on the this number of trees so I tried increasing it to 10,000, but I'm still not getting the best model.

The maximum number of trees allowed by the tool configuration is 10,000.

Is there a way to increase the maximum number of trees above 10,000?

Hi @Paul_L

You can access within Container 144 inside the Macro, there is a Numeric Up Down Tool, called "The maximum number of trees in the model"

You can change the maximum value allowed for that tool.

That said, I really didn't tried it, and don't know if there is a limitation (for example in R) to have more than 10,000 trees.

Please, let us know how it went.

I didn't get a chance to try out aguisande's answer but it looks good to me. I don't know if they set a limit of 10000 for some reason based on experience/explosion or not.

To save the macro:

When you have it open:

1. Click anywhere on the canvas on then select the Meta Info tab on the properties window

2. Choose Custom under Workflow Name and enter "My BM" (for example)

3. Scroll down to Tool Palette and chose "Predictive" (for example)

4. You can alter the search tags (these find tools when you use the search box)

5. Save the file in a special folder C:\MyPredictive (for example)

6. In alteryx go to Options | User settings | Edit User settings

7. On the macros tab add an entry: Predictive and C:\MyPredictive

you should then see the tool in the Predictive toolset.

I could tell you how to change the icon but I'd have to charge you double.

Cheers,

Bob

Thanks aguisande

I've tried but I'm then having problems saving the macro and if I use save as I'm having trouble getting that to show in my toolbar. Might have to abandon Alteryx for R Studio, which is a real shame as Alteryx is easier for the blending steps beforehand.

Thanks Paul
