No sorry, I believe that is only for a single decision tree, not a gradient boosting machine model.

You can see if there is a more informative error message in the SAS log. Right-click on the node and select Results, then go to View>SAS Results>Log. If you search for "ERROR:" (with the colon in quotes), you might get more information about the error.

That should work - can you open the results of the Decision Tree node and see if there is a more informative error in the SAS log?

Your diagram looks fine to me assuming you have all of your data roles set correctly... If you open the SAS log from the results of either of the failing nodes (open the node's Results, go to View>SAS Results>Log), do you see any more informative error messages?

If nothing has changed in a node before the Neural Network and Rerun isn't set to Yes in the Input Data node, I wouldn't expect the node to re-train (though you might see it spin for a few seconds then turn green).

The thickness/boldness of the lines only indicates the proportion of observations in the training data that follow that path. For observations that meet the rules that follow your red line, that is the branch that will be used when scoring those. Does that make sense?

In the Input Data node you have for your TEST data, do you have the Role of the data to be Score? This indicates that this is data that doesn't have the target in it, and is what you should be using. If you do already have that set, then I will probably have some other follow-up questions, but thought I'd check that first.

Can you provide some more detail about the specific nodes in your flow?

You can see if there is a more informative error message in the SAS log for the Start Groups node by right-clicking on that node and selecting "Results", then viewing the SAS log under View>SAS Results>Log.

Starting with version 14.1 of SAS Enterprise Miner, there is an HP BN Classifier node available from the HPDM (high-performance data mining) tab of nodes that can run a Naive Bayes model (among others).

Yes!

You would need to do it in a SAS Code node. Here is example code to impute Age with its mean within each level of TravClass: proc means data=&em_import_data mean stackodsoutput; class TravClass; /* change this to name of class variable, here and below */ var age; /* change this to name of age variable, here and below */ ods output summary=outmean; run; proc print data=outmean; run; filename flow "&EM_FILE_EMflowSCORECODE"; filename pub "&EM_FILE_EMPUBLISHSCORECODE"; data _null_; set outmean end=last; file flow; if _n_=1 then do; put "if AGE = . then do;"; put " if TravClass='" TravClass "' then "; end; else do; put " else if TravClass ='" TravClass "' then "; end; put " IMP_AGE = " mean ";"; if last then do; put "end;"; put "else IMP_AGE = AGE;"; end; run; %em_copyfile(infref=flow, outfref=pub);

I prefer DATA step to SQL, but there is probably a way to do it with SQL too 🙂 data work.test; set &em_import_data; drop %em_rejected; run; Note for this to work, you need to set the Hide Rejected Variables property in the Variable Selection node to No, then in the Variables editor for the SAS Code node, set Use=Yes for all variables.

The only thing you can do is download the batch API code for a project. You can see details for how to use that here: https://go.documentation.sas.com/?docsetId=vfug&docsetTarget=p0inhev90m1kkcn1xwsaiuhjnv2f.htm&docsetVersion=8.3&locale=en#n194n9wnp2xokzn15f9gwn3ejtjo (this doc is for Visual Forecasting, but same information applies for Visual Data Mining and Machine Learning).

Can you clarify if you mean the training code or the scoring code?
