Yes, decision trees are the latest addition to the suite of modeling techniques supported by ADAPA (to see a list of all techniques click here).
You can build your decision tree model with different training algorithms, export the tree as a PMML file (or convert the resulting model to PMML), and upload it into ADAPA for decisioning.

Even when my model uploads successfully, I still get warnings. Is that OK?
Yes, it is OK. Warnings are generated whenever ADAPA finds inconsistencies in the PMML file which do not affect scoring. However, you should check all warnings even if you get a perfect score match, i.e. your model validates fine.
For example, if you upload the model "Iris_SVM" from the PMML Examples page of the Zementis website, you will get warnings. If you click on the "warnings" hyperlink in the ADAPA Predictive Analytics demo, you will get a file back entitled "uploadedFile.xml". By opening this file in your XML editor, you will be able to see the PMML model you just uploaded with all detected warnings embedded into it as PMML extensions. ADAPA will also generate a comment on the top of the file giving a summary of its findings. For the "Iris_SVM" model, this reads as follows:
Comment generated by ADAPA: There are at least 6 warnings in this PMML document.
Detailed information can be found as comments or as Extension elements embedded in the appropriate locations within this document.
The first warning talks about the timestamp which is not in the right format. For all other warnings look for PMML extensions with name = "WARNING".

Can I upload multiple models into ADAPA?
Yes, you can. The ADAPA Predictive Analytics Edition and the ADAPA Enterprise Edition support deployment of multiple models.
The limited demo version and the iGoogle Gadget demo only allow you to upload one model at a time. Once your model is uploaded successfully, you can use it to produce results/decisions for your data.
If you have a model already in place, it will be deleted once you upload another model. The new model will then be used to produce results against any new data.
If you need multiple models to be available and/or model segmentation, you will need to purchase a licensed version of ADAPA. Please, feel free to contact us at any time if that is the case. Our contact information can be found in the Zementis website, contacts page.

ADAPA refuses to upload my model, what should I do?
Before successfully uploading a PMML file, ADAPA will make sure that it is a valid PMML 3.2 file. During this phase, you may get many syntax errors. All errors need to be resolved before ADAPA successfully uploads a model. Syntax errors (your model is not a valid model according to the PMML 3.2 schema) are displayed as embedded comments in your model file - try clicking on the "details" hyperlink and open the file in an XML editor.
Once your file passes schema validation, it will also be semantically checked (ADAPA will ask: does this model make sense?). Semantic errors and warning are displayed in the model file as embedded PMML extenstions.
If you are using a licensed version of ADAPA through its web management console, errors and warnings are displayed in the console itself.
Use the information you get back from ADAPA to correct your PMML file and give it another try. If you use a PMML element not currently supported by ADAPA, feel free to let us know. You can find our contact information in the Zementis website, contacts page.
