Training Decision Tree: Get RSDME362

Hi,
I want to train my decision tree modell and get an error: RSDME362, Vorhers. Modellf. hat nur einen Wert.Daten können nicht trainiert werden.
If I look at the statistics of the attribute which will be predicted it has two distinct values: 1.000 and 0.000.
Does anybody knows what could be wrong??
Thanks,
regards

Hi,
I found the problem: the algorithm couldn't process values with 0. So we changed it to 1 (=yes) and 2 (=no) instead of 0 (no).

Plotting a Trained Decision Tree Model

Is it possible to plot an Azure based decision tree similar to what is done in R? That is, a mapping of the splits at each node level with summaries in each of the leaf nodes. It is helpful info to understand how the tree is splitting but even
more helpful in providing the client with a decision path that they can follow.

Hello,
Unfortunately not - this is feedback we've received and are working to implement on many of our learning algorithms: improved visualization/transparency into their details.
We'll report back as we make progress on this!

Regenerate decision tree for transfering to unicode system.

Hello,
We upgraded the system to a unicode system and we're getting runtime errors using PB infotypes (pb20/pb30) for the
generated forums in the decision tree.
The error thrown is unicode compatability, If I make a "false" change in a certain decision tree for a field, the form is regenerated and It works.
The problem is , that I have over 200 fields for decision trees, and I need them all regenerated.
Someone gave me report "RPUMKG00" as a solution (activation type 1), but It does not regenerate the forms in a unicode mode.
does anybody have any ideas?
thanks.

What is a Decision Tree Algorithm?

hi there,
what is a decision tree algorithm??

Hi,
Decision trees are used to learn from historic data and to make predictions about the future. Prediction involves establishing rules using historic data and applying these rules to new data. These rules are displayed graphically as a hierarchy.
Ex : Your customer data typically contains attributes such as gender, age, income, region, and occupation as well as information about whether a customer is a satisfied customer or not (possibly drawn from a survey). You can use such historic data to train a decision tree. You find out as a result that customers exhibiting certain attributes are generally satisfied customers while customers exhibiting other attributes tend to be dissatisfied customers. You can use rules determined in this way to assess the satisfaction of other customers in cases where this information is not available.
Integration :
The data that you use to train the model can be taken from any other system, provided that the system can extract data into SAP BW. Similarly, you can apply the identified rules to any data that has been extracted into SAP BW. In SAP BW, you can use queries to access data with known statements and then use this data to find out statements about other data.

Decision Trees with ODM 10.1

Hi all,
Does anybody know how to use DTs with ODM R1?. Maybe with the ABN model?.
Any hint or recommendation to start with this?
Thanks in advance!

In ODM 10.1 you can get a type of decision tree using ODM in single feature mode. Unlike a traditional decision tree algorithm (e.g., CART), this type of ABM model creates a tree that, for a given level of the tree, it splits all the nodes along the same attribute. This ABN approach has the advantage of being more robust than traditional decision tree models. However, it works better (more accuracy and deeper trees) if the data set has a large number of rows.

CSTVI decision tree

Hi All,
can any1 plz help me how to create CSTVI decision tree.
Is it compulsory to create CSTVI, CRDVI,COVGR,EECGR decision trees& why do we create them?
Thanks,
satya

1. You can read more about the algorithm at
http://technet.microsoft.com/en-us/library/ms175312.aspx ,
http://technet.microsoft.com/en-us/library/cc645868.aspx
2. You don't need to write code to use algorithms from SQL Server. If you are just getting started, I recommend you to use Excel Data Mining Add-ins to create the models
http://www.microsoft.com/en-us/download/details.aspx?id=35578
If you don't have Excel, you can create models from SQL Server Development Studio, but it is more difficult to use.
What are you trying to do?

Classification - decision tree - build result - empty tree

Hi,
Using "Activity/Build" wizard (data miner beta3), selected "classification"/"decision tree", and "default" on all other screens. The "Build" looked successful. But when I selected the "Result" link under the "Build" section from the result page, it poped up a "Result Viewer" window, with a blank page (frame) under the "Tree" tab. I assume a "decision tree"should be created and viewable under the "Tree" tab. Any idea what is wrong?
Thanks,
Jack

Hi Jack,
I think this is a known bug, but can you verify that for me?
If you launch ODMr using odminer.exe, you will also get a console window.
Now go to the tree result and try to view it.
See if the following exception displays in the console:

I created a node for molga: 40, on 40: my Personnel area and under that sub area, on sub area , value 01 to Specify Rule Groups for Quota Type Selection
Please help.

ODM Decision Tree result

I am using Oracle Data Miner with an Oracle 10g Database. I would like to know if there is a tool or a plug-in for ODM to watch the Decisional Tree, resulted of executing the Decision Tree Algorithm, as a tree. Could you help me?
Thanks in advance!
.javier

HI Javier,
I know I responded to your internal email on this question but I will respond here as well for the OTN folks.
ODMr 11 will be providing a full decision tree graphical viewer.
ODMr 10.2 does not have any plugin capability.
It is quite reasonable to implement a decision tree viewer of your own, the first step would be to locate a diagram tool that meets your needs and then use the ODM api to get the detail data.
ODM also has partnerships with Inforsense and SPSS(Clementine) that do have dt viewers but I am not sure if they have fully integrated them for ODM yet.
Thanks, Mark

Thank you.

After setting system language to English, be sure to restart SQL Dev to retry the test.
Make sure you have the latest patches installed.
Go to menu: Help-> About. In the About dialog, select the Extensions tab and check if you have Data Miner version 11.2.0.2.04.40. If not, go to menu Help->Check for Updates, and install the SQL Developer and Data Miner patches.
SQL Dev 3.0 is not certified with Java 7.
Thanks,
Marat

How to create a decision tree in ABAP (in SAP or not, and how????)

Hello,
I have to create a decision tree which has to be called within a BAPI.
This tree finally has to return 1 single value.
Can you tell me what's the best solution for this ?
Should I do this with abap, or should I call a webapplication which provides this tree for me ?
It would be great if you could provide some example-code for me.
Kind regards,
Gert-Jan

I am not sure I understood what you meant by decision tree. If you are simply talking about arriving at an answer based on one or more inputs, then it is a simple IF ELSEIF ELSE statements or CASE statements.
Can you please elaborate/give example of what you mean by decision tree?

Problem in Exploring the Decision Tree Model on Lesson 4 Basic Data Mining SSAS

Hello everyone,
I've tried to follow all the steps mentioned in Basic Data Mining Tutorials, but I've an odd problem in the Lesson 4 - Exploring the Decision Tree Model (http://technet.microsoft.com/en-us/library/cc879269.aspx).
It's stated that "As you view the TM_Decision_Tree model
in the Decision Tree viewer, you can see the most important attributes at the left side of the chart. “Most important” means that these attributes have the greatest influence on the outcome. Attributes further down the tree (to the right of the chart) have
less of an effect. In this example, age is the single most important factor in predicting bike buying. The model
groups customers by age, and then shows the next more important attribute for each age group. For example, in the group of customers aged 34 to 40, the number of cars owned is the strongest predictor after age."
But, I got a different result from what mentioned in the tutorial. I got the number of cars owned as the most important attribute, then followed by the attribute age.
Do you guys know why?
Thanks in advance

HI,
BEGIN
INSERT INTO DT_CA_SETTINGS_TEST (SETTING_NAME, SETTING_VALUE) VALUES
(dbms_data_mining.TREE_TERM_MINPCT_NODE,to_char(1));
END;
That is not "Mode" its "NODE".
Now Execute.
Cheers..

None of the commnets or other type of annotations on this page are contained in the structure tree, getting this error on full check of adobe acrobat PDF

none of the commnets or other type of annotations on this page are contained in the structure tree, getting this error on full check of adobe acrobat PDF

You can find and tag the unmarked annotations using the Tags pane - click the down arrow next to
the Options icon (near the top left of the pane), then Find > Unmarked Annotations. You will be given the option to tag the annotations - usually they are hyperlinks in which case use the link tag. Then you will need to create the proper tag stucture. Lots of information about that via google, for example the Adobe Acrobat X Professional: PDF Accessibility (Section 508 Tagging) Reference Guide (http://webtools.ca.gov/files/2010/07/acrobat_X_tagging-manual.docx)

In cloud for service, is there a way to generate RMA's and decision trees?

Also, where can I find more information on the field service capabilites?

Yes it is supported via HCI configuration. C4Service provides a standard iFlow that creates a follow-up SD Order (Billing Request) from a C4Service Work Ticket. You can easily reconfigure the iFlow using HCI tools to create a SD Return Order instead of a SD Billing Request. This would then allow you to easily configure the C4Service work ticket to be a RMA capture form so that an end user can capture the products/parts as items for the SD Return Order (RMA). The end user can then release the Work Ticket to ERP which would create the RMA and ERP would take over the RMA process.
As for the decision tree, this is supported using dynamic checklists and surveys for tickets. You can configure a dynamic survey/checklist that can have a series of questions that based on questions answered in the previous step can have different follow-up questions. These surveys/checklists can instruct the end user through a series of questions to help them diagnose a problem to ultimately instruct the end user to release the work ticket to SD for a Return Order (RMA).

How to find optimal multi splits for numerical attributes in Decision Tree

Hi experts,
I would like to know how to find optimal multi splits for numerical attributes
in Decision Tree Learning.
For splitting categorical attributes, gini and gain index are used and the splits that
produce the best gain are selected.
However, in case of numerical attributes
how do you find the best splits?????
Please help me !!

Yordan's suggestion is correct, though the documentation is a bit outdated.
You can use the single parameter + sweeper mode or define your own custom ranges in the BDT module with the Parameter Range setting
