I built a custom CHAID tree in SPSS modeler. I would like to assign the particular terminal nodes to all of the records in the dataset. How would I go about doing this from within the software?
Assuming that you used the regular node called CHAID, if you select inside the diamond icon (created chaid model) in the tab configurations the rule identifyer, the output will add another variable called $RI-XXX that will classify all the records within the terminal nodes. Just check that option and then put a table node after that and all the records will be classified.
You just need to apply the algorithm to whatever data set you need, and you only need to inputs to be the same (type and eventually storage).
The diamond contains the algo and you can disconnect it and connects to whatever you want.

I am trying to make my SPSS flow a bit more dynamic. Although there is no way (that I am aware of) to take an input, is there a way to use User Input node to take some parameter values and use these parameters in another select node to perform tests on data.
What I am trying to achieve is run the same flow with some minor parameter changes. I have the flow running for some static values used in select nodes. It would be great if there was a way to change these static select nodes, even if it's not with a User Input node.
I believe what you are looking for is actually to make a parameter in SPSS modeler and then enable/check the Prompt? which will ask the user for input every time the stream is executed.
In SPSS Modeler 18.2 onwards I was able to see the prompt option as the first feature of parameter tab.
During the creation of a generalized warehouse model, I ran into a problem when trying to create an order event that can be used by order pickers to retrieve the products from the storages racks. Currently, I am using a source block which creates "orders" of a single type of pallet (1 to 5). The pickers each travel to pick up a pallet from the rack and transports them to the next location.
Question: How can I create an order consisting out of several pallets consisting of different types.
Question: How can I use a single picker (resource) to pick multiple pallets in a single run through the warehouse before transporting all the pallets to the next location (process).
Kind regards,
Stefan
Question 1
normally i would create a class for the higher level order (say Pickwave class).
And when instantiating it you need to save a list of actual picking orders(pallets) into it (say collection of type ArrayList<Order>).
And to process your pickwave you can use a loop which will steer your resource/transporter/picker to the next Order location until all orders are picked. If everything is picked you exit your loop and move to your next location
Question 2
you don't really pick the orders as you would normally pick them using RackPick block in 1-to-1 scenario. But as you have a refence to all your orders inside you pickwave object you can still control their location/animation programmatically.
I am on Enterprise Architect 13.5, creating a deployment diagram. I am defining our servers as nodes, and using attributes on them so that I can specify their details, such as Disk Controller = RAID 5 or Disks = 4 x 80 GB.
When dragging instances of these nodes onto a diagram, I can select "Set Run State" on them and set values for all attributes I have defined - just like it is done in the deployment diagram in the EAExample project:
Since our design will have several servers using the same configuration, my plan was to use the "initial value" column in the attribute definition on the node to specify the default configuration so that all instances I create automatically come up with reasonable values, and when the default changes, I would only change the Initial Values on the original node instead of having to go to all instances:
My problem is that even though I define initial values, all instances I create do not show any values when I drag them onto the diagram. Only by setting the Run State on each instance, I can get them to show the values I want:
Is this expected behavior? Btw, I can reproduce the same using classes and instances of them, so this is not merely a deployment diagram issue.
Any ideas are greatly appreciated! I'm also thankful if you can describe a better way to achieve the same result with EA, in case I am doing it wrong.
What you could do is to either write a script to assist with it or even create an add-in to bring in more automation. Scripting is easier to implement but you need to run the script manually (which however can add the values in a batch for newly created diagram objects). Using an add-in could do this on element creation if you hook to EA_OnPostNewElement.
What you need to do is to first get the classifier of the object. Using
Repository.GetElementByID(object.ClassifierID)
will return that. You then can check the attributes of that class and make a list of those with an initial value. Finally you add the run states of the object by assigning object.RunState with a crude string. E.g. for a != 33 it would be
#VAR;Variable=a;Value=33;Op=!=;#ENDVAR;
Just join as many as you need for multiple run states.

I want to use Weka clustering algorithm XMeans. However I cannot figure out how to obtain cluster assignments from GUI of Weka.
At the moment I can only see a list of cluster IDs along with percentage of entries assigned to each cluster.
Question
There any way to save cluster assignments for each entry in, e.g. CSV format?
Do everything in the "Preprocess Panel".
This is one way to do this:
Load Data File.
Remove any Classification Attribute or Identifiers
Choose Preprocess / Filter / Unsupervised attribute Filter /
AddCLuster
Click on the Word "AddCluster", choose the XMeans Clusterer, click
Apply.
This sghould add a new column "cluster" in the Attribute Panel
Click on "Save..." Button to export.
i'm creating some BIRT-Reports with Eclipse. Now i got the following problem.
I've got two datasets (Set one named diag, set two named risk). In my report i produce fpr every data in diag a region with an diag_id. Now i tried to use this diag_id as input parameter for the second dataset (risk). Is this possible, and how is this possible?
To link one dataset to another in BIRT, you can either:
Create a subreport within your report that links one dataset to another via an input parameter - see this Eclipse tutorial.
or:
Create a joint dataset that explicitly links the two datasets together - see the answer to this StackOverflow question.
Alternatively, if both datasets come from the same relational database, you could simply combine the two queries into a single query.
If you are using scripted data sources, you could use variables.
Add a variable through the Eclipse UI called "diag_id".
In the fetch script of diag, set diag_id:
vars["diag_id"] = ...; // store value in Variable.
Then, in the open script of risk, use the diag_id however you need to.
diag_id = vars["diag_id"];
This implies that placement of risk report elements are nested inside the diag repeating element so that diag.fetch will happen before each risk.open.
