script to create a set derive field node..

Hello everybody,

I'm a newbit in Clementine and have a little difficulty to solve, so I propose you to consider it ;-)

I'm writing a script in a stream to create a set derive field node.
No problem with the beginning but with the condition.
It's about something like that :


set derivenode.set_default = 0
set k = 1
set LIST = [12 34 56]
for Capa in LIST
   set derivenode.set_value_cond.1 = "Kant = ">< ^k " and Nb < ">< ^Capa
   set k = k + 1
endfor

As I run the complete script, I only ge the final line in the set derive node :
set :   1                Condition :    Kant = 3 and Nb < 56

But I want to obtain this :
set :   1                Condition :    Kant = 1 and Nb < 12
set :   1                Condition :    Kant = 2 and Nb < 34
set :   1                Condition :    Kant = 3 and Nb < 56

If someone have an idea, it will be great to indicate the way to find a solution.

Thanks a lot

David

P.S. : Thanks a lot to Mister TimManns for is v9_ClemScript.txt

Artificial Immune system with data mining

Hi there!

Since Artificial Immune System is quite a new method in AI, I wonder if anyone here apply it to data mining?

Or does anyone here have similar algorithm or any source code?

cuz I'm self-learning AIS and found it hard to learn without some examples.

Back propagation in Neural networks
I'm doing a project in forecasting using Neural networks with multi-layer back propagation algorithm. Can anybody suggest any point from where to start, considering I am new to neural networks. Also is it possible to do it in C++? Any suggestions are gratefully accepted. Thank you

Using scripting to automate model building/testing

I'd like to write a script in Clementine that would build and test a model using every possible combination of options in the C5.0 algorithm.  That would allow me to look over the results and select the most appropriate set of options.

 Is that possible?

Expression - Checking if field is lower case

I have a field which contains a list of surnames and I would like to check whether the first letter of this field is in lower case.  I have tried islowercode(subscrs(1, 'Surname')) but this returns an error: Invalid Type for Field : BOOLEAN.

Is there any other expression that I can use?

I have also tried deriving a new field that just contains the first letter of the field Surname and using islowercode(Derive1) but this also doesn't work.

I know this is probably pretty basis, but I am new to this...if anyone has any other forums I could use for this type of question, that would be a great help also.

Kind Regards

Carly

I have all together 15 symptoms for predicting the disease and I have about 300 patients records.I am using vc++ for implementing the network.Before starting to implement the network I am confused.I dont know how many hidden layers to be used and how many nodes.

Can anyone help me deciding this.

Derive new field 'New_Date' = 'Event_Date' - 60 days.

Greetings:

I have an 'Event_Date' field in the date and I need to create a new date field where  'New_Date' = 'Event_Date' - 60 days.  In other words, I need to derive a new variable that is 60 day prior to "Event Date".

I have been struggling with this for about 4 hours reading the manual, trying different formulas and keep hitting a wall.  If you could lend a hand I would be very grateful to you.

 Cheers:

Patrick

FPMiner: a frequent pattern miner using Apriori and FPGrowth
Hi guys, i'm an italian MSP student and with a colleague of mine i've developed an open source project hosted on codeplex called FPMiner; we've implemented firstly a classic basic brute force version of Apriori, secondly an Apriori optimized version based on hashtree and scoring map and finally the huge FPGrowth method. You can find it here http://www.codeplex.com/fpminer Every constructive critique and improvement will be accepted, and if you want you can contact me if you want to partecipate to the project.
