Creating If Statements in RapidMiner
Learner III
The problem I face is what algorithm is the best one to use for my experiment.
iHi,
I am new to RapidMiner and would like to know if there is a way to create your own rules within the application.
I have imported a CSV file and tried all the built in algorithms but none of them give me what I need to achieve. My problem is outlined below, which I can achieve using excel if I need to.
Rule 1: Using election data, see if candidates need to be in the frame after the first count. That is if there are four seats in any election and 8 people running, the first 4 people after the first count win the election. I refer to an Irish election where people can vote by preference meaning that they vote 1,2,3 etc.
The only way I can think of proving this, is to firstly sort the result column into ascending order and add a counter to the column.
If Rank <= (Seats) and ActualResult <> Yes Then
Concept Class = Win
Rule Accuracy: 100%
ElseIf
Rank <= (Seats) and Elected = No Then
Concept Class = ExceptionToRule
ElseIf
Concept Class = Loose
Rule Accuracy: 100%
End If
Any help or guidlines of where I can find informaton on building my own mode would be greatly appreciated.

you are right, that way it is doable:
1. Sort the data with the Sort operator
2. create an Id with Generate Id
3. Use Generate Attributes to create a new attribute based on your rules
Best,
