Scoring - Using Classification models

Dears,

i will try to build a scoring model using Rapidminer (Classification Models). is it possible in rapidminer to have score like below for each significant variable? so the higher the score is the more the predicted value will be a YES.

example

Attribute	Condition	Score
Age	18 < x<=30	6
Age	>30	-2
Domiciliation	Yes	5
Issurance	No	-2

For example in this case if the age is between 18 and 30 and the customer has a conciliation (flagged as yes) the customer score will be 11.

Thank you ,
Mario

Hi @mario_sark

There is no default method or operator to produce a table like this unless you assign scores manually.
My question here is, however, what is the expected input and output of a classification model you mentioned? What kind of a dataset do you want to start with?

Your example looks more like a traditional scoring card where each variable value (Yes, No) or bin (18-30, 30+) is assigned a specific score value, and those are summed up afterward. How do you plan though to come to certain variables binning and assigning scores?

Thank you for your reply, actually the idea is generating scores instead of Coefficients. The aim is to target customer who do not has deposits and have the same behavior like those who has deposits.

Multiple variable we will take into consideration such as: Age, Domiciliations, Demographic,... and apply a classification technique to differentiate the two classes and identify significant variables.

As results customers who have scores high with no Deposits we should target them.

I don't know if its possible to generate these scores using RapidMiner.

Thank you,
Mario

Ok, I must admit that I am a bit confused now. So let's break this down a bit

Question 1:

and apply a classification technique to differentiate the two classes

What are the two classes you refer to? In the table above, I see numerical scores, no classes so far.

Question 2: can you please provide a simple example of a) the input you have and b) the output you would like to get. Like one row of data and what you would like to get back for this. Something like that

I am with Vlad here that there is a high likelihood that you are actually looking for something called "Balanced Scorecard" here. RapidMiner could be used for that, but would also be a bit of overkill. Excel is enough for that. But there is also a change that you actually want to train a classification model and are looking for the confidences as output. Hard to tell at this moment, because, you know, see the first line of my response

Cheers,
Ingo

Actually @IngoRM I would argue that using RapidMiner is still better to generate results using balanced scorecards than Excel! For lots of reasons relating to scalability, reproducibility, and auditability of results---e.g., all the reasons why a visual workflow and associated process are better than spreadsheets, where everything is done (generally speaking) manually or is automated in error-prone ways. I think you've actually given presentations on this topic

But certainly it is overkill from the perspective of machine learning, which might not be needed in this instance, depending on what the OP actually wants to do.

Hi @mario_sark

you can easily generate said score with the Generate Attributes operator. It still remains open whether this makes sense in the context of machine learning, a learning algorithm can figure out these scores on its own based on the label, possibly better than the heuristic.
