Hey, I am working on a decision tree.

HIMANI

 I am new to rapidminer. Just wanted to know if I am going  right or not. My dataset is very complicated that I cannot find any ways to make comparison. I also need help with linear and logical regression. I have to do the classification of the data and validation with a yes no attribute followed by KNN.

Can anyone help me?

Hello,

Can you explain the problem first?

I would suggest the easy method of applying Data Science:

• Retrieve your data.
• Split it in a stratified way, 0.8 of your data for training, 0.2 for testing.
• Connect the first port of the Split Data operator to your algorithm (almost any prediction algorithm can do).
• Connect the mod port of your algorithm to Apply Model.
• Connect the second port of the Split Data operator to Apply Model.
• Use a Performance operator to check how things go.

This is how it looks:

Please, find a model attached to play a little. I imported your Excel and made one change: the role is setup by hand, rather than using the Set Role operator. I did it like that because I'm lazy.

Rodrigo.

I am trying it, thanks for the response.

I am not getting it and I cant get access to your file(I tried importing it from downloads but it doesn't work), I have the least knowledge of rapid-miner. Also I dont get the stratified part, how to do that after setting it to stratified samples?
Here I am stuck with this problem and even if I set it to work-class by adding a set role operator, the results which I get are not understood by me.

Hi @HIMANI ,
First of all what you have to do with xml code, is to open it with an editor, copy the code and paste it into design.
Secondly, if you visit rapidminer.com you will find many tutorials.
https://academy.rapidminer.com/learning-paths/get-started-with-rapidminer-and-machine-learning
In that link you can see how to do the first steps into rapidminer.
As you can see there is also an example with a decision tree model :

Hope it helps.
