Today, we are going to introduce a very powerful data mining tool called Rattle. Interesting feature of Rattle is that it is a GUI which sits on top of R. What it means is that it gives users a point and click interface to build data mining projects, predictive Models etc without writing a single line of R code.
In the featured video we have built various predictive models on a credit scoring dataset and compared their performances against each other using ROC curves. Models built are –>
- Decision Trees
- Random Forests
- Adaptive Boosting
- Support Vector Machines
- Logistic Regression
- Neural Networks
This was done without writing any R code (except to launch rattle). Total video lenght is about 17 minutes, which will take you through data import in rattle, variable exploration, model building and model evaluation using ROC’s.
This video is for people from an advanced analytics background as we have not explained much of the methodologies behind the techniques, merely how to do in Rattle. Those who can understand the methodology and are not working in the analytics industry, you should immediately jump ship, greener pastures are awaiting (Seriously, if you understand even 40% of this, you cannot be unemployed!)
For those, who want to understand and learn stuff shown on the video, check out our website www.learnanalytics.in, we specialize in Analytics Training for students worldwide. We provide SAS, R , Advanced Analytics trainings.

To install rattle, simply follow the instructions on the website linked above, if you have problems in installing,drop us a mail, we will be glad to help you out. We will be following up on a detailed post on R and rattle installation with troubleshooting.
Drop in comments to give us feedback!!
This is the best video I have ever seen in predictive modeling; clean and crisp. Looking forward for more videos.
Hi Karan, greetings from Silicon Valley! I was in the process of installing and trying out ‘rattle’ on my Mac, ran into issues in installing ‘RGtk2′, and got linked to your site from TogaWare. Came in to find an answer for a mechanistic question, instead found a gem of fantastic content in your introductory video on ‘rattle’. You exhibit a great ability to ‘teach’, not talking down at students, pointing to exploratory topics beyond the scope of this talk, and looking to convey your overall enthusiasm for the subject. I am tempted to linger / come back for more
Thanks Raj!!
Always feels nice hear appreciation
Hi @ all,
I can tell you why the NN wasn’t created.
The values have to be scaled I[0,1]. (I guess that’s why this option exists.) If you then set the nods at 4 (rule of thumb from sqrt(20)) you get the best result at all.
Very Nice tutorial – didn’t know rattle before,
Claus
Thanks!!
Apart from that I would say the session is nice and self explanatory about the problems of modeling and observation…
I am facing one problem on your given data in csv file. I tried the same but it showed up only two box with no color if I am trying to do box plot distribution either for duration or amount of credit… but as per my understanding it should show 3 boxes one for all other twos for 0 and 1… Please, help on understanding why I am facing problem whether I am missing something…
Note: It showed in data all respective min median/ mean / max are coming accurately as per the demonstration…
Check if all packages have been installed, look into the R console window as all error messages will be published there.
I am not getting any error msg. in the console. When I am starting R, in the console I am getting following msg. about version.

It is not generating any console msg. on producing the box plot distribution of duration.
Everything else looks like same except graphical presentation..
I liked the simplicity of this video tutorial.
Great stuff!! going to try out rattle myself
