grouping

Juhix

Hi!

I am a beginner so I just started to learn RapidMiner, and I have a question. I have a huge database and I want to simplify my database. I want to create groups. The database contains people data, like AGE of the people. From 18 years old to 100 years old and I want to make 4 group. Age below 20, Age between 21 and 40 years old, 40 to 60 and 61+ etc. What is the easiest way? Could you please help?


Thanks in advance

Hello,

"Groups" as you describe it is not really an aggregation. Basically what you want to do can be done with the "Discretize by User Specification" operator. To not lose the age value, you can also use "Generate Copy" to create a copy of the value, so that you can use it later for further analysis.

Check the attached process.

All the best,

Rod.

Hello Rod,

thanks, it works, perfect. :-) What I do not understand/know is the Attachement. Does RapidMiner have an "engine" where we can type it? Sorry, I just started to use it and still learn it.

Hello Gabor,

Sure. When you get a file with .rmp extension, you can go to File > Import Process, which is the same as opening a file in pretty much every other application.

All the best,

Rod.
