Mustafa Ali Abuzaraida

Dear Hooman,

I think you need to use a software to analyze your data. Like Weka, Orange or other platforms to do some experiments to find the best algorithm and the number of clusters.

Hooman Firoozi

Dear Mustafa Ali Abuzaraida

Thanks for your answer. Do you know how WEKA or ORANGE work?

Are they open source?

Thanks again.

Yes, they are open source. They provide many data mining techniques. Many videos are available to learn how to use them. Good luck

Thank you so much.

Good luck.
