Thank you! i’ve been searching for this for a long time.

I have one question, what is the use of the k-means ? is it important !?

It is one of the most widely used machine learning algorithms in use today. There are different variations of it for data of different sizes, formats, etc.

Thanks bro!

What is the name of distance calculation used in the program?

euclidean distance

svp le code k-means en utilisant la recherche locale svpp trés urgent help 🙁

Svp le code duPAM Partitioning Around Medoids

Algorithme de clustering

urgent ..

We have trouble with code on linux for it is showing . h file directory not found

Its saying iostream.h file or directory is not there

Do not use .h only #include
