RE: K-means clustering using native functions

Thanks for the email Alf.=0A=

You are totally right, there are multiple tools available to perform any ma=
chine learning or data mining analysis such as k-means with in many advance=
d forms. One of them is weka, which I used recently and is open-sourced. An=
d just like weka, there are many others. =0A=
=0A=
Let's say I would like to perform a k-mean clustering using native function=
s mainly for academic purposes. I know there might be a significant negativ=
e impact on performance, at least in comparison with in-memory like tools.=
=0A=
=0A=
So, this is why question still remains open. I would like to stick to or di=
scard the possibility of implementing a k-mean clustering algorithm using n=
ative functions.=0A=

Thanks again for your reply,=0A=

Hi Caludia,=0A=
=0A=
my experiences with K-Means Clustering shows that it is much faster and=0A=
more flexible than a (direct) database approach to perform it in=0A=
computer memory.=0A=
Usually for the most widely used programming languages still solutions=0A=
(more or less modular) exist.=0A=
Primarily datas path DB -> K-Means Module has to be done.=0A=
