"Is there a metric of evaluation for clustering?"

Marcello_Sandi

Hi,

In the final for clustering process I need a measure that said me how the clustering was good. Is there this measure.

How can I get it?

If this measure exists, how can I interpreted it?

Hi,
there are. As all performance in the Validation group of the new operators tab. Please take a look there.

You can get it pressing the left mouse button while the mouse cursor is above the appropriate entry in the operator selection tree. The hold the button pressed while dragging the operator onto the tree. If you release the mouse button, the operator is inserted on the cursors last highlighted position. Please take care that an exampleset and it's cluster model are provided on this location.

Each measure is an implemenation of well known algorithms for cluster evaluation. There is a great bunch of literature on this topic. You probably can read it.

Hi....

I will search for an article about centroid-mean distancie , Davies Boldin Distancie, and so on.

Found then, I'll out the link here...ok?

Thanks for all.
