"(solved) Clustering and classify unlabelled dataset"

blueearth

Hi all.
I have an example set without any special attributes ...is it possible to run unsupervised clustering or classification on it in order to cluster or classify these data?
for example i have set of regular attributes and i want a model to cluster or classify them with regards to regular attributes...is there any operator or processes for this purpose
Thank you.

Hello

Yes indeed - all the clustering algorithms can do this.

Here's an example using k-means. For fun, it also joins the cluster result back to the original and maps clusters to labels to come up with a classification performance.

Hi thank you so much
but unfortunately i didn't get it
here we have spacial attributes such as label and id in that example but what i have is an example set with out any special attributes and id its all just regular attributes and i want to know is it possible to cluster or classify them according to regular attributes?
thanks alot

Hello

Select the Clustering operator and set a breakpoint before it executes and one after.

If you run the process you will see that the input to the operator is an example set consisting of 4 regular attributes whilst the output has an id and a cluster attribute added.
