Hi,

first of all let me state that modern keyboards with the "dot" and "comma" keys are available in your local computer store. Using such a keyboard can greatly improve the readability of your texts

Concerning your question: I don't fully understand what you mean by "put 2 classification operators one follow each other". Can you be a bit more specific?

All the best,
Marius

I mean that I want to use 2 classification operators instead of 1 for more accurcy of the classification eg: use KNN operator then put NB operator

do you now understand or no

Hi

if you mean putting them back to back i.e. in series, then why not. You can do it in RM.

k-nn will output K clusters and the subsequent clustering may produce new clusters out of the K clusters (centroids or whatever).
