"Filtering based on frequency for numeric value, please have a look"

Anuj_Gupta

Hi Folks,
            I want to filter attributes based on frequency for numeric value. Can anybody suggest me some operator which will filter numeric attributes based on frequency?

I tried with operator "Remove Useless Attributes", that perfectly works for nominal attributes based on frequency but for numerical attribute, it works based on standard deviation instead o frequency.

So I am looking for some operator which will filter numerical attributes based on frequency.

Any suggestions in this regard will be appreciated.

Thanks for your timing.

Hi,

well, actually it is not really useful to count all numerical values since they could be infinitesimal and not really countable. But you could easily transform the numerical attributes into ranges first (using one of the discretization operators), count the range occurences and perform the filtering of the unwanted ranges then.

Cheers,
Ingo
