Is there a way to count distance matrix using dynamic time warping between whole data sets? Meening i have 23 data sets with the same atributes and i want to count distance matrix 23x23.

 

I am new to rapidminer and got this thing assigned to me at school and i am really strugling to find a guide or help for how to do this.

 

Thanks in advance for every advice.

    Hi Lourman,

     

    the operator is called cross distance. To put the result into a matrix format you can use pivot.

    But cross distance give me the distance between each row of the request and testing set. But i need distance between the request set and testing set as a whole, not by rows. Is it right to count this value as an average of the distances between rows?
