Hello every body,
I use Rapidminer Desktop 8.2. My question is how to run KNN classifer multiple times with different K values and then graph the accuracies visually?
I searched the forum but didn't find any solution :-(
Hi,
have a look at Optimize Parameters (Grid). That does the trick.
Cheers,
Martin
