This workflow shows how to use the legacy version of the parameter optimization component. This component only works out of the box with a random forest classification which optimizes the number of trees and the max tree depth. Changing which parameters and which model is optimized requires unlinking and editing the component. You can still use this legacy component as a template, in case you want to create your own component. We recommend, however to adopt the Parameter Optimization (Table) component (kni.me/c/A_91QC387NtvJ6g8).
