In the sample code below, I'd like to log the optimisation of a model, e.g. finding the best value for K of a KNN model.
to be to plot the performance of the model during optimisation phase. for a number of parameters.

    You cane use the log operator as shown below, then you get the results as a log example set and can plot them

    Be careful with your Remember/Recall construct! Your construct is saving the last iteration and not the best model. This might be not the thing you want to do. You can simply use the model port of Optimize to get the best model.

    And why do you need the delay?

    martin, cheers for the response.
    cheers for the heads up on the remember / recall; I had missed picking up the port from the optimise as apposed to the validation.

    I thought I needed the delay to allow the optimise to complete. when I reorder the process execution it works fine without it.

    thanks for the help.
