Is the minimum classification error plot equivalent to a learning curve in Classification Learner app

Hi,

I'm trying to evaluate different classification models for a multiclass classification problem. One of the very basic tool to do such an evaluation is to plot the so-called learning curve which provides the error scores on both the validation sets and the training sets.

The minimum classification error plot is not available for most models, saying that the model is not optimized.

Is there another way to get the learning curves ?

Thank you in advance !
