Gridsearchcv learning curve
WebJan 28, 2024 · I am trying to train a MLPClassifier with the MNIST dataset and then run a GridSearchCV, Validation Curve and Learning Curve on it. Every time any cross-validation starts (either with GridSearchCV, learning_curve, or validation_curve), Python crashes unexpectedly. Steps/Code to Reproduce WebA plot of the training/validation score with respect to the size of the training set is known as a learning curve. The general behavior we would expect from a learning curve is this: A model of a given complexity will overfit a small dataset: this means the training score will be relatively high, while the validation score will be relatively low.
