Validation Curve

The validation curve plots the influence of a single hyperparameter on the train and validation set. By looking at the curve, we can determine the overfitting, underfitting and just-right conditions of the model for the specified values of the given hyperparameter. When there are multiple hyperparameters to tune at once, the validation curve cannot be used. Instated, you can use grid search or random search.
