Advantages:
Checking Model Generalization: Cross-validation gives the idea about how the model will generalize to an unknown dataset
Checking Model Performance: Cross-validation helps to determine a more accurate estimate of model prediction performance
Disadvantages:
Higher Training Time: with cross-validation, we need to train the model on multiple training sets.
Expensive Computation: Cross-validation is computationally very expensive as we need to train on multiple training sets.
