What are the best validation methods for deep learning models?

Some popular validation methods include k-fold cross-validation, holdout validation, and stratified sampling.

Can you explain k-fold cross-validation?

Sure! K-fold cross-validation involves splitting the dataset into k subsets. The model is trained on k-1 subsets and validated on the remaining subset. This process is repeated k times.

What are the advantages of using k-fold cross-validation?

It provides a more reliable estimate of model performance, reduces overfitting, and makes better use of the data.

Are there any disadvantages to k-fold cross-validation?

Yes, it can be computationally expensive, especially with large datasets, and may not be suitable for time-series data.
