What are the benefits of k-fold validation in machine learning?
K-fold validation helps in assessing the model's performance more reliably by using different subsets of data for training and testing.
How does it improve model accuracy?
By averaging the results from multiple folds, it reduces the variance and provides a better estimate of model performance.
Are there any downsides to using k-fold validation?
Yes, it can be computationally expensive, especially with large datasets, and may lead to longer training times.
What is the typical value for k?
Common values for k are 5 or 10, but it can vary depending on the dataset size and specific use case.
