What is Bootstrapping, and how does it differ from Cross-Validation?
- A method for resampling data with replacement
- A technique for training ensemble models
- A technique to reduce bias
- A type of Cross-Validation
Bootstrapping is a method for resampling data with replacement, used to estimate statistics about a population from a sample. It differs from Cross-Validation, where data is split without replacement to validate the model. Bootstrapping is more about estimating the properties of an estimator, while Cross-Validation assesses the model's performance.
