Answer: Leave-one-out cross-validation, bootstrap sampling, and repeated random sub-sampling.
Model validation in AutoML involves assessing the model's performance on unseen data to ensure it generalizes well to new instances. Cross-validation is a critical technique for this, as it partitions the data into multiple folds and trains the model on different subsets, reducing the risk of overfitting. Examples of cross-validation techniques used in AutoML include leave-one-out cross-validation, where each data point is used as a validation set once, bootstrap sampling, which involves resampling with replacement, and repeated random sub-sampling, which randomly splits the data into training and validation sets multiple times.
