Struct ShuffleSplit 

pub struct ShuffleSplit { /* private fields */ }

Shuffle Split cross-validator

Generates random train/test splits independent of the number of iterations

Implementations

impl ShuffleSplit

pub fn new(n_splits: usize) -> Self

Create a new ShuffleSplit cross-validator

pub fn test_size(self, size: f64) -> Self

Set the test size as a proportion (0.0 to 1.0) of the dataset

pub fn train_size(self, size: f64) -> Self

Set the train size as a proportion (0.0 to 1.0) of the dataset

pub fn random_state(self, seed: u64) -> Self

Set the random state for reproducible results
