Struct GroupShuffleSplit 

pub struct GroupShuffleSplit { /* private fields */ }

Group Shuffle Split cross-validator

Generates random train/test splits that respect group constraints. Ensures that the same group is not in both training and test sets.

Implementations

impl GroupShuffleSplit

pub fn new(n_splits: usize) -> Self

Create a new GroupShuffleSplit cross-validator

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

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

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

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

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

Set the random state for reproducible results

pub fn split_with_groups( &self, n_samples: usize, groups: &Array1<i32>, ) -> Vec<(Vec<usize>, Vec<usize>)>

Split data based on groups
