Struct GroupedSplit 

pub struct GroupedSplit {
    pub rows: RowSplit,
    pub train_groups: Arc<[i64]>,
    pub test_groups: Arc<[i64]>,
    pub seed: u64,
}

Grouped split: entire groups assigned to train or test (no leakage).

Fields

rows: RowSplit

Row partition.

train_groups: Arc<[i64]>

Group ids assigned to train.

test_groups: Arc<[i64]>

Group ids assigned to test.

seed: u64

Seed.

Implementations

impl GroupedSplit

pub fn try_new( group_ids: &[i64], test_frac: f64, seed: u64, ) -> Result<Self, DataError>

Assign whole groups by shuffling unique group ids.

Errors

Length mismatch, fewer than two groups, or invalid fraction.
