Function train_test_split 

pub fn train_test_split(
    n_samples: usize,
    test_size: f64,
    seed: Option<u64>,
) -> CoreResult<SplitIndices>

Split data indices into training and test sets.

Arguments

• n_samples - Total number of samples
• test_size - Fraction of data to use for testing (0.0 .. 1.0)
• seed - Optional random seed for reproducibility

Example

use scirs2_core::data_split::train_test_split;

let (train, test) = train_test_split(100, 0.2, Some(42)).expect("split failed");
assert_eq!(train.len() + test.len(), 100);
assert_eq!(test.len(), 20);
