Trait BaseKFold

pub trait BaseKFold {
    type Output: Iterator<Item = (Vec<usize>, Vec<usize>)>;

    // Required methods
    fn split<T: Number, X: Array2<T>>(&self, x: &X) -> Self::Output;
    fn n_splits(&self) -> usize;
}

An interface for the K-Folds cross-validator

Required Associated Types

type Output: Iterator<Item = (Vec<usize>, Vec<usize>)>

An iterator over indices that split data into training and test set.

Required Methods

fn split<T: Number, X: Array2<T>>(&self, x: &X) -> Self::Output

Return a tuple containing the the training set indices for that split and the testing set indices for that split.

fn n_splits(&self) -> usize

Returns the number of splits

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
