Struct StratifiedGrouped 

pub struct StratifiedGrouped {
    pub k: usize,
}

The two constraints at once, which is where they stop composing cleanly: with the groups kept whole, exact strata are usually not reachable at all. So this is greedy and approximate, and says so — sklearn’s StratifiedGroupKFold is greedy for the same reason, because the exact problem is a bin packing.

Needs both by_class and in_groups.

Fields

k: usize

How many folds.

Implementations

impl StratifiedGrouped

pub fn folds(&self, samples: &Samples) -> Result<Vec<Fold>, PartitionError>

The folds, in order.

Trait Implementations

impl Clone for StratifiedGrouped

fn clone(&self) -> StratifiedGrouped

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StratifiedGrouped

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for StratifiedGrouped

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<StratifiedGrouped> for Partition

fn from(cut: StratifiedGrouped) -> Self

Converts to this type from the input type.

impl Hash for StratifiedGrouped

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StratifiedGrouped

fn eq(&self, other: &StratifiedGrouped) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
