Struct TimeSeries 

pub struct TimeSeries {
    pub k: usize,
    pub gap: usize,
}

The one scheme that is deliberately not a partition: the first block has nothing before it to learn from, so it only ever trains and is never held out. Every other scheme here holds out each sample exactly once.

gap drops that many samples between the two sides, which is what purged and embargoed cross-validation are — a parameter, not a scheme. It uses neither the classes nor the groups, and unlike the rest k = 1 is meaningful: a plain holdout of the tail.

Fields

k: usize

How many splits.

gap: usize

How many samples to drop between training and test.

Implementations

impl TimeSeries

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

The folds, oldest first.

Trait Implementations

impl Clone for TimeSeries

fn clone(&self) -> TimeSeries

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeSeries

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

Formats the value using the given formatter.

impl Display for TimeSeries

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

Formats the value using the given formatter.

impl From<TimeSeries> for Partition

fn from(cut: TimeSeries) -> Self

Converts to this type from the input type.

impl Hash for TimeSeries

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 TimeSeries

fn eq(&self, other: &TimeSeries) -> 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.
