Trait linfa::dataset::FromTargetArray

pub trait FromTargetArray<'a>: AsTargets {

    fn new_targets(targets: Array<Self::Elem, Self::Ix>) -> Self::Owned;

Helper trait to construct counted labels

This is implemented for objects which can act as targets and created from a target matrix. For targets represented as ndarray matrix this is identity, for counted labels, i.e. TargetsWithLabels, it creates the corresponding wrapper struct.

Required Associated Types

type Owned

type View

Required Methods

fn new_targets(targets: Array<Self::Elem, Self::Ix>) -> Self::Owned

Create self object from new target array

fn new_targets_view(targets: ArrayView<'a, Self::Elem, Self::Ix>) -> Self::View

Implementations on Foreign Types

impl<'a, L: Clone + 'a, S: Data<Elem = L>, I: TargetDim> FromTargetArray<'a> for ArrayBase<S, I>

fn new_targets(targets: Array<L, I>) -> Self::Owned

Returns an owned representation of the target array

fn new_targets_view(targets: ArrayView<'a, L, I>) -> Self::View

Returns a reference to the target array

type Owned = ArrayBase<OwnedRepr<L>, I>

type View = ArrayBase<ViewRepr<&'a L>, I>
