Trait linfa::dataset::AsTargets

pub trait AsTargets {
    type Elem;
    fn as_multi_targets(&self) -> ArrayView2<'_, Self::Elem>;

    fn try_single_target(&self) -> Result<ArrayView1<'_, Self::Elem>> { ... }
}

Return a reference to single or multiple target variables

Associated Types

type Elem

Required methods

fn as_multi_targets(&self) -> ArrayView2<'_, Self::Elem>

Returns a view on targets as two-dimensional array

Provided methods

fn try_single_target(&self) -> Result<ArrayView1<'_, Self::Elem>>

Convert to single target, fails for more than one target

Returns

May return a single target with the same label type, but returns an Error::MultipleTargets in case that there are more than a single target.
