Trait Implementations

impl Approximator<Projection> for PairFunction

type Value = (f64, f64)

fn n_outputs(&self) -> usize

fn evaluate(&self, p: &Projection) -> EvaluationResult<(f64, f64)>

Evaluate the function and return its value.

fn update(&mut self, p: &Projection, errors: (f64, f64)) -> UpdateResult<()>

Update the approximator’s estimate for the given input.

fn adapt(
    &mut self,
    new_features: &HashMap<IndexT, IndexSet>
) -> AdaptResult<usize>

Adapt the approximator in light of newly discovered features.

impl Clone for PairFunction

fn clone(&self) -> PairFunction

Returns a copy of the value.

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