# fitted(to:eventHandler:)

Fits a transformer to a sequence of examples.

## Declaration

```swift
func fitted<InputSequence, FeatureSequence>(to input: InputSequence, eventHandler: EventHandler? = nil) async throws -> UpdatableTemporalEstimatorToSupervisedAdaptor<Estimator, Annotation>.Transformer where InputSequence : Sequence, FeatureSequence : TemporalSequence, InputSequence.Element == AnnotatedFeature<FeatureSequence, Annotation>, FeatureSequence.Feature == Estimator.Transformer.Input
```

## Parameters

- `input`: A sequence of examples used for fitting the transformer.
- `eventHandler`: An event handler.

## Return Value

Return Value The fitted transformer.
