Fits a transformer to a sequence of examples.

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

## Parameters

`input`

A sequence of examples used for fitting the transformer.

`eventHandler`

An event handler.

## Return Value

The fitted transformer.
