## Declaration

```swift
func update<InputSequence, FeatureSequence>(_ transformer: inout UpdatableSupervisedEstimatorToTemporalAdaptor<Base>.Transformer, with input: InputSequence, eventHandler: EventHandler? = nil) async throws where InputSequence : Sequence, FeatureSequence : TemporalSequence, InputSequence.Element == AnnotatedFeature<FeatureSequence, Base.Annotation>, FeatureSequence.Feature == Base.Transformer.Input
```

## Parameters

- `transformer`: A transformer to update.
- `input`: A sequence of examples.
- `eventHandler`: An event handler.
