# PreprocessingUpdatableSupervisedEstimator

An updatable supervised estimator that composes a preprocessing transformer and an updatable supervised estimator.

## Declaration

```swift
struct PreprocessingUpdatableSupervisedEstimator<Preprocessor, Estimator> where Preprocessor : Transformer, Estimator : UpdatableSupervisedEstimator, Preprocessor.Output == Estimator.Transformer.Input
```
