# PreprocessingUpdatableTabularEstimator

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

## Declaration

```swift
struct PreprocessingUpdatableTabularEstimator<Preprocessor, Estimator> where Preprocessor : TabularTransformer, Estimator : UpdatableTabularEstimator
```
