# StandardScaler.Transformer

A transformer that standardizes the input by removing the mean and scaling to unit variance.

## Declaration

```swift
struct Transformer
```

## Topics

### Creating a transformer

- [init(mean:standardDeviation:)](createmlcomponents/standardscaler/transformer/init(mean:standarddeviation:).md)

### Getting the properties

- [mean](createmlcomponents/standardscaler/transformer/mean.md)
- [standardDeviation](createmlcomponents/standardscaler/transformer/standarddeviation.md)

### Performing the transformation

- [applied(to:eventHandler:)](createmlcomponents/standardscaler/transformer/applied(to:eventhandler:).md)
