# validation

Validation data.

## Declaration

```swift
var validation: MLSupportVectorClassifier.ModelParameters.ValidationData { get set }
```

## Discussion

Discussion The default is .split(strategy: .automatic), which automatically generates the validation dataset from 0% to 10% of the training dataset.
