# MLTextClassifier.ModelParameters

Parameters that specify model training parameters and validation data.

```
struct ModelParameters
```

## Topics

### Creating parameters

[`init(validation:algorithm:language:)`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/init(validation:algorithm:language:))

Creates model parameters for a text classifier with the specified validation data, algorithm, and language.

  <doc://com.apple.documentation/documentation/NaturalLanguage/NLLanguage>

[`MLTextClassifier.ModelAlgorithmType`](/documentation/CreateML/MLTextClassifier/ModelAlgorithmType)

The type of algorithm that a text classifier uses.

[`MLTextClassifier.ModelParameters.ValidationData`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/ValidationData-swift.enum)

The validation data that a text classifier uses.

### Accessing parameters

[`algorithm`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/algorithm)

The parameter’s algorithm setting.

[`language`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/language)

The parameter’s language setting.

[`validation`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/validation)

The validation dataset.

[`maxIterations`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/maxIterations)

The maximum number of training iterations.

### Describing parameters

[`description`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/description)

A text representation of the model parameters.

[`debugDescription`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/debugDescription)

A text representation of the model parameters that’s suitable for output during debugging.

[`playgroundDescription`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/playgroundDescription)

A description of the model parameters in a playground.

### Deprecated

[`init(validationData:algorithm:language:)`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/init(validationData:algorithm:language:))

Creates parameters for a text classifier with validation data in a
set of labeled directories.

[`init(validationData:algorithm:language:textColumnValidationData:labelColumnValidationData:)`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/init(validationData:algorithm:language:textColumnValidationData:labelColumnValidationData:))

Creates parameters for a text classifier with validation data in a
data table.

[`validationData`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/validationData-swift.property)

The validation data.

[`textColumnValidationData`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/textColumnValidationData)

The name of the text column in the validation data table.

[`labelColumnValidationData`](/documentation/CreateML/MLTextClassifier/ModelParameters-swift.struct/labelColumnValidationData)

The name of the label column in the validation data table.
