# MLSoundClassifier.ModelParameters.ModelAlgorithmType

The algorithm options to train a sound classifier.

```
enum ModelAlgorithmType
```

## Topics

### Designating an algorithm

[`case transferLearning(featureExtractor: MLSoundClassifier.ModelParameters.FeatureExtractorType, classifier: MLSoundClassifier.ModelParameters.ClassifierType)`](/documentation/CreateML/MLSoundClassifier/ModelParameters-swift.struct/ModelAlgorithmType/transferLearning(featureExtractor:classifier:))

An algorithm that leverages the knowledge of a general-purpose model built into the operating system.

[`enum FeatureExtractorType`](/documentation/CreateML/MLSoundClassifier/ModelParameters-swift.struct/FeatureExtractorType)

The feature-extractor options for a sound-classifier training algorithm.

[`enum ClassifierType`](/documentation/CreateML/MLSoundClassifier/ModelParameters-swift.struct/ClassifierType)

The classifier options for a sound classifier training algorithm.

### Describing an algorithm

[`var description: String`](/documentation/CreateML/MLSoundClassifier/ModelParameters-swift.struct/ModelAlgorithmType/description)

A text representation of the training algorithm.
