# MLSoundClassifier.ModelParameters

Parameters that affect the process of training a sound-classifier model.

## Declaration

```swift
struct ModelParameters
```

## Overview

Overview By default, a sound-classifier training session’s transfer-learning algorithm uses the MLSoundClassifier.ModelParameters.FeatureExtractorType.audioFeaturePrint(type:revision:) feature extractor. See MLSoundClassifier.ModelParameters.FeatureExtractorType for more information.
