# MLTextClassifier.ModelAlgorithmType

The type of algorithm that a text classifier uses.

## Declaration

```swift
enum ModelAlgorithmType
```

## Mentioned in

Creating a text classifier model Improving Your Model’s Accuracy

## Overview

Overview Typically, maxEnt is the fastest training algorithm. If the text classifier’s performance isn’t good enough, consider the transferLearning algorithm.
