Class

MLImageClassifierBuilder

An Xcode playground UI that you use to train a model to classify images.

Overview

An image classifier is a machine learning model that takes an image as its input and makes a prediction about what the image represents. Use an image classifier builder in an Xcode playground with a macOS target to train an image classifier to make predictions.

When you create a builder, you show it in a live view:

import CreateMLUI

let builder = MLImageClassifierBuilder()
builder.showInLiveView()

After that, you interact with the builder entirely through the UI of the live view that appears in Xcode’s assistant editor. Use the configuration options that the builder gives you to control training parameters like the number of iterations and augmentation settings. Begin training the model by dragging your training data into the classifier. After training finishes, you also use the UI to test your model, and then save it to a file for use in a Core ML app.
