Machine learning

Core ML adds new instruments and performance reports in Xcode, so you can analyze your ML-powered features. Optimize your Core ML integration with new Float16 data types, efficient output backings, sparse weight compression, in-memory model support, and new options to restrict compute to the CPU and Neural Engine.

In the Create ML app, explore key evaluation metrics and their connections to specific examples from your test data to help identify challenging scenarios and further investments in data collection to help improve model quality. Preview your model’s predictions on live video from your iPhone camera. And use the new Create ML Components framework to define your own custom model and training pipelines by combining a rich set of ML building blocks.
