Alternatively, models may be created programmatically from within an app by using the CreateML class. Create ML (in the form of the CreateMLUI class) can be used from within an Xcode playground to visually create a model by writing a few lines of code, dragging and dropping training and testing datasets into the Assistant Editor, and viewing the results.

Once a complex and time-consuming task, this is now made easier through the introduction of Create ML. The first step in implementing machine learning within an iOS app is to create the model.

The full book contains 93 chapters and 760 pages of in-depth information. You are reading a sample chapter from iOS 16 App Development Essentials.īuy the full book now in eBook or Print format. Once a model is complete, it is referred to as a trained model and is ready to be used in real-world situations.

The training results can then be analyzed to check for accuracy, and the model can be improved if necessary by providing additional training data and increasing the number of iterations performed during the training phase. Once the training is complete, the model is tested by applying it to a dataset containing data not previously included during training.

The model will be built by iterating through the training dataset and learning how to categorize similar data. Similarly, a model intended to identify a particular car model from photos would need to be trained with images of the model of the car in various colors taken from multiple angles and distances. To create a model that can detect happy or sad sentiments expressed in text messages, for example, the model would need to be trained with a dataset containing both types of messages, with each message labeled to indicate whether the message is happy or sad. Machine learning begins with the gathering of datasets to be used to train and create a learning model. Machine learning is a large and complex technology area, so the goal of this and subsequent chapters is to provide an overview of the basics of this topic to get up to speed quickly and provide a knowledge basis on which to build more advanced machine learning skills. Machine learning is used in many fields and industries to perform tasks such as identifying spam emails, detecting people and objects in images, fraud detection, and financial trading systems, for example.Īpple first introduced machine learning capabilities for iOS and macOS in 2017 with the introduction of the Core ML framework and has continued to add improvements in iOS 16 with the release of Create ML.

It involves using data analysis to teach software to perform tasks without specifically being programmed. Machine learning is one of the key components of artificial intelligence.
