iOS Machine Learning Tutorial: Getting Started

In this iOS machine learning tutorial, you’ll learn how to get started with developing machine learning models on iOS. You’ll see how to use Core ML and Create ML to develop and train your own custom models, and how to integrate them into your iOS apps.

Introduction

In this iOS machine learning tutorial, you’ll learn how to get started with Core ML and build a simple hand-written digit recognition app. With Core ML, you can use trained machine learning models to perform predictions on live data. This is a great way to add intelligence to your apps without having to write any complex algorithms yourself.

To follow along with this tutorial, you’ll need Xcode 9 and Swift 4. You’ll also need a basic understanding of machine learning concepts. If you’re not familiar with these topics, I recommend checking out my earlier tutorial on the subject: What is Machine Learning?

Once you’re ready to get started, download the project files at the top of this page and let’s dive in!

What is Machine Learning?

Machine learning is a type of artificial intelligence (AI) that allows software to get better at performing a task with data over time. With machine learning, your software can learn from experience without being explicitly programmed to do so. Machine learning is a core component of many AI applications, including image recognition, object detection, and natural language processing (NLP).

What is iOS Machine Learning?

Machine learning is a type of artificial intelligence (AI) that provides computers with the ability to learn without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it learn for themselves.

The process of machine learning is similar to that of data mining. Both systems search through data to look for patterns. However, machine learning goes a step further and also uses these patterns to make predictions about new data. Machine learning is often used to build predictive models, such as regression or classification models.

iOS machine learning allows developers to use these same techniques in their apps. With iOS machine learning, developers can harness the power of predictive modeling to build smarter apps that can predict what users want and need.

In this tutorial, you will learn the basics of iOS machine learning. You will start by building a simple app that uses a pre-trained machine learning model to make predictions about photos. You will then learn how to train your own custom machine learning models and use them in your apps. By the end of this tutorial, you will have the skills you need to begin integrating machine learning into your own iOS apps.

Setting up your iOS Machine Learning environment

In this iOS machine learning tutorial, you’re going to learn how to set up your environment for iOS machine learning. Machine learning on iOS requires a few tools, which are all freely available and installed via Homebrew.

Before we get started, make sure you have the latest version of Xcode installed. You can get it from the App Store or the Apple Developer website.

Next, install Homebrew. Homebrew is a package manager for macOS that makes it easy to install command line tools and libraries. To install Homebrew, open a terminal and enter the following command:

/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)”

Once Homebrew is installed, run the following commands to install the required tools and libraries:

brew install python3
pip3 install numpy scipy matplotlib jupyter ipython seaborn pandas

Getting started with iOS Machine Learning

Machine learning is a field of artificial intelligence that enables computers to learn from data, identify patterns and make predictions. It’s being used more and more to power everything from search algorithms to self-driving cars. And now, with the new Core ML framework in iOS 11, it’s easy for developers to put machine learning models into their apps.

In this iOS machine learning tutorial, you’ll learn how to use the Core ML framework to integrate a pre-trained machine learning model into an iPhone app. You’ll also learn how to retrain that model using new data gathered by the app. By the end of this tutorial, you will have built a simple app that can identify pictures of furniture and give you information about that piece of furniture.

Preprocessing your data

In machine learning, preprocessing refers to the various steps taken to prepare data for use in a machine learning model. This typically includes tasks such as cleaning data, scaling features, and transforming data into a format that is suitable for training a machine learning model.

Preprocessing data is an important step in any machine learning project, and it is especially important when working with images. In this tutorial, you will learn how to preprocess image data for use in a convolutional neural network (CNN). You will also learn how to perform data augmentation, which is a technique used to improve the performance of CNNs by increasing the amount of training data.

Data augmentation is a technique that is commonly used in computer vision, and it is especially useful for image classification tasks. Data augmentation takes existing images and applies random transformations to them, such as cropping, flipping, or rotating. The goal of data augmentation is to create new images that are similar to the existing images, but that are different enough that they can be used to improve the performance of a machine learning model.

Training your Machine Learning model

In order to get started with training your own machine learning models, there are a few things you’ll need:
-A computer running macOS (10.13 or higher) and Xcode 9.0 or higher
-An iOS device running iOS 11 or higher
-The latest versions of TensorFlow, Keras, and other Python libraries installed on your computer

Evaluating your Machine Learning model

After completing this tutorial, you will know how to:
-Evaluate your machine learning model on iOS.
-Use Core ML to integrate a machine learning model into your app.
– utilize Model Optimization to decrease the size of your Core ML model.

Core ML is a framework that allows you to integrate machine learning models into your app. Model evaluation is the process of assessing how well your machine learning model performs on data. In this tutorial, you will learn how to evaluate your machine learning model on iOS using Core ML.

You will start by loading the Iris dataset into a pandas DataFrame. You will then train a logistic regression model on the dataset. Next, you will convert the trained model to Core ML format and integrate it into your app. Finally, you will evaluate the performance of the model on unseen data.

Tuning your Machine Learning model

Welcome to the second part of our iOS Machine Learning tutorial! In the first part, we showed you how to get started with Core ML and build a simple image recognition app.

In this part, we’re going to take a closer look at how to fine-tune your machine learning model to get the best results. We’ll also be covering how to use some of the more advanced features of Core ML, such as pre- and post-processing.

So let’s get started!
