Perceptrons in Swift – BPXL Craft – Medium

With the new machine learning (ML) frameworks introduced during WWDC 2017, iOS/macOS/tvOS programmers now have the tools to simplify the implementation of powerful ML algorithms within their apps. A simple hand-waving explanation of how neural networks work will get you surprisingly far, but a little more knowledge and experimentation will help remove some of the mystery behind how they actually work. This first article will implement a simple perceptron network using a Swift Playground to show how a basic network works. Perceptrons were invented in the late 1950s and implemented directly in hardware to explore machine vision. Perceptrons represent a simplified model of a biological neuron.
