The “hello world” of neural networks

Neural networks — also known as “deep learning” — are hot!

And now iOS 10 and macOS 10.12 come with the BNNS framework, or Basic Neural Network Subroutines, that lets you put neural networks into your own apps.BNNS runs on the CPU and is heavily optimized to be as fast as possible. There is also a version of these routines that use Metal and the GPU (part of the Metal Performance Shaders framework).

In this post I’ll show you how to get a really basic neural network up and running with BNNS.
