How 3 developers used Core ML to run AI models on an iPhone

Apple's first iPhone launched in 2007, decades after the concept of machine learning -- a subset of artificial intelligence (AI) that employs mathematical techniques that "teach" software to make sense of complicated datasets -- rose to prominence. But it was only recently that the two collided. Apple launched Core ML, a framework designed to speed up machine learning tasks, alongside iOS 11 in May 2017. The Cupertino company shipped its first chip purpose-built for AI, the A11 Bionic, in last year's iPhone X. And at the 2018 Worldwide Developers Conference (WWDC), it took the wraps off Core ML 2, a new and improved version of Core ML; and Create ML, a GPU-accelerated tool for native AI model training on Macs.
