Apple's Core ML 2 is 30% faster, cuts AI model sizes by up to 75%

Apple announced Core ML 2, a new version of its suite of machine learning apps for iOS devices, at the Worldwide Developers Conference (WWDC) 2018 in San Jose, California today. Core ML 2 is 30 percent faster, Apple says, thanks to a technique called batch prediction. Furthermore, Apple said the toolkit will let developers shrink the size of trained machine learning models by up to 75 percent through quantization. Apple also announced Create ML, a new GPU-accelerated tool for native AI model training on Macs. The tool supports vision and natural language, as well as custom data.
