It's not yet CoreML2, but I've been testing how Apple has integrated Machine Learning into its toolbox.

I just saw an article for this: https://www.affectiva.com over at Slashdot (https://developers.slashdot.org/story/17/05/21/2137208/how-ai-can-infer-...).

Of course, using a massive database with humans providing the context, machines can learn, but can not understand.

Thus, they can't explain their decisions, or help emotional cognition, just recognition.
