Have you ever wondered why YouTube plays the music you want to listen to? Or, when you're purchasing on Amazon, there's a "recommended for you" section? Machine learning is the answer.

Machine learning applications are rapidly entering our daily lives as technology advances towards providing smart mobile-centric solutions.
