Without a doubt my beloved Python is the Lingua Franca for machine learning these days. Tons of create tools by Google, Facebook and other big players make it easy to learn about machine learning. All offer a great Python API. At Amazon you find 200+ books teaching you stuff about machine learning using Python. A lot of material to choose from. And from my point of view, also a lot of material to fail with. Let me recommend two books I find particularly helpful, when you want to learn something about these fascinating fields and start to dive into one of the hottest topics in tech at the moment.
