An anonymous reader writes: In November, Google open sourced TensorFlow, its machine learning platform. Now, the company is following up by teaching people how to use it. They've launched a free course at Udacity that "provides you with all the basic tools and vocabulary to get started with deep learning, and walks you through how to use it to address some of the most common machine learning problems." A series of lectures explains how to set up your data, build training models, and extend those models. It also touches on image recognition and how to use recurrent neural networks. The signup page notes that this is considered an intermediate-to-advanced level course, so you'll probably need some basic machine learning knowledge to get the most out of it.
