Knowledge remains power and Google wants to spread the wealth.

On Thursday, the company launched a free, three-month course — open to all its users — to explain machine learning in depth.

Available on the education website Udacity, the deep-learning course could be completed over the three-month period, as long as users do six hours of work per week. Vincent Vanhoucke, principal scientist at Google and technical lead of the company's Brain team, oversaw the development of the machine-learning course.

"Machine learning is one of the fastest-growing and most exciting fields out there, and deep learning represents its true bleeding edge," a blog post on Udacity reads. "In this course, you'll develop a clear understanding of the motivation for deep learning, and design intelligent systems that learn from complex and/or large-scale datasets."

It adds: "We'll show you how to train and optimize basic neural networks, convolutional neural networks, and long short term memory networks. Complete learning systems in TensorFlow will be introduced via projects and assignments. You will learn to solve new classes of problems that were once thought prohibitively challenging, and come to better appreciate the complex nature of human intelligence as you solve these same problems effortlessly using deep learning methods."

Google has been using deep learning techniques to make its website run for quite some time. Consider this, its way of giving back.

The course will take users through four different lectures, increasing their knowledge with each component, ranging from setting up your data and experimental protocol to making simple models deeper in scale, image recognition and exploring models for text and sequences.
