Machine Learning is "the science of getting computers to act without being explicitly programmed." Today, machine learning is used in healthcare, data mining, and transportation (most famously in self driving cars), to name just a few areas where this technology is invoked. This 11-week long online course, developed by Stanford University and powered by Coursera, teaches learners about machine learning, a field that blends mathematics, neuroscience, and computer science. While users need to pay a fee to take the entire course for credit, there is also the option of taking the course for free without credit. The course includes instructional videos, quizzes, and assignments. Prior to taking the course, visitors will want to take a short readiness quiz to ensure that they have the right math background to participate in the course.
