You will learn about both supervised and unsupervised learning as well as learning theory, reinforcement learning and control. Topics include: supervised learning (generative/discriminative learning, parametric/non-parametric learning, neural networks, support vector machines); unsupervised learning (clustering, discrete-valued, and use our old linear regression algorithm to try to predict Newtons It upended transportation, manufacturing, agriculture, health care. This beginner-friendly program will teach you the fundamentals of machine learning and how to use these techniques to build real-world AI applications.
