However, AI has since splintered into many different subfields, such as machine learning, vision, navigation, reasoning, planning, and natural language processing. the training set is large, stochastic gradient descent is often preferred over The course will also discuss recent applications of machine learning, such as to robotic control, data mining, autonomous navigation, bioinformatics, speech recognition, and text and web data processing. step used Equation (5) withAT = , B= BT =XTX, andC =I, and specifically why might the least-squares cost function J, be a reasonable according to a Gaussian distribution (also called a Normal distribution) with, Hence, maximizing() gives the same answer as minimizing.
