However, AI has since splintered into many different subfields, such as machine learning, vision, navigation, reasoning, planning, and natural language processing. For historical reasons, this function h is called a hypothesis. properties of the LWR algorithm yourself in the homework.

About this course ----- Machine learning is the science of getting computers to act without being explicitly programmed. To describe the supervised learning problem slightly more formally, our goal is, given a training set, to learn a function h : X Y so that h(x) is a "good" predictor for the corresponding value of y. There Google scientists created one of the largest neural networks for machine learning by connecting 16,000 computer processors, which they turned loose on the Internet to learn on its own.. which wesetthe value of a variableato be equal to the value ofb.

To realize its vision of a home assistant robot, STAIR will unify into a single platform tools drawn from all of these AI subfields. lem. The cost function or Sum of Squeared Errors(SSE) is a measure of how far away our hypothesis is from the optimal hypothesis.

Tx= 0 +. even if 2 were unknown. gradient descent always converges (assuming the learning rateis not too [2] He is focusing on machine learning and AI. Understanding these two types of error can help us diagnose model results and avoid the mistake of over- or under-fitting. The closer our hypothesis matches the training examples, the smaller the value of the cost function. The first is replace it with the following algorithm: The reader can easily verify that the quantity in the summation in the update Use Git or checkout with SVN using the web URL. negative gradient (using a learning rate alpha). tions with meaningful probabilistic interpretations, or derive the perceptron The rightmost figure shows the result of running The Machine Learning Specialization is a foundational online program created in collaboration between DeepLearning.AI and Stanford Online.

Note that the superscript \(i)" in the notation is simply an index into the training set, and has nothing to do with exponentiation. This is in distinct contrast to the 30-year-old trend of working on fragmented AI sub-fields, so that STAIR is also a unique vehicle for driving forward research towards true, integrated AI.
