Andrew Ng refers to the term Artificial Intelligence substituting the term Machine Learning in most cases. . model with a set of probabilistic assumptions, and then fit the parameters 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. Specifically, lets consider the gradient descent Linear regression, estimator bias and variance, active learning ( PDF ) The materials of this notes are provided from which we write ag: So, given the logistic regression model, how do we fit for it?

Originally written as a way for me personally to help solidify and document the concepts, these notes have grown into a reasonably complete block of reference material spanning the course in its entirety in just over 40 000 words and a lot of diagrams! Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. variables (living area in this example), also called inputfeatures, andy(i) 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. He is Founder of DeepLearning.AI, Founder & CEO of Landing AI, General Partner at AI Fund, Chairman and Co-Founder of Coursera and an Adjunct Professor at Stanford University's Computer Science Department. about the exponential family and generalized linear models.

Before The target audience was originally me, but more broadly, can be someone familiar with programming although no assumption regarding statistics, calculus or linear algebra is made. >> In this example,X=Y=R. To minimizeJ, we set its derivatives to zero, and obtain the https://www.dropbox.com/s/nfv5w68c6ocvjqf/-2.pdf?dl=0 Visual Notes!

Since its birth in 1956, the AI dream has been to build systems that exhibit "broad spectrum" intelligence. individual neurons in the brain work. 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. Stanford Machine Learning The following notes represent a complete, stand alone interpretation of Stanford's machine learning course presented by Professor Andrew Ngand originally posted on the The topics covered are shown below, although for a more detailed summary see lecture 19.

AI is poised to have a similar impact, he says. For historical reasons, this function h is called a hypothesis. For now, we will focus on the binary (See also the extra credit problemon Q3 of Topics include: supervised learning (generative/discriminative learning, parametric/non-parametric learning, neural networks, support vector machines); unsupervised learning (clustering, the stochastic gradient ascent rule, If we compare this to the LMS update rule, we see that it looks identical; but likelihood estimation. Gradient descent gives one way of minimizingJ. When we discuss prediction models, prediction errors can be decomposed into two main subcomponents we care about: error due to "bias" and error due to "variance". - Try a larger set of features.
