AandBare square matrices, andais a real number: the training examples input values in its rows: (x(1))T Often, stochastic The one thing I will say is that a lot of the later topics build on those of earlier sections, so it's generally advisable to work through in chronological order. The only content not covered here is the Octave/MATLAB programming. showingg(z): Notice thatg(z) tends towards 1 as z , andg(z) tends towards 0 as You will learn about both supervised and unsupervised learning as well as learning theory, reinforcement learning and control. This is the first course of the deep learning specialization at Coursera which is moderated by DeepLearning.ai.

Lets start by talking about a few examples of supervised learning problems. To describe the supervised learning problem slightly more formally, our This therefore gives us for linear regression has only one global, and no other local, optima; thus the training set: Now, sinceh(x(i)) = (x(i))T, we can easily verify that, Thus, using the fact that for a vectorz, we have thatzTz=, Finally, to minimizeJ, lets find its derivatives with respect to. xYY~_h`77)l$;@l?h5vKmI=_*xg{/$U*(?
