Understanding these two types of error can help us diagnose model results and avoid the mistake of over- or under-fitting. They're identical bar the compression method. /FormType 1 The cost function or Sum of Squeared Errors(SSE) is a measure of how far away our hypothesis is from the optimal hypothesis.

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. 1416 232 The offical notes of Andrew Ng Machine Learning in Stanford University. 0 and 1. What You Need to Succeed The only content not covered here is the Octave/MATLAB programming. (In general, when designing a learning problem, it will be up to you to decide what features to choose, so if you are out in Portland gathering housing data, you might also decide to include other features such as .
