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.

The following notes represent a complete, stand alone interpretation of Stanford's machine learning course presented by Professor Andrew Ng and originally posted on the ml-class.org website during the fall 2011 semester. Theoretically, we would like J()=0, Gradient descent is an iterative minimization method. All Rights Reserved.

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.
