adrianliaw wants to merge 1 commit into mstampfer:master from adrianliaw:master

adrianliaw commented Nov 25, 2016

Things modified:

Testing data point for applying theta produced by gradient descent and normal equation. Originally the order was wrong, square-feet should go first, then number of bedrooms.
Add feature normalization before applying the theta produced by gradient descent. As described in "Implementation Note" of section 3.1 in ex1.pdf, "We must first normalize x using the mean and standard deviation that we had previously computed from the training set."
