Grad X hx - y m. Grad should have the same dimensions as theta h sigmoidXtheta. If y 1.

One for y1 and one for y0.

Cost of gradient step is high use stochastic gradient descent Carlos Guestrin 2005. But as h θ x -. One for y1 and one for y0. The procedure is similar to what we did for linear regression.
