To make gradient descent converge, we must slowly decrease α over time.

Gradient descent is guaranteed to find the global minimum for any function ).

Gradient descent can converge even if α cannot be too large, or else it may fail to converge.)

For the specific choice of cost function ) used in linear regression, there are no local optima (other than the global optimum).
