The figure shows gradient descent on a convex cost function. The parameter θ\thetaθ starts near the bottom of the curve, but the updates repeatedly jump from one side of the valley to the other, moving far away from the minimum. What is the best interpretation of this behavior?

A student trains a linear regression model using gradient descent. One feature is house size measured from 500 to 5,000 square feet, while another feature is number of bedrooms measured from 1 to 6. The student does not scale the features, and gradient descent takes a long time to converge. Why is feature scaling important in this situation?
