Boss level: gradient-descent playground
Splash Park wants a sign at the Big Drop that says how long the wait is. You have twelve days of measurements and a two-setting model. You'll train it by gradient descent, find the learning rate where training blows up, discover why, fix it with feature scaling, and then build the whole training loop in Python and check it against the exact answer. Every idea from this course meets here.
