Classical models built from the math you already know
By now four separate ways to predict a number from an input exist: a straight line, a bent polynomial, a vote among nearby neighbours, and a staircase of splits. Each comes from a completely different idea about how the world works. Put them on the exact same dataset, though, and they are all answering one question: given this x, what should the prediction for y be?
