Understand how gradient boosting does gradient descent in function space to minimize any differentiable loss function in the service of creating a good model.

Get down with the intuition for gradient descent via a fresh analogy, develop the mathematical formulation of the algorithm, and implement it from scratch to train a linear regression model.
