A linear regression model y = β X + u can be solved in one "round" by using ( X ′ X) − 1 X ′ y = β ^. It can also be solved using gradient descent but there is no need to adjust something like a learning rate or the number of epochs since the solver (usually) converges without much trouble. Here is a minimal example in R:
