We’ve already introduced models, parameters, and hyperparameters in Section 22.214.171.124. I’m about to bring them up again for two reasons. First, I want you to see a concrete analogy between (1) how we write simple Python functions in different ways by varying their code and arguments and (2) how learning models use parameters and hyperparameters. Second, we’ll turn our attention towards choosing good hyperparameters. When we
fit a model, we are choosing good parameters. We need some sort of well-defined process to choose good ...
