A higher number of iterations will probably yield a better model, but also increases processing time. `alpha`, `eta` and `random_state` are so-called *hyperparameters*. They influence the model's performance, so feel free to play around with them. In the present example, we will leave the default values. Furthermore, there exist various methods for hyperparameter optimization, e.g. gridsearch or Gaussian optimization.\n",
