It is important to note that the estimator has two kinds of parameters:

  • Estimator parameters: All the parameters of an estimator can be set when it is instantiated or by modifying the corresponding attribute. Some of these estimator parameters correspond to the ML model hyperparameters. We will talk about model hyperparameters more later.
  • Estimated parameters: When data is fitted with an estimator, parameters are estimated from the data at hand. All the estimated parameters ...
