Estimators only print parameters that have been changed

In version 0.23 of scikit-learn, the default behavior has changed to print only the parameters that differ from their default values in estimator classes. Although this customization emphasizes the modified parameters, users can still view all parameters via the 'get_params' method. To revert to the previous behavior, users can adjust the configuration option to print all parameters. This flexibility caters to different user preferences, whether prioritizing changes or transparency in parameter settings.

Version 0.23 now prints only non-default estimator parameters.

Modified parameters 'C' and 'solver' illustrate the new print behavior.

Use 'set_config' to revert to printing all classifier parameters.
