... scikit dummy.

You need to properly benchmark your models and it can be easy to forget to do this step. That is why we wanted to demonstrate the dummy module of scikit-learn. It is an underappreciated part of the library that is very useful to start with.


Let's run a dummy model in a gridsearch so we can compare with our original result.

pipe = Pipeline([
    ('scale', StandardScaler()),
    ('model', DummyClassifier())

grid = GridSearchCV(estimator=pipe, 
                    param_grid={'model__strategy': ['stratified', 'most_frequent', 'uniform']}, 
                    scoring={'acc': make_scorer(accuracy_score)}, 

grid.fit(X, y);

To see the gridsearch results you can run;

pd.DataFrame(grid.cv_results_)[['param_model__strategy', 'mean_test_acc']]
