Visualizing decision boundaries
In this exercise, you'll visualize the decision boundaries of various classifier types.
A subset of scikit-learn's built-in wine dataset is already loaded into X, along with binary labels in y.

Petunjuk latihan
- Create the following classifier objects with default hyperparameters:
LogisticRegression,LinearSVC,SVC,KNeighborsClassifier. - Fit each of the classifiers on the provided data using a
forloop. - Call the
plot_4_classifers()function (similar to the code here), passing inX,y, and a list containing the four classifiers.
