Hi everyone,

I am training scikit learn a bit. I was trying to do a ridge classifier on breast_cancer dataset. How can I plot the classifier line to show the boundaries?

Here the code I used:

import numpy as np
from sklearn import datasets
import pandas as pd
import matplotlib.pyplot as plt
from sklearn.linear_model import RidgeClassifier
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler

data = datasets.load_breast_cancer(as_frame=True)

X = data.data
X = StandardScaler().fit_transform(X)
y = data.target
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=.4, random_state=42)
clf = RidgeClassifier()
clf.fit(X_train, y_train)
score = clf.score(X_test, y_test)
y_pred = clf.predict(X_test)
