Using the logistic regression algorithm for the classifiers challenge

In this section, we will see how we can use the logistic regression algorithm for the classifiers challenge:

1. First, let's instantiate a logistic regression model and train it using the training data:

from sklearn.linear_model import LogisticRegressionclassifier = LogisticRegression(random_state = 0)classifier.fit(X_train, y_train)

2. Let's predict the values of the test data and create a confusion matrix:

y_pred = classifier.predict(X_test)cm = metrics.confusion_matrix(y_test, y_pred)cm

We get the following output upon running the preceding code:

3. Now, let's look at the ...
