Question

How can I create a confusion matrix in Python?

Answer 1

You can use the scikit-learn library in Python to create a confusion matrix. Here's an example code snippet:

from sklearn.metrics import confusion_matrix

# Assuming you have true labels and predicted labels
true_labels = [0, 1, 0, 1, 1, 0]
predicted_labels = [0, 1, 1, 1, 0, 0]

# Create a confusion matrix
cm = confusion_matrix(true_labels, predicted_labels)

print(cm)
 

This code will output the confusion matrix in the form of a 2x2 array:

[[2 1]
 [1 2]]
