Learn how a classification threshold can be set to convert a logistic regression model into a binary classification model, and how to use a confusion matrix to assess the four types of predictions: true positive (TP), true negative (TN), false positive (FP), and false negative (FN).
In statistics and machine learning, loss measures the difference between the predicted and actual values. Loss focuses on the distance between the values, not the direction. For example, if a model predicts 2, but the actual value is 5, we don't care that the loss is negative $ -3 $ ($ 2-5=-3 $).
