For a machine learning progress, how should you split data for training and evaluation?

HOTSPOT You are developing a model to predict events by using classification. You have a confusion matrix for the model scored on test data as shown in the following exhibit. Use the drop - down menus to select the answer choice that completes each statement based on the information presented in the graphic. NOTE: Each correct selection is worth one point. Answer: Explanation: Box 1: 11 TP = True Positive. The class labels in the training set can take on only two possible values, which we usually refer to as positive or negative.
