When modeling a multi-class classification problem, the data must be prepared. The target variable containing the class labels is first label encoded, meaning that an integer is applied to each class label from 0 to N-1, where N is the number of class labels. WebThe complement of an event A A is denoted as A^c Ac or A' A′. An event and its complement are mutually exclusive and exhaustive. This means that in any given experiment, either the event or its complement will happen, but not both. By consequence, the sum of the probabilities of an event and its complement is always equal to 1. flatbed tool boxes aluminum
