NegativeIt refers to the category opposite to the positive class in binary classification. In binary classification problems, there are two types of dependent variables: negative and positive. It can be written as the dependent variable y ∈ { 0 , 1 } , where 0 represents the negative class and 1 represents the positive class.

The positive class is the target we need, and the negative class is another possibility. For example, the negative class in medical testing may be "non-tumor", and the negative class in an email classifier may be "non-spam".
