    Binary classification problems (target/non-target) are often modeled as a pair where is our model, which maps input vectors to scores, and is our threshold, such that we predict to be of target class iff . Otherwise, we predict it to be of non-target class. The threshold is usually set to , but this needs not […]

For example, you can open python3 and run the following. So a normal, every-day int in python can easily store […]
