Loss function Facts for Kids. *Kiddle Encyclopedia.*

In mathematics a **loss function** or **cost function** is a mathematical function that maps an event, or the values of one or more variables onto a real number. This number is then given a semantic value, such as cost or utility. Optimisation can then be used to find the value where the function is minimal, or at one of its maxima.
