Cost management is the process of planning and controlling the costs associated with running a business. It includes collecting, analyzing and reporting cost information to more effectively budget, forecast and monitor costs. Cost management practices can be applied to specific projects or to the company's overall operating model.

We're going to define the cost as the penalty that the algorithm pays if it outputs a value which is some number like 0.7. And the actual cost label turns out to be y. The cost is going to be if y=1. And if y=0. This looks like a pretty complicated function.
