It is just a function that actions the effectiveness of a Equipment Finding out model for specified knowledge. Price Functionality quantifies the error concerning predicted values and anticipated values and offers it in the form of only one actual number. Depending upon the difficulty Cost Purpose may be fashioned in many various means. The objective of Cost Operate is to be both:
Minimized - then returned value is normally known as cost, reduction or mistake. The objective will be to find the values of design parameters for which Price tag Operate return as small amount as feasible.
Maximized - then the value it yields is named a reward. The target is to locate cost function in machine learning values of design parameters for which returned number is as huge as feasible.
