1. Shape recognition

A model can be used to predict the reactions or outputs of a real system, such as manufacturing systems, transportation systems, or energy production and distribution systems, in response to specific actions or inputs. The purpose of building a model is to understand the behavior(s) of a real system in order to control it or optimize its performance. Several methods can be used to build a model. When a priori knowledge of the behavior of a real system is not sufficient to build a physical, analytical or mathematical model, Pattern Recognition (PR) methods
