One of the main problems for modeling the electric power consumption in a certain place is the extraction of the knowledge when it is stored in big volumes of information like for example historical registrations. According with this representation, each fact happened and registered consists of a couple of components (t, P) where t represents the time of sample registration and P the electric power consumed at that time. The daily registration has N cases that each of the well-known stimulus-answer couples represents. The objective of this work is to develop a function that allows finding the vector of entrance variables t to the vector of exit variables P. F is any function, in this case the electric power consumption. Their modeling with Artificial Neural Netwok (ANN) is Multi a Perceptron Layer (PMC). Another form of modeling it is using Interpolation Algorithms(AI).
