Abstract
We present a methodology for the extraction of rules from Artificial Neural Networks (ANN) trained to forecast the electric load demand. The rules have the ability to express the knowledge regarding the behavior of load demand acquired by the network during training process. The rules are presented to the user in an easy to read format, such as IF premise THEN consequence. Where premise relates to the input data submitted to the network (mapped as fuzzy sets), and consequence appears as a linear equation describing the output to be presented by the network, should the premise part holds true. Experimentation demonstrates the method’s capacity for acquiring and presenting high quality rules from neural networks trained to forecast electric load demand for several amounts of time in the future.
