Improvement of Grey System Model using Particle Swarm Optimization [PDF]
Journal of Electrical Systems and Information Technology, 2020 AbstractAn improvement of the traditional grey system model, GM(1,1), to enhance forecast accuracy, has been realized using the particle swarm optimization (PSO) algorithm. Unlike the GM(1,1) which uses a fixed adjacent neighbor weight for all data sets, the proposed PSO-improved model, PSO-GM(1,1), determines an optimal adjacent neighbor weight, based
