Abstract

This paper proposes a Particle Swarm Optimization-based Weighted-Nadaraya-Watson (PSO-WNW) estimator which uses the standard PSO algorithm to choose the optimal weights for WNW estimator. PSO-WNW estimator gives up the weight constraints of the classical WNW estimator, which makes PSO algorithm to find the more appropriate weights. The estimation performances of PSO-WNW estimator are tested based on 6 well-known testing functions. The experimental results show that PSO-WNW estimator can further reduce the training and testing Root Mean Square Errors (RMSEs) of WNW estimator for any given bandwidth parameter and demonstrate the feasibility and effectiveness of PSO-WNW estimator.
