Erratum to: Smart pathological brain detection system by predator-prey particle swarm optimization and single-hidden layer neural-network

Abstract

In order to develop an artificial intelligence and computer-aided diagnosis system that assists neuroradiologists to interpret magnetic resonance (MR) images. This paper employed Hu moment invariant (HMI) as the brain image features, and we proposed a novel predator-prey particle swarm optimization (PP-PSO) algorithm used to train the weights of single-hidden layer neural-network (SLN). We used five-fold stratified cross validation (FFSCV) for statistical analysis. Our proposed HMI + SLN + PP-PSO method achieved a sensitivity of 96.00 ± 5.16%, a specificity of 98.57 ± 0.75%, and an accuracy of 98.25 ± 0.65% for the DA-160 dataset, and yields a sensitivity of 97.14 ± 2.33%, a specificity of 97.00 ± 0.34%, and an accuracy of 97.02 ± 0.33% for the DA-255 dataset. Our method performs better than six state-of-the-art approaches.
