“…The fusion of FSs with NNs or WNNs in a single network is an effective method to overcome their individual limitations. However, the fused network of Chairez [15] and the FWNN of Tsai et al [16] are expansions of ANFIS [21,22], where different training algorithms are used to adjust the network structure and parameters. Therefore, these fused approximators inherit the difficulties of ANFIS.…”
