Abstract By using the kernel trick to modify Hopfield autoassociative memory model (HAM), a framework of kernel autoassociation memory model (KAM) is proposed. KAM makes exponential correlation associative memory (ECAM) and improved ECAM (IECAM) become two special cases. Then, the framework of distance weighted 2D kernel autoassociation memory model (DW2DKAM) is constructed by introducing distance factors to the kernels. DW2DKAM improves the storage capacity and errorcorrecting capability of KAM when recognizing binary visual images. Simulation results verify that DW2DKAM has higher storage capacity and better errorcorrecting capability than those of KAM, and outperforms the recently proposed modular HAM by Seow and Asari.
