Abstract: By introducing the kernel method into conventional auto-associative memory model (AM), a unified framework of kernel auto-associative memory model (KAM) is established, which extends the existing AM. Taking into account the complex full connectivity of KAM, and based on the small-world network described by Watts and Strogatz, this paper proposes a framework of small-world architecture based kernel auto-associative memory model (SWA-KAM), making VLSI implementation of AM easier.Simulation results on FERET face image database show that, SWA-KAM is more robust and has higher recognition rate than both PCA and (PC)2A algorithms in the presence of additive noise or partial occluding on face images.
