Locally Connected BSB Neural Networks as Associative Memories Storing Grey-Scale Images

In this paper, we introduce an associative memory storing grey scale images. It’s based on a suitable translation of the grey scale image into a Gray-coded binary image, stored in a single BSB binary neural network. The particular BSB we are going to exploit has the property of local connectivity. The chosen learning algorithm guarantees asymptotic stability of the stored patterns, low computational cost, and control of the connection weights precision, without multiplication.
