Abstract
Three different sparsely encoded associative memories (SEAMs) are quantitatively analyzed. The first two models are shown to have performance inferior to that of nonsparse systems due to stored-pattern mutual interference. Assuming that each neuron is working close to its threshold and using dynamic thresholding selection, the binary SEAM performance can be improved. The simulation results are consistent with the theoretical work. The sensitivity problem that arises in choosing the threshold range is also explored
