Abstract
In this work, we shall put forward a novel chaos memory retrieval model with a Chebyshev-type activation function as an artificial chaos neuron. According to certain numerical analyses of the present association model with autocorrelation connection matrix between neurons, the dependence of memory retrieval properties on the initial Hamming distance between the input pattern and a target pattern to be retrieved among the embedded patterns will be presented to examine the retrieval abilities, i.e. the memory capacity of the associative memory.
