| Abstract(in English) | Coolen-Sherrington (CS) theory approximately describes the retrieval dynamics of the autocorrelation associative memory, but there remains deviations between the theory and simulations. We consider direct meaning of the assumption of "equipartitioning of probability in the macroscopic (m, r) subshells, "employed by the CS theory, and show that it corresponds to assuming the Gibbs distribution of the model with certain values of temperature and bias. We demonstrate by computer simulations that the deviations between the CS theory and simulations are due to the error in noise distributions, which comes from the equipartitioning assumption, and that the phenomena (Amari-Maginu), that the model dynamics selects microstates which are not typical within the set specified by the values of macroscopic state variables, can be observed when one chooses the macroscopic state variables as chosen in the CS theory. |
