ON THE MULTI-NEURON INTERACTION-MODEL WITHOUT TRUNCATING THE INTERACTION

A replica-symmetric mean-field theory approach is presented to the mul ti-neuron interaction model introduced by de Almeida and Iglesias (199 0 Phys. Lett. 146A 239). Fixed-point equations are derived for the rel evant order parameters of the model, extended to include biased patter ns, without truncating the interaction. The capacity-bias and the temp erature-capacity phase diagrams are discussed. Compared with the trunc ated version of the model, it is found that the capacity at zero tempe rature is infinite and that the retrieval states satisfy the de Almeid a-Thouless stability condition.
