The relative order of a class of recurrent networks

Three types of recurrent network configurations have been proposed since they enable adequate description of temporal behaviour. The concept of relative order has been introduced so as to provide a framework for analysing such network configurations. It has been demonstrated that, excluding pathologies, each configuration is of relative order unity. Therefore it follows that an inverse exists for each type of configuration (Tsinias and Kalouptsidis, 1983; Hirschorn, 1979).
