Concurrent object-oriented simulation of neural network models

The analysis of complex neural network models via analytical techniques is often quite difficult due to the large numbers of components involved, and the nonlinearities associated with these components. For this reason, simulation is seen as an important tool in neural network research. A framework for simulating neural networks as discrete event nonlinear dynamical systems is presented. This includes neural network models whose components are described by continuous-time differential equations, or by discrete-time difference equations. The design and construction of a concurrent object-oriented discrete event simulation environment for neural networks is considered. The use of an object-oriented language provides the data abstraction facilities necessary to support modification and extension of the simulation system at a high level of abstraction. The ability to specify concurrent processing supports execution on parallel architectures. The use of this system is demonstrated by simulating a specific neural network model (ART1) on a general-purpose parallel computer (bus based shared memory system)
