For a given recurrent neural network, a discrete-time model may have asymptotic dynamics di erent from the one of a related continuous-time model. In this paper, we consider a discretetime model that discretizes the continuous-time leaky integrator model and study its parallel, sequential, block-sequential and distributed dynamics for symmetric networks. We… (More)
We study the convergence behavior of a learning model with generalized Hebbian synapses. 2002 Elsevier Science (USA). All rights reserved.
Autism spectrum disorders (ASDs) are a triad of disturbances affecting the areas of communication, social interaction and behavior. In educational contexts, without appropriate intervention methodologies, these limitations can be deeply disabling. Our research promotes the communicative competence of children with ASDs It extends the current… (More)
We prove that except possibly for small exceptional sets, discretetime analog neural nets are globally observable, i.e. all their corrupted pseudo-orbits on computer simulations actually reflect the true dynamical behavior of the network. Locally finite discrete (boolean) neural networks are observable without exception.
We study the existence and stability of pulse stationary solutions of an integrodifferential equation modelling the coarse-grained averaged activity of a single layer of interconnected neurons. The neuronal connections considered are laterally oscillatory with an exponential rate of decay and variable phase. We identify regions in the parameter space where… (More)
We study the existence and stability of stationary solutions of an integro-differential equation modelling the activity of a single layer of interconnected neurons. The multi-parameter neural connections considered incorporate lateral oscillations with an exponential rate of decay. We identify regions in the parameter space where solutions exhibit areas of… (More)
This paper describes a framework, devised for rapid application development, and rapid application customization of standalone multimedia and rich content software, targeted at students with special needs. We present a proof-of-concept software application for promotion and training of social communication skills in children with autism spectrum disorders.… (More)
