Grossberg network is an artificial neural network introduced by Stephen Grossberg. It is a self organizing, competitive network based on continuous time.[1] Grossberg, a neuroscientist and a biomedical engineer, designed this network based on the human visual system.
Shunting model
The shunting model is one of Grossberg's neural network models, based on a Leaky integrator, described by the differential equation
- ,
where represents the activation level of a neuron, and represent the excitatory and inhibitory inputs to the neuron, and , , and are constants representing the leaky decay rate and the maximum and minimum activation levels.
At equilibrium (where ), the activation reaches the value
