Grossberg network is an artificial neural network introduced by Stephen Grossberg. It is a self organizing, competitive network based on continuous time. 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
formula_1,
where formula_2 represents the activation level of a neuron, formula_3 and formula_4 represent the excitatory and inhibitory inputs to the neuron, and formula_5, formula_6, and formula_7 are constants representing the leaky decay rate and the maximum and minimum activation levels.
At equilibrium (where formula_8), the activation formula_9 reaches the value
formula_10.
