Grossberg network
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
,
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
