... networks in the nervous system. In all these cases, the component units (the genes, proteins or neurons) can be activated (turned on, excited) or deactivated (turned off, inhibited) to varying degrees at different times by other units in the network. For example, when a gene is turned on it is trans ...

Supervised learning
... The neuron can be in two states • excited, if s = 1 • not excited, if s = 0 Thus, a neuron is going to separate the space of inputs with an hyperplan. This is why a neural network is good at classification. The action of a single neuron is quite easy ; only the cooperation of a great number of neuro ...
