1. A method of object recognition by a computerized spiking neuron network comprising first and second spiking neurons, the method comprising, for a signal comprising first and second representations of first and second objects, respectively: based on a first response by the first neuron to a representation of at least one of the first and the second objects: potentiating a first feed-forward connection delivering the signal to the first neuron; and incrementing an inhibition indication for the second neuron; and based on a second response by the second neuron to the representation of at least one of the first and the second objects: depressing a second feed-forward connection delivering the signal to the second neuron; and incrementing an inhibition indication for the first neuron.
