Probabilistic computing is another expression of bio-inspired computing.
Indeed, noise is often a key element of bio computation, beneficial for a number of operations as near-threshold signaling and
decision making. For instance stochastic resonance, a noise induced sensitivity improvement , exists at the neural level.
Stochastic binary behaviors are also often observed in cell signaling pathways: neurotransmitter release through the synaptic
cleft or the opening/closing of ionic channels are probabilistic biological processes. In general, stochastic computing trades
absolute accuracy against considerable energy gains.
