Sentences with phrase «stochastic resonance»
Stochastic resonance is a scientific concept that suggests noise or random fluctuations can enhance the performance or detection of weak signals in a system. It means that sometimes, adding just the right amount of randomness can improve the overall functioning, sensitivity, or efficiency of a system. Full definition
While noise is often understood as an obstacle to a signal carrying a message, the phenomenon of stochastic resonance indicates cases where the presence of white noise (that is, randomness) actually helps amplify the signal.

Given that Rakowitz often deals with objects and histories that are lost and proposes ways to reconstitute them imperfectly, stochastic resonance seems a fitting way to understand the material substitutions he makes.
A team of Japanese researchers has discovered a new mechanism to explain stochastic resonance, in which sensitivity to weak signals is enhanced by noise.
Our papers on DO events triggered by stochastic resonance are here and here.
Some unknown natural forcing exists with a period of 1470 yrs, and the climate system is subject to stochastic resonance during glacials.
I know about a physical phenomenon called «stochastic resonance»: Some noisy systems may greatly amplify weak signals, expecially if thresholds are involved.
[Response: On the other hand please see our paper showing where the stochastic resonance idea may be wrong.
Don't get me wrong here; I think the papers Stefan cites are important, and largely correct, but the statistics supporting «stochastic resonance» as a good model are simply not convincing, at least to me.
(El Nino et al is possibly not modellable in principle beyond predicting statistics of ocean weather: Stochastic resonance.)
As the wikipedia entry on Bond events says, ``... the 1,500 - year cycle displays nonlinear behavior and stochastic resonance.»
