What's the difference between noise and stochasticity?

Noise


Definition:

  • (n.) Sound of any kind.
  • (n.) Especially, loud, confused, or senseless sound; clamor; din.
  • (n.) Loud or continuous talk; general talk or discussion; rumor; report.
  • (n.) Music, in general; a concert; also, a company of musicians; a band.
  • (v. i.) To sound; to make a noise.
  • (v. t.) To spread by rumor or report.
  • (v. t.) To disturb with noise.

Example Sentences:

  • (17) The footballer said the noise of the engine was too loud to hear if Cameron snored but his night "wasn't the best".
  • (18) Although a clean step response or the ensemble average of several responses contaminated with noise is needed for the generation of the filter, random noise of magnitude less than or equal to 0.5% added to the response to be corrected does not impair the correction severely.
  • (19) A final experiment confirmed a prediction from the above theory that when recalling the original sequence, omissions (recalling no word) will decrease and transpositions (giving the wrong word) will increase as noise level increases.
  • (20) A grassed roof, solar panels to provide hot water, a small lake to catch rainwater which is then recycled, timber cladding for insulation ... even the pitch and floodlights are "deliberately positioned below the level of the surrounding terrain in order to reduce noise and light pollution for the neighbouring population".

Stochasticity

Example Sentences:

  • (1) We assumed that the sensory messages received at a given level are transformed by a stochastic process, called Alopex, in a way which maximizes responses in central feature analyzers.
  • (2) The capacity of granule-cell networks to separate overlapping patterns of activity on their inputs is adequate, with spatial variability in the secretion at synapses, but is improved if there is also temporal variability in the stochastic secretion at individual synapses, although this is at the expense of reliability in the network.
  • (3) The estimation of an expected number of the stochastic effects caused by the internal exposure to ionizing radiation from the administered radionuclides have been performed for the patients according to ICRP recommendations.

  • (8) A mutation from one state into another in such system ('bioids') involves an amplification of different 'kinds of information', as 'stochastic' (noise into dissipative structures), 'molecular' (autocatalysts), and 'stoichimetric' information.
  • (9) Estimators of the model parameters are defined under general exact and stochastic linear constraints.
  • (10) These ideas have been incorporated in a Monte Carlo computer program using Poisson statistics to treat the stochastic nature of the energy deposition processes and thereby determine the excitation and ionization states of the molecule.
