Jitter, английский
- Дрожание, флуктуация. быстрые небольшие скачки вверх-вниз символов или точек на экране дисплея
- Дрожь
- Фазовая разность между сигналом, исходящим от источника, и сигналом, поступившем на приёмник
- Small, rapid variations in a waveform due to mechanical disturbances or to changes in the characteristic of components. supply voltages, imperfect synchronizing signals, circuits, etc.
- The variation in time of a received signal compared to the instance of its transmission or compared to a fixed time frame at the receiver. examples of jitter sources include signal-pattern-dependent laser turn-on delay jitter, noiseinduced jitter on a gating turn-on point, gating hysteresis jitter, and gating jitter that accumulates in a link between two nodes
- Small and rapid variations in the timing of a waveform due to noise, changes in component characteristics, supply voltages, imperfect synchronizing circuits, etc. see also ddj, dcd, and rj. also called phase jitter, timing distortion, or inter-symbol interference. the slight movement of a transmission signal in time or phase that can introduce errors and loss of synchronization. the amount of jitter will increase with longer cables, cables with higher attenuation, and signals at higher data rates.
- Синхроимпульсы, вводи- 6-2 -4 3 - мые в полезный сигнал см.также jittered pulses
- One method to avoid over-fitting is to use jittering in training data. noise is deliberately added to the training data. this is a sampling-based form of smoothing and works well when the model is trying to estimate a smooth relationship. this technique will, however, obscure any discontinuities that are in the underlying relationship. this is closely related to such techniques as kernel techniques, where the data points are replaced by multivariate distributions and ridge regressions, which add "prior" information to the regression function. choosing the size of the jitter is equivalent to the statistical problem of choosing a kernel bandwidth or the size of the prior information in the ridge regression. see also: kernel function, kernel regression. j-measure the j-measure is a scoring rule for association rules. in evaluation of a rule of the form "if x occurs, then y will occur," with a given frequency (support) and confidence, the j-measure provides a single measure that trades off rule frequency and rule confidence. the j-measure is the product of the probability of x, the if part of the rule, with the cross-entropy of the rule. see also: association rules, cross entropy.
Jitter distortion, английский
Случайное искажение; искажение из-за наводок; дрожание

Jitterbug, английский
- A tamper, usually pneumatic, for concrete. job 1.

Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].
