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.
Vibration, английский
- Вибрация; вибрационный
- Вибрация, колебание; колебательное движение
- As applied to concrete,
- Rapid and continuous movement speech is formed by the vibrations of the vocal cords.
- Вибрация
- The undesirable oscillatory movements of the drill string.
Chatter, английский
- The sawtooth pattern along a cut line on artwork caused by an uneven application
- A дребезжащий
- Дрожание; вибрация
- See: whipsawed
- Any irregular or jerky motion of a component, as for example a wiper blade over glass, or the noise associated therewith, check valve (1) hydraulic valve that maintains a residual pressure in a brake system when the brake is not applied. (2) valve to control flow of air or mixture
- In machining or grinding, (1) a vibration of the tool, wheel or workpiece producing a wavy surface on the work. (2) the finish produced by such vibration.
- (1) in machining or grinding, vibration of tool, wheel or workpiece producing a wavy surface on the work. chatter marks on the surface finish are produced by a vibrating machining tool
- In machining or grinding, vibration of tool, wheel, or workpiece producing a wavy surface on the work. chatter marks on the surface finish are produced by a vibrating machining tool.
Dither, английский
To create the illusion of varying shades of gray on a monochrome display or printer or of additional colors on a color display or printer.
Wobble, английский
In electromagnetic testing, an effect that produces variations in an output signal of a test system caused by probe rocking on a surface or coil displacement within an encircling coil. often used to set variable phase displays to a horizontal orientation as a means for standardizing signal presentations on vector displays.
