Фазовое дрожание хронирующих импульсов, русский

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.

- 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.

Timber, английский
- A wooden bearer which is used to support crossingwork assemblies.
- General term applied to forests and their products.
- A general term for natural or sawn wood in a form suitable for building or structural purposes.
- Пороки древесины, пороки лесоматериалов; ~s on the plaster
- A specialized trailer, used for transporting logs, consisting of a basic chassis with vertical stakes along the sides to hold the logs in place. there are several types of timber trailers: long wood trailers; usually with four stakes, but can have more, evenly spaced for tree length logs to be carried longwise on the trailer; short wood trailers, with two separated sets of four of stakes, commonly referred to as a double bunk, and piggyback trailers. these trailers can be self loaded onto the back of a truck
