uncertainty | - Неизвестность. неопределенность.
- Неопределенность. недостоверность. сомнительность. ненадежность.
- Неопредел
- Неопределенность. параметр, связанный с результатом измерения, характеризующий дисперсию значений, которые могут быть обоснованно отнесены к аналиту. таким параметром может быть, например, среднеквадратическое откло-нение (или кратное ему) или ширина доверительного интервала. также: оценка, относящаяся к результату проверки, которая характеризует область значений, внутри которой лежит истинное значение.
- The (average) number of binary decisions a decision maker has to make in order to select one out of a set of mutually exclusive alternatives, a measure of an observer`s ignorance or lack of information (->bit). since the categories within which events are observed are always specified by an observer, the notion of uncertainty emphasises the cognitive dimension of information processes, specifically in the form of measures of variety, statistical entropy including noise and equivocation. 78

uncertainty factor | Mathematical adjustments for reasons of safety when knowledge is incomplete. for example, factors used in the calculation of doses that are not harmful (adverse) to people. these factors are applied to the lowest-observed-adverse-effect-level (loael) or the no-observed-adverse-effect-level (noael) to derive a minimal risk level (mrl). uncertainty factors are used to account for variations in people`s sensitivity, for differences between animals and humans, and for differences between a loael and a noael. scientists use uncertainty factors when they have some, but not all, the information from animal or human studies to decide whether an exposure will cause harm to people [also sometimes called a safety factor]. | |
uncertainty of measurement | Parameter, associated with the result of a measurement, that characterizes the dispersion of the values that could reasonably be attributed to the measurand (1,4) | |
uncertainty principle | A principle in quantum physics, formulated by heisenberg | |
uncertainty propagation | Uncertainty propagation refers to the process of updating or revising the uncertainty measures of a set of propositions or attributes due to changes in assumption or information about related propositions or attributes. in some contexts, propagation is separated from revision, where the latter term is used to refer to the mutual change in uncertainty for a set of propositions when new knowledge is introduced into the system. | |
uncertainty sampling | A method for selecting cases to train classifiers that produce probabilistic output. after the initial training of a classifier, a series of observations are run through the program, and ranked according to the uncertainty of the predictions. the most uncertain ones are selected, properly classified, and used to train the classifier further. this can be repeated until the classifier performs satisfactorily. | |
