[9] [10] Assuming a simple ensemble of classifiers is assembled via averaging the outputs, then the amended cross-entropy is given by = (,) (,) where is the cost function of the classifier, is the output probability of the classifier, is the true probability to be estimated, and is a parameter between 0 and 1 that defines the 'diversity' that ...
Observe that a logarithm mediates between these two operations. The conditional entropy and related quantities inherit simple relation, in turn. The measure theoretic definition in the previous section defined the entropy as a sum over expected surprisals () for an extremal partition. Here the logarithm is ad hoc and the entropy is not a ...
Another meaning of range in computer science is an alternative to iterator. When used in this sense, range is defined as "a pair of begin/end iterators packed together". [1] It is argued [1] that "Ranges are a superior abstraction" (compared to iterators) for several reasons, including better safety.
Average true range – averaged daily trading range, adjusted for price gaps. Breakout – the concept whereby prices forcefully penetrate an area of prior support or resistance, usually, but not always, accompanied by an increase in volume. Chart pattern – distinctive pattern created by the movement of security or commodity prices on a chart
A benefit of the square loss function is that its structure lends itself to easy cross validation of regularization parameters. Specifically for Tikhonov regularization , one can solve for the regularization parameter using leave-one-out cross-validation in the same time as it would take to solve a single problem.
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
In computer programming, bounds checking is any method of detecting whether a variable is within some bounds before it is used. It is usually used to ensure that a number fits into a given type (range checking), or that a variable being used as an array index is within the bounds of the array (index checking).
In computer science, the range query problem consists of efficiently answering several queries regarding a given interval of elements within an array. For example, a common task, known as range minimum query , is finding the smallest value inside a given range within a list of numbers.
