Sapling. Phyllanthus acidus is an intermediary between a shrub and tree, reaching 2 to 9 m (6½ to 30 ft) high. [2] The tree's dense and bushy crown is composed of thickish, tough main branches, at the end of which are clusters of deciduous, greenish, 15-to-30-cm long branchlets.
Information foraging is a theory that applies the ideas from optimal foraging theory to understand how human users search for information. The theory is based on the assumption that, when searching for information, humans use "built-in" foraging mechanisms that evolved to help our animal ancestors find food.
The information bottleneck method is a technique in information theory introduced by Naftali Tishby, Fernando C. Pereira, and William Bialek. [1] It is designed for finding the best tradeoff between accuracy and complexity (compression) when summarizing (e.g. clustering) a random variable X, given a joint probability distribution p(X,Y) between X and an observed relevant variable Y - and self ...
The choice of logarithmic base in the following formulae determines the unit of information entropy that is used. A common unit of information is the bit or shannon, based on the binary logarithm. Other units include the nat, which is based on the natural logarithm, and the decimal digit, which is based on the common logarithm.
The inference engine uses general-purpose reasoning methods to infer new knowledge and to solve problems in the problem domain. Most commonly, it employs forward chaining or backward chaining . Other approaches include the use of automated theorem proving , logic programming , blackboard systems , and term rewriting systems such as Constraint ...
Digital literacy combines both technical and cognitive abilities; it consists of using information and communication technologies to create, evaluate, and share information. [ 1 ] Digital literacy initially focused on digital skills and stand-alone computers, but the advent of the internet and social media use has shifted some of its focus to ...
The following is provided as an overview of and topical guide to databases: Database – organized collection of data, today typically in digital form. The data are typically organized to model relevant aspects of reality (for example, the availability of rooms in hotels), in a way that supports processes requiring this information (for example, finding a hotel with vacancies).
In distributed computing, a single system image (SSI) cluster is a cluster of machines that appears to be one single system. [1] [2] [3] The concept is often considered synonymous with that of a distributed operating system, [4] [5] but a single image may be presented for more limited purposes, just job scheduling for instance, which may be achieved by means of an additional layer of software ...
