WebInformation processing theory is the approach to the study of cognitive development evolved out of the American experimental tradition in psychology. Developmental psychologists who adopt the information processing perspective account for mental development in terms of maturational changes in basic components of a child's mind. The …

WebInformation flow in an information theoretical context is the transfer of information from a variable to a variable in a given process.Not all flows may be desirable; for example, a system should not leak any confidential information (partially or not) to public observers--as it is a violation of privacy on an individual level, or might cause major loss on a corporate …

WebOrganizational Information Theory (OIT) is a communication theory, developed by Karl Weick, offering systemic insight into the processing and exchange of information within organizations and among its members. Unlike the past structure-centered theory, OIT focuses on the process of organizing in dynamic, information-rich environments. Given ...

WebIn mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements (nodes or edges) that need to be removed to separate the remaining nodes into two or more isolated subgraphs. It is closely related to the theory of network flow problems. The connectivity of a graph is an …

WebIn graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees.. A …

WebIn information theory, the information content, self-information, surprisal, or Shannon information is a basic quantity derived from the probability of a particular event occurring from a random variable.It can be thought of as an alternative way of expressing probability, much like odds or log-odds, but which has particular mathematical advantages in the …

WebThe smiley face murder theory (also known as the smiley face murders, smiley face killings, and smiley face gang) is a theory advanced by retired New York City detectives Kevin Gannon and Anthony Duarte, as well as Dr. Lee Gilbertson, a criminal justice professor and gang expert at St. Cloud State University. It alleges that a number of young …

WebIn mathematics, the order of a finite group is the number of its elements. If a group is not finite, one says that its order is infinite.The order of an element of a group (also called period length or period) is the order of the subgroup generated by the element.If the group operation is denoted as a multiplication, the order of an element a of a group, is thus the …

WebPublication. The article was the founding work of the field of information theory. It was later published in 1949 as a book titled The Mathematical Theory of Communication (ISBN 0-252-72546-8), which was published as a paperback in 1963 (ISBN 0-252-72548-4).The book contains an additional article by Warren Weaver, providing an overview of the theory for …

WebIn information theory and machine learning, information gain is a synonym for Kullback–Leibler divergence; the amount of information gained about a random variable or signal from observing another random variable. However, in the context of decision trees, the term is sometimes used synonymously with mutual information, which is the …
