In information theory, perplexity is a measure of uncertainty in the value of a sample from a discrete probability distribution. The larger the perplexity, the less likely it is that an observer can guess the value which will be drawn from the distribution.
In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
The feature with the optimal split i.e., the highest value of information gain at a node of a decision tree is used as the feature for splitting the node. The concept of information gain function falls under the C4.5 algorithm for generating the decision trees and selecting the optimal split for a decision tree node. [1] Some of its advantages ...
The theory of motivated information management (TMIM) is a social-psychological framework that examines the relationship between information management and uncertainty.TMIM has been utilized to describe the management of information regarding challenging, taboo, or sensitive matters.
Neglect of probability, the tendency to completely disregard probability when making a decision under uncertainty. [52] Scope neglect or scope insensitivity, the tendency to be insensitive to the size of a problem when evaluating it. For example, being willing to pay as much to save 2,000 children or 20,000 children.
Ambiguity tolerance–intolerance was formally introduced in 1949 through an article published by Else Frenkel-Brunswik, who developed the concept in earlier work on ethnocentrism in children [3] In the article which defines the term, she considers, among other evidence, a study of schoolchildren who exhibit prejudice as the basis for the existence of intolerance of ambiguity.
Uncertainty about the flow of information is not recommended, as a poorly organized communication structure leads to lax monitoring and can also limit the opportunities for detecting errors. Quality control is also responsible for the identification of actions necessary for correcting faulty data collection practices and also minimizing such ...
A loss of $0.05 is perceived as having a greater utility loss than the utility increase of a comparable gain. In cognitive science and behavioral economics, loss aversion refers to a cognitive bias in which the same situation is perceived as worse if it is framed as a loss, rather than a gain.
