Feature interaction is a software engineering concept. It occurs when the integration of two features would modify the behavior of one or both features. The term feature is used to denote a unit of functionality of a software application. Similar to many concepts in computer science, the term can be used at different levels of abstraction.
An interaction variable or interaction feature is a variable constructed from an original set of variables to try to represent either all of the interaction present or some part of it. In exploratory statistical analyses it is common to use products of original variables as the basis of testing whether interaction is present with the ...
Human interactivity. Across the many fields concerned with interactivity, including information science, computer science, human-computer interaction, communication, and industrial design, there is little agreement over the meaning of the term "interactivity", but most definitions are related to interaction between users and computers and other machines through a user interface.
In pattern recognition and machine learning, a feature vector is an n-dimensional vector of numerical features that represent some object. Many algorithms in machine learning require a numerical representation of objects, since such representations facilitate processing and statistical analysis.
Interaction design, often abbreviated as IxD, is "the practice of designing interactive digital products, environments, systems, and services." [ 1 ] : xxvii, 30 While interaction design has an interest in form (similar to other design fields), its main area of focus rests on behavior.
Data, context, and interaction (DCI) is a paradigm used in computer software to program systems of communicating objects. Its goals are: Its goals are: To improve the readability of object-oriented code by giving system behavior first-class status;
Feature level fusion is believed to be more effective than the other levels of fusion because the feature set contains richer information about the input biometric data than the matching score or the output decision of a classifier. Therefore, fusion at the feature level is expected to provide better recognition results. [24]
An interaction technique is a way of using a physical input/output device to perform a generic task in a human-computer dialogue. [1] A more recent variation is: An interaction technique is the fusion of input and output, consisting of all software and hardware elements, that provides a way for the user to accomplish a task. [2]
