Filter feature selection is a specific case of a more general paradigm called structure learning.Feature selection finds the relevant feature set for a specific target variable whereas structure learning finds the relationships between all the variables, usually by expressing these relationships as a graph.
Feature integration theory is a theory of attention developed in 1980 by Anne Treisman and Garry Gelade that suggests that when perceiving a stimulus, features are "registered early, automatically, and in parallel, while objects are identified separately" and at a later stage in processing.
Feature detectors were also observed in these brain regions. Neurons were observed to be either directionally-sensitive to looming large objects, size-selective or perceptive to stationary obstacles. Certain pretectal thalamic neurons, type TH3, showed a preference for big moving objects and the anti-worm configuration of moving bar stimuli. [17]
This fueled the development of the memory selection model, which shares the same basic principle of early selection models that stimulus features are selected via their physical properties. [3] However, attended and unattended information pass through the filter, to a second stage of selection on the basis of semantic characteristics or message ...
Object-based attention refers to the relationship between an ‘object’ representation and a person’s visually stimulated, selective attention, as opposed to a relationship involving either a spatial or a feature representation; although these types of selective attention are not necessarily mutually exclusive. [1]
Selection bias is the bias introduced by the selection of individuals, groups, or data for analysis in such a way that proper randomization is not achieved, thereby failing to ensure that the sample obtained is representative of the population intended to be analyzed. [1] It is sometimes referred to as the selection effect.
Auditory attention is often described as the selection of a channel, message, ear, stimulus, or in the more general phrasing used by Treisman, the "selection between inputs". [8] As audition became the preferred way of examining selective attention, so too did the testing procedures of dichotic listening and shadowing .
In psychology, a lemma (pl.: lemmas or lemmata) is an abstract conceptual form of a word that has been mentally selected prior to the early stages of speech production. This concept is used to explain how the process of generating speech occurs.
