The concept of a preattentive feature has been central to vision and attention research for about half a century. A preattentive feature is a feature that guides attention in visual search and that cannot be decomposed into simpler features. While that definition seems straightforward, there is no simple diagnostic test that infallibly identifies a preattentive feature. This paper briefly reviews the criteria that have been proposed and illustrates some of the difficulties of definition.

Preattentive visual features such as hue or flickering can effectively draw attention to an object of interest - for instance, an important feature in a scientific visualization. These features appear...
Interaction with the environment requires fast and reliable sensory processing. The visual system is confronted with a continuous flow of high-dimensional input (e.g. orientation, color, motion). From...
Feature selection is commonly used as a preprocessing step to machine learning for improving learning performance, lowering computational complexity and facilitating model interpretation. This paper p...
Feature relationships are complex and may contain important information. k top scoring pairs (k-TSP) studies feature relationships by the horizontal comparison. This study examines feature relationshi...
Feature learning and selection have been widely applied in many research areas because of their good performance and lower complexity. Traditional methods usually treat all terms with same feature set...
The purpose of this trial is to assess device performance against participants in an overnight study to ensure the product meets user and clinical requirements
Goal of this study is to determine the benefit of an improved feature on a new hearing aid platform. To investigate the improvements of this feature is compared on a new and older hearing...
A single visit & single arm study in 80 subjects with diabetes to determine if a short educational experience with a new blood glucose meter feature improves the ability of each subject to...
The purpose of this study is to evaluate the performance of a new sensor-based diagnostic feature, which has been implemented in a cardiac resynchronization therapy (CRT) device. This tria...
The purpose of this study is to evaluate the efficacy of the VIP™ feature (available in dual chamber Victory® devices) to reduce unnecessary RV pacing, and to determine if patients with ...
Involuntary shock-like contractions, irregular in rhythm and amplitude, followed by relaxation, of a muscle or a group of muscles. This condition may be a feature of some CENTRAL NERVOUS SYSTEM DISEASES; (e.g., EPILEPSY, MYOCLONIC). Nocturnal myoclonus is the principal feature of the NOCTURNAL MYOCLONUS SYNDROME. (From Adams et al., Principles of Neurology, 6th ed, pp102-3).
An inborn error of carbohydrate metabolism manifesting as a genetic multisystem disorder of autosomal recessive inheritance. A predominant feature is severe central and peripheral nervous system involvement resulting in psychomotor retardation, seizures, cerebellar ataxia, and other symptoms which include growth retardation, retinitis pigmentosa, hypothyroidism, and fatty liver. The notable biochemical feature is the deficiency of a large number of blood glycoproteins and decreased activities of various blood coagulation factors.
Congenital, complete or partial fusion of the TARSAL BONES of the foot. PES PLANUS is usually a feature.
A suborder of the order ARTIODACTYLA whose members have the distinguishing feature of a four-chambered stomach, including the capacious RUMEN. Horns or antlers are usually present, at least in males.
A superorder of CEPHALOPODS comprised of squid, cuttlefish, and their relatives. Their distinguishing feature is the modification of their fourth pair of arms into tentacles, resulting in 10 limbs.
