Adaptive Weighted Maximum Margin Criterion [PDF]

2020 IEEE 3rd International Conference on Information Systems and Computer Aided Education (ICISCAE), 2020
Feature extraction is an image processing method widely used in machine learning, playing a significant role in both recognition and classification tasks. In contrast with unsupervised feature learning methods, supervised feature learning methods supported by labels achieve more valuable discriminative information.

Anticipation and the adaptive control of safety margins in driving

Ergonomics, 1999
Driving is a task that requires the timely detection of critical events and relevant changes in traffic circumstances. Adaptation of speed and safety margins allows drivers to control the time available to react to potential hazards. One of the basic safety margins in driving is the time headway preserved with respect to cars ahead.

Wear and marginal adaptation of composite resin inlays

The Journal of Prosthetic Dentistry, 1994
MOD inlays were made with conventional, coarse hybrid, fine hybrid, and two microfilled composite resins. They were adhesively luted in six extracted human molars for each group and were subjected to longitudinal, in vitro testing. Final wear ranged from 46.8 +/- 18.6 microns for fine hybrid composite resin to 132.0 +/- 39.3 microns for conventional ...

An analysis of margin adaptation of all-porcelain facial margin ceramometal crowns

The Journal of Prosthetic Dentistry, 1986
E limination of the metal collar or metal substructure at the facial margin of a ceramometal crown will greatly improve the esthetic result of the completed restoration. A number of techniques for fabrication of facial porcelain margins for these restorations (platinum foil, refractory die, and direct lift-off) have been described.‘-’ The least ...

Adaptation of silicate and Adaptic to the margins of cavities

Journal of Oral Rehabilitation, 1975
SummaryThe effects of etching of the enamel, on the adaptation of silicate and Adaptic to the cavity walls was examined with the scanning electron microscope. Replica methods were utilized to ensure that no shrinkage of the filling materials was caused by the vacuum in the instrument.

Factors influencing the marginal adaptation of amalgam

The Journal of the American Dental Association, 1967
Results of this study indicated that under controlled technics the best adaptations were obtained by using small increments of 50 to 52 percent mercury amalgam mix without expressing mercury, and by use of lateral condensing thrusts.

Marginal adaptation of resin veneers to gold castings

Acta Odontologica Scandinavica, 1985
The magnitude of the fissures between resin facing materials and gold castings was measured by light microscopy. Two different products and two different processing procedures were used. The effect of water sorption on the fissure size was also studied. Mean fissure sizes varied between 3 and 25 microns.
