An experimental comparison of performance measures for classification
Pattern Recognition Letters, 2009Performance metrics in classification are fundamental in assessing the quality of learning methods and learned models. However, many different measures have been defined in the literature with the aim of making better choices in general or for a specific application area. Choices made by one metric are claimed to be different from choices made by other

MEASURING THE PERFORMANCE OF ORDINAL CLASSIFICATION
International Journal of Pattern Recognition and Artificial Intelligence, 2011Ordinal classification is a form of multiclass classification for which there is an inherent order between the classes, but not a meaningful numeric difference between them. The performance of such classifiers is usually assessed by measures appropriate for nominal classes or for regression. Unfortunately, these do not account for the true dimension of

Classification of Visual Performance
Archives of Ophthalmology, 1976To the Editor. —Classification of visual performance has traditionally been according to the simple dichotomy of "legally seeing" vs "legally blind." This oversimplification has ignored the fact that there is another group with unique problems—patients with low vision . They differ from the blind in that they have usable vision.

Bayesian classification and classification performance for independent distributions (Corresp.)
IEEE Transactions on Information Theory, 1981Some general conditions are derived for the mean recognition accuracy of a Bayesian classifier to approach unity as the feature dimensionality increases to infinity.

Independence, Measurement Complexity, and Classification Performance
IEEE Transactions on Systems, Man, and Cybernetics, 1975If f(x) and g(x) are the densities for the N-dimensional measurement vector x, conditioned on the classes c1 and c2, and if finite sets of samples from the two classes are available, then a decision function based on estimates f(x) and ?(x) can be used to classify future observations.

Classification and performance of reconfigurable architectures
1995Recently, several systems have been designed which use reconfigurable logic to perform general purpose computation. While the number of these systems being constructed continues to increase, their relationship to conventional architectures is not clear.

Misregistration Effects On Classification Performance
SPIE Proceedings, 1987An analytical investigation is described which relates errors in spatial registration of multispectral and multitemporal data sets to error in classification. Of particular interest is the classification of large areas of crops. Misregis-tration effects on the statistics of field-center and boundary pixels are studied.

Multilabel Classification Rule with Performance Constraints
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006A formulation for multilabel and performance constraints classification problems is presented within the framework of statistical decision theory. The definition of the problem takes into account three concerns. The first is the cost function which defines the criterion to minimize; the second is the decision options which are defined by the admissible

The Classification Performance of a Three-Product Cyclone
Wireless Personal Communications, 2018Conventional (two products) cyclone have been widely used for classification in most mineral plants. But it is hard to satisfy the requirements of some productions by changing the parameter, such as cylindrical length and cone angle. In this paper, a three-product cyclone was developed and tested for recovery of the solid particles, which was composed ...
