Timing-related defects are becoming increasingly important in nanometer technology designs. Small delay variations induced by crosstalk, process variations, powersupply noise, as well as resistive opens and shorts can potentially cause timing failures in a design, thereby leading to quality and reliability concerns. We present a testgrading technique to leverage the method of output deviations ...

The network theory of immunology proposes that antigen receptors themselves provide units for selection by antireceptor receptors. This work discusses the implication of receptor-receptor recognition in the context of a previously developed elaborated clonal selection algorithm (ECSA). The result is a pattern recognition-based system capable of cognitive tasks that surpass the simple ECSA, and ...

Feature selection is the process of choosing a subset of features from the original larger set that are related to a certain outcome, such as disease type, dose, income, and time to event. The use of feature selection procedures is almost compulsory and complex in biology and medicine because the generation of massive datasets is nowadays common for many stateof-the-art technologies such as tra...

Selection effects include seemingly independent influences on, and choices in, conducting and reporting primary research that may bias a stock of knowledge. Such effects may arise from sociopolitical influences (research priority selection), researcher choices (methodology selection), peer review influences (publication selection), and metaanalyst choices (metadata sample selection). This paper...

Nowadays, gait is a crucial field for many pattern recognition researchers. It is considered as a good way for biometric authentication in many surveillance systems. In this paper, a new method has been introduced to identify night walker images captured by infrared cameras. This method depends on the silhouette’s presence on different horizontal levels. A new proposed algorithm to select the A...

One of the hot topics discussed recently in relation to pattern recognition techniques is the question of actual performance of modern feature selection methods. Feature selection has been a highly active area of research in recent years due to its potential to improve both the performance and economy of automatic decision systems in various applicational fields, with medical diagnosis being am...

In this paper, the historical evolution of the concept of testor is presented. Testors in a bivalued logic, in a k-valued logic, and also in a fuzzy logic are considered, particular considerations about each case are expressed. This concept evolution is presented to English readers for the "rst time. The authors reviewed this history because testor, in each particular formulation, is an interes...

The so-called logical combinatorial approach to Pattern Recognition is presented, and works (mainly in Spanish and Russian) that are not ordinarily available, are exposed to the Western reader. The use of this approach for supervised and unsupervised pattern recognition, and for feature selection is reviewed. Also, an uni"ed notation describing the original contributions is presented, thus rend...
