A digitally programmable active resistor in CMOS technology

Abstract

Typical testors are a useful tool for both feature selection and for determining feature relevance in supervised classification problems. Nowadays, generating all typical testors of a training matrix is computationally expensive; all reported algorithms have exponential complexity, depending mainly on the number of columns in the training matrix. For this reason, different approaches such as sequential and parallel algorithms, genetic algorithms and hardware implementations techniques have been developed. In this paper, we introduce a fast implementation of the algorithm CT-EXT (which is one of the fastest algorithms reported) based on an accumulative binary tuple, developed for generating all typical testors of a training matrix. The accumulative binary tuple implemented in the CT-EXT algorithm, is a useful way to simplifies the search of feature combinations which fulfill the testor property, because its implementation decreases the number of operations involved in the process of generating all typical testors. In addition, experimental results using the proposed fast implementation of the CT-EXT algorithm and the comparison with other state of the art algorithms that generated typical testors are presented.

Munoz-Valle, J.F.",,"2009",,"Systemic lupus erythematosus in some cases is characterized for development of thrombotic events with a significantly increased risk of mortality. The frequencies and clinical associations of Ser413/Cys413 PAI-2 polymorphism in 40 systemic lupus erythematosus, 50 rheumatoid arthritis patients, and 100 healthy subjects were investigated. The Ser 413/Ser413 genotype frequency was 53% (lupus), 36% (rheumatoid arthritis), and 35% (healthy subjects). The Ser413 allele was associated with systemic lupus erythematosus (P =.04, odds ratio = 1.76, 95% confidence interval = 1.01-3.06). In all, 4 patient carriers of Ser 413/Ser413 genotype, developed thrombotic events. The lupus patients identified with Ser413/Ser413 genotype showed an increased damage (57%), compared with Ser413/Cys 413 and Cys413/Cys413 genotypes, with significant difference (P =.03). These findings suggest an association of Ser413 /Ser413 genotype with greater damage index score and Ser413 allele with systemic lupus erythematosus. Besides, PAI-2 polymorphism could be related with thrombotic phenomena in systemic lupus erythematosus.",,,,,,"10.1177/1076029607308868",,,"http://hdl.handle.net/20.500.12104/38986","http://www.scopus.com/inward/record.url?eid=2-s2.0-64549131747&partnerID=40&md5=608df4c662c9b122892d92b7e4322c0d
