In this paper, we present a new weighted fuzzy interpolative reasoning method for sparse rule-based systems. The proposed uses increment transformation and ratio techniques to handle in It allows each variable that appears the antecedent parts of rules associate with weight between zero one. Moreover, also propose an algorithm automatically tunes optimal weights variables appearing rules. We apply truck backer-upper control problem. performs better than ones obtained by traditional inference...

Four photoluminescent dye crystals, TPB-n (n = 1–3) and TPCH, have been synthesized in isolation from carbon–carbon coupling of 4,4′-trimethylene-dipyridine (tmdp) the absence organic solvent catalyst via situ one-pot metal/ligand oxidative-dehydrogenation reactions. Large crystals obtained readily separated reaction products without need for purification. Their structures were characterized: TPB TPCH represent two dissimilar oxidized forms tmdp dimers; was less but accompanied with partial...

Abstract Background Genome-wide association studies (GWAS) provide a powerful means to identify associations between genetic variants and phenotypes. However, GWAS techniques for detecting epistasis, the interactions associated with phenotypes, are still limited. We believe that developing an efficient effective method detect epistasis will be key discovering sophisticated pathogenesis, which is especially important complex diseases such as Alzheimer’s disease (AD). Results In this regard,...
