In an imbalanced dataset, the positive and negative classes can be quite different in both size and distribution. This degrades the performance of many feature extraction methods and classifiers. This paper proposes a method for extracting minimum positive and maximum negative features (in terms of absolute value) for imbalanced binary classification. This paper develops two models to yield the...

Laminar mixed convection of Aluminium oxide (Al2O3)–water nanofluid flow in an inclined annulus using a single-phase approach was numerically studied. Constant heat flux boundary conditions were applied on the inner and outer walls. All the thermophysical properties of nanofluid, such as, viscosity, heat capacity, thermal conductivity, and thermal expansion coefficient, except density in the bo...

Aim of the study was to evaluate the importance of the combined use of fine needle aspiration cytology (FNAC) and cell-block in the diagnosis of different breast lesions. Patient and methods: This study was a prospective study of 310 cases (301 females and 9 males) with breast swelling, coming to cytopathology unit, faculty of medicine, Zagazig University. FNAC and cell-block were performed. Cy...

Literature addressing master production scheduling (MPS) typically focuses on the development of sophisticated MPS methods with the expectation that these methods will result in feasible plans and improved performance. However, empirical evidence showing that sophisticated methods are better than simpler ones remains scarce, and companies have reported difficulties with using sophisticated plan...

We deal with the problem of preserving various versions of completeness in (< κ)–support iterations of forcing notions, generalizing the case " S–complete proper is preserved by CS iterations for a stationary co-stationary S ⊆ ω 1 ". We give applications to Uniformization and the Whitehead problem. In particular, for a strongly inaccessible cardinal κ and a stationary set S ⊆ κ with fat complem...

The specific electric conductivity of molten HgI2-HgBr2 and Hgl2-Sbl3 binary mixtures was measured as a function of composition and temperature in the ranges 220 — 540 °C and 180 to 540 °C, respectively. In the HgI2-HgBr2 system negative deviations from additivity are found in mixtures rich in HgBr2, and positive ones in those rich in Hgl2 . The positive deviations are more pronounced at higher...

A gastric juice-based PCR assay was compared with culture, microscopy, and a rapid urease test with specimens from 114 subjects. The PCR and conventional tests were positive for 76 and 62% of the subjects, respectively. The prevalence of gastroduodenal disease and seropositivity for anti-Helicobacter pylori immunoglobulin G were similarly high among conventional-test-positive and PCR-only-posit...

A model for learning in the limit is defined where a (so-called iterative) learner gets all positive examples from the target language, tests every new conjecture with a teacher (oracle) if it is a subset of the target language (and if it is not, then it receives a negative counterexample), and uses only limited long-term memory (incorporated in conjectures). Three variants of this model are co...

This study explores post-recovery satisfaction and post-purchase intentions with service recovery of online shopping customers from the perspectives on perceived justice and emotions based on twenty scenarios that combine five service failures and four recoveries. Analytical results indicating that in addition to enhancing post-purchase intentions and post-recovery satisfaction among customers,...
