Breast cancer is one of the leading causes of mortality among women, and the early diagnosis is of significant clinical importance. In this paper, we describe several linear fusion strategies, in particular the Majority Vote, Simple Average, Weighted Average, and Perceptron Average, which are used to combine a group of component multilayer perceptrons with optimal architecture for the classific...

Many performance metrics have been introduced in the literature for the evaluation of classification performance, each of them with different origins and areas of application. These metrics include accuracy, unweighted accuracy, the area under the ROC curve or the ROC convex hull, the mean absolute error and the Brier score or mean squared error (with its decomposition into refinement and calib...

in this paper, first the available single charting methods, which have been proposed to detect simultaneous shifts in a single process mean and variance, are reviewed. then, by designing proper simulation studies these methods are evaluated in terms of in-control and out-ofcontrol average run length criteria (arl). the results of these simulation experiments show that the ewma and ewms methods ...

We consider estimation of the common probability density f of i.i.d. random variables Xi that are observed with an additive i.i.d. noise. We assume that the unknown density f belongs to a class A of densities whose characteristic function is described by the exponent exp(−α|u|r) as |u| → ∞, where α > 0, r > 0. The noise density is supposed to be known and such that its characteristic function d...

In this paper, an image quality measure, termed pixel-based correlation weighted-mean square error (WMSE), is presented. The proposed distortion measure depends not only on the mean square error in the distorted image, but also on correlation between pixels in a predefined neighborhood. Experimental results are given to show the advantage of the described method.

Learning management systems (LMS, for short) have meanwhile gained an enormous practical relevance. Nevertheless, the quality of service offered is, at least in some respect, astonishingly behind the state of the art. Adaptivity of system behavior is such a field in which we confine ourselves to much less than we can afford. The authors develop an original approach, demonstrate an implementatio...

—In this paper, A new image steganography scheme is proposed which is a kind of spatial domain technique. In order to hide secret data in cover-image, the first component alteration technique is used. Techniques used so far focuses only on the two or four bits of a pixel in a image (at the most five bits at the edge of an image) which results in less peak to signal noise ratio and high root mea...

The application of genome scale RNA interference (RNAi) relies on the development of high quality RNAi high throughput screening (HTS) assays. An important quality control (QC) characteristic in an HTS assay is how well the positive controls, samples, and negative controls can be separated from each other in the assay. Signal-to-noise ratio, signal-to-background ratio, Z-factor and Z’-factor ha...
