Nuisance attribute projection (NAP) was an effective method to reduce session variability in SVM-based speaker verification systems. As the expanded feature space of nonlinear kernels is usually high or infinite dimensional, it is difficult to find nuisance directions via conventional eigenvalue analysis and to do projection directly in the feature space. In this paper, two different approaches...

We illustrate with two simple examples how Interactive Evolutionary Computation (IEC) can be applied to Exploratory Data Analysis (EDA). IEC is particularly valuable in an EDA context because the objective function is by definition either unknown a priori or difficult to formalize. The first example involves what is probably the simplest possible transformation of data: linear projections. Whil...

A relative approach degree method of grey relation projection is presented to deal with multiple attribute making in which the attribute weight is unknown and attribute value is hybrid index. firstly, the normalized method of different type indices and the formula of distance for the same type indices are defined, and a objective weights determination model based on hybrid index type is constru...

Influenza infection manifests in a wide spectrum of severity, including symptomless pathogen carriers. We conducted a systematic review and meta-analysis of 55 studies to elucidate the proportional representation of these asymptomatic infected persons. We observed extensive heterogeneity among these studies. The prevalence of asymptomatic carriage (total absence of symptoms) ranged from 5.2% to...

Recently, there have been increasing interests in inferring mirco-expression from facial image sequences. Due to subtle facial movement of micro-expressions, feature extraction has become an important and critical issue for spontaneous facial micro-expression recognition. Recent works used spatiotemporal local binary pattern (STLBP) for micro-expression recognition and considered dynamic textur...

In this study, wave solutions of the (3+1) dimensional Jimbo-Miwa equation and two different phenomena solution, fusion fission, are obtained using modified exponential functionmethod. order to get more possible solutions, cases investigated due nature function method. When resulting analyzed, trigonometric, hyperbolic rational functions obtained. It was checked whether solution found by Wolfra...
