These classifiers are combined to produce the final prediction. However, when considering a number of classifiers in the pool, the selection of combination rule is not easy to understand. The aim of this paper is to investigate the performance of different combination rules, including several single classifiers involved in the ensemble. We use various performance metrics and validation tests to assess the performance of these classifiers using a real-world dataset. Finally, among the classifiers we evaluate their performance differences using statistical significant test. The experimental results indicate that combination rule with average voting scheme is the best performer compared with other combination rules and single classifiers in the ensemble.","PeriodicalId":193362,"journal":{"name":"Int.

This research aims to classify mammogram images into three classes, i.e. normal, benign and malignant based on texture features. Some pre-processing techniques were involved, including removing the artefacts, cropping breast area, contrast enhancement and smoothing with median filter. Afterwards, some texture features were extracted followed by classification process by using multi-layer perceptron (MLP) classifier. Classification of normal and abnormal successfully achieved an accuracy of 98.33%, sensitivity of 100% and specificity of 97.5%. Whereas, for classification of three classes (normal, benign and malignant) achieved an accuracy of 90%, sensitivity of 85% and specificity of 87.5%.","PeriodicalId":193362,"journal":{"name":"Int. J.

The adaptive neuro-fuzzy inference system (ANFIS) implementation was used for screening and LBC techniques for confirmation of the ANFIS outcomes. The classification performance of ANFIS model had 98.7% precision with a training error of 1.1652 and basic testing error 1.255. LBC showed eight cases of CL (15.4%) from 259 prostitutes and was age and duration of commercial sex-dependent (P < 0.05). The present ANFIS implemented model is excellent for routine screening of the CSWs, while LBC remains a gold standard for CL diagnosis worldwide.","PeriodicalId":193362,"journal":{"name":"Int. J.

The evaluation outcomes, in terms used in patient's descriptive history in both of the MEDSCAPE and PubMed case studies, showed that the recall amount of system-oriented evaluation was about 90% provided that just top ten results were considered.

In this study, the mechanical analysis and finite element analysis (FEA) of the oculomotor system was based on clinical MRI data and applied to examine the physiological hypotheses of extra-ocular muscle obliquity and deformation respectively. Our mechanical analysis indicated that the muscular obliquity is not the dominated cause of high myopic strabismus. Next, by simulating the effect of different forces applied to the cross section of each extra-ocular rectus muscles, the corresponding eyeball rotations were quantified on normal eyes, and high myopic eyes with and without strabismus. The model suggests that the limitation of rotation in high myopic strabismic eyes is mainly caused by the extra-ocular muscle deformation instead of, but related with, its obliquity, providing a better understanding of the aetiology of high myopic strabismus. To the best of our knowledge, this is the first mechanical and FEA model developed from clinical data to investigate the aetiology of high myopic strabismus, providing important tools for future studies.","PeriodicalId":193362,"journal":{"name":"Int.

EEG is the recording of electrical activity in brain. Careful analysis of these recordings can provide valuable information and understanding the mechanisms of several brain disorder diseases such as epilepsy. Since epileptic seizures occur irregularly and unpredictably, automatic seizure detection in EEG recordings is highly required. We have used discrete wavelet transform (DWT) technique for extraction of potential features from the signal. For classification of these signals into two classes, we have trained the RBFN by a modified version of ABC algorithm (MABC). In this work, we realise, this two class classification problem is highly imbalanced i.e., the instances in one class known as majority class outnumber the instances of other class called the minority class. The SMOTE is first applied to generate synthetic instances in the positive class to balance the training data set. Using the resulting balanced dataset, the MABC optimised RBF network is then constructed to identify the epileptic seizure.","PeriodicalId":193362,"journal":{"name":"Int. J. Medical Eng.

Numerical solver on the forward problem in 3D is used for computing electric potential measured on body surface. Varied spinal BMD are simulated by varying bone relative permittivity and conductivity values which represent different disease stages.
