This article presents two classifiers based on machine learning methods, aiming to detect physiologic anomalies considering Poincaré plots of heart rate variability. It was developed a preprocessing procedure to encoding the plots, based on the Cellular Features Extraction Method. Simulation of different classifiers, artificial neural networks and support vector machine, has been performed and the...
Feature selection continues to grow in importance in many areas of science and engineering, as large datasets become increasingly common. In particular, bioscience and medical datasets routinely contain several thousands of features. For effective data mining in such datasets, tools are required that can reliably distinguish the most relevant features. The latter is a useful goal in itself (e.g. such...
Although there are many studies on computer-aided drug design in recent years, determination of proteins for drug candidates is a remarkable area for research. The first major shortcoming of this kind of problems is the feature selection representing the protein structure best, the former one is the computational complexity. We use three datasets with different sizes such as Cherkasov dataset with...
Machine Learning techniques are successfully applied to establish quantitative relations between chemical structure and biological activity (QSAR), i.e. classify compounds as active or inactive with respect to a specific target biological system. This paper presents a comparison of artificial neural networks (ANN), support vector machines (SVM), and decision trees (DT) in an effort to identify potentiators...
There are striking disparities in the prevalence of dental disease by income. Poor children suffer twice as much dental caries as their more affluent peers, but are less likely to receive treatment. This paper presents an experimental study of the application of machine learning methods to the problem of caries prediction. For this paper a data set collected from interviews with children under five...
Thalassemia is a genetic defect that is commonly found in many parts of the world. Number of humans that are suffering from this disease is determined by screening the heterozygous population. This article investigates the thalassemia screening problem using the unconstrained functional networks classifier. The learning algorithm for this new scheme is briefly illustrated. The new intelligent system...
