Este artículo trata del estado de arte frente al uso de Rough Set en la clasificación de imágenes satelitales, ésta técnica hace parte de un conjunto de algoritmos que se agrupan dentro de lo que se denomina minería de datos. Hasta ahora Rough set se ha aplicado preferencialmente en el descubrimiento de insolvencias en datos obtenidos de manera experimental durante un lapso de tiempo específico, característica que ha llevado a que se implemente con éxito en empresas que requieren tomar decisiones basadas en los análisis de cifras de producción en periodos de tiempo determinados; de este conjunto de algoritmos de minería de datos, muchos se han implementado en la clasificación de imágenes satelitales buscando determinar o bosquejar elementos presentes en la superficie terrestre de acuerdo a su comportamiento frente a la radianza electromagnética y así distinguir patrones dentro de las imágenes. Palabras Clave: Conjuntos Aproximados, Imágenes Satelitales, indiscernibleThis article is about art state in front of The Rough Set use in the satellite images classification, this technique takes part of a set of techniques and algorithms which are grouped in the data mining. Till now Rough set has been applied preferentially in the discovery of information insolvencies obtained in an experimental way during a specific time, this characteristic has let it to be implemented successfully in companies which need to make decisions based on the production numbers analysis in certain periods of time; many of these data mining algorithms set have been implemented in the classification of the satellite images seeking to determine or to draw the elements on the earth surface according to its behaviour towards the electromagnetic radiance and in this way to distinguish patterns inside these images. Keywords: Rough Set, Satellite Images, indiscernible

Purpose Data mining algorithms using electronic health records (EHRs) are useful in large-scale population-wide studies to classify etiology and comorbidities ( Casey et al., 2016 ). Here, we apply this approach to developmental language disorder (DLD), a prevalent communication disorder whose risk factors and epidemiology remain largely undiscovered. Method We first created a reliable system for manually identifying DLD in EHRs based on speech-language pathologist (SLP) diagnostic expertise. We then developed and validated an automated algorithmic procedure, called, Automated Phenotyping Tool for identifying DLD cases in health systems data (APT-DLD), that classifies a DLD status for patients within EHRs on the basis of ICD (International Statistical Classification of Diseases and Related Health Problems) codes. APT-DLD was validated in a discovery sample ( N = 973) using expert SLP manual phenotype coding as a gold-standard comparison and then applied and further validated in a replication sample of N = 13,652 EHRs. Results In the discovery sample, the APT-DLD algorithm correctly classified 98% (concordance) of DLD cases in concordance with manually coded records in the training set, indicating that APT-DLD successfully mimics a comprehensive chart review. The output of APT-DLD was also validated in relation to independently conducted SLP clinician coding in a subset of records, with a positive predictive value of 95% of cases correctly classified as DLD. We also applied APT-DLD to the replication sample, where it achieved a positive predictive value of 90% in relation to SLP clinician classification of DLD. Conclusions APT-DLD is a reliable, valid, and scalable tool for identifying DLD cohorts in EHRs. This new method has promising public health implications for future large-scale epidemiological investigations of DLD and may inform EHR data mining algorithms for other communication disorders.

The achievement of accepting optimal tax need effective and efficient tax supervision can be achieved by classifying taxpayer compliance to tax regulations. Considering this issue, this paper proposes the classification of taxpayer compliance using data mining algorithms; i.e. C4.5, Support Vector Machine, K-Nearest Neighbor, Naive Bayes, and Multilayer Perceptron based on the compliance of taxpayer data. The taxpayer compliance can be classified into four classes, which are (1) formal and material compliant taxpayers, (2) formal compliant taxpayers, (3) material compliant taxpayers, and (4) formal and material non-compliant taxpayers. Furthermore, the results of data mining algorithms are compared by using Fuzzy AHP and TOPSIS to determine the best performance classification based on the criteria of Accuracy, F-Score, and Time required. Selection of the taxpayer's priority for more detailed supervision at each level of taxpayer compliance is ranked using Fuzzy AHP and TOPSIS based on criteria of dataset variables. The results show that C4.5 is the best performance classification and achieves preference value of 0.998; whereas the MLP algorithm results from the lowest preference value of 0.131. Alternative taxpayer A233 is the top priority taxpayer with a preference value of 0.433; whereas alternative taxpayer A051 is the lowest priority taxpayer with a preference value of 0.036.

The Intelligent computing system, described to be a collection of the connected device working in mutual understanding to attain a particular purpose, is an incorporation of artificial intelligence and the computational intelligence, and are employed in variety of applications. The paper presents the survey on the data mining algorithms and the techniques that could be employed with the intelligent computing system, presenting a basic conception of the data mining along with the prominent algorithms of the data mining and the classification of its techniques, further the survey concludes with the challenges included in the overview of the survey done along with the future enhancement in the research that analyses the data mining techniques in the intelligent computing applications.
