Este trabajo de investigación presenta el desarrollo un modelo utilizando técnicas minería datos para identificar variables financieras en una empresa manufacturera carrocerías vehículos automotores Pereira. El estudio se estructura cuatro fases claves. La primera fase centra preprocesamiento datos, incluyendo la caracterización, normalización, y reducción dimensionalidad mediante PCA, Relief Correlación. segunda aplica aprendizaje no supervisado con K-means Mezclas Gaussianas (GMM) agrupar...
The recurrent use of databases with categorical variables in different applications demands new alternatives to identify relevant patterns. Classification is an interesting approach for the recognition this type data. However, there are a few amount methods purpose literature. Also, those techniques specifically focused only on kernels, having accuracy problems and high computational cost. For reason, we propose identification using conventional classifiers (LDC-QDC-KNN-SVM) mapping increase...
The education is a fundamental law that promotes the social and economic development of nation. Also, it how country can achieve its sustainable objectives. Because this, various international organizations (Unicef-UNESCO- Banco Mundial -OECD) are promoting coverage in underdeveloped countries. On other hand, projects such as PISA aim to carry out annual evaluations more than 30 countries serve reference educational level encourages nations improve quality education. Therefore, objective...
