USING DATA MINING METHODS TO SOLVE CLASSIFICATION PROBLEMS IN FINANCIAL-BANKING INSTITUTIONS

Data Mining refers to the analysis of large amounts of data stored in computers. The Big Data era is already present, with current sources indicating that more data have been created over the last two years than they have been generated throughout the entire human history. Big Data involves data sets so large that traditional data analysis methods are no longer usable due to the huge amount of data. Lacking or ignoring the data structure is an extremely important aspect, even more important than size, in data analysis, transformation, innovation and value for business. It was said that there are important data about analysis rather than data themselves.
