WebDiscretization is the process of transforming numeric variables into nominal variables called bin. The created variables are nominal but are ordered (which is a concept that you will not find in true nominal variable) and algorithms can exploit this ordering information. WebAbstract. Data mining has been widely used in medical and health care domain as the predictive models. Data preprocessing is one of the important steps in data mining process as it consumes about sixty percent of the data mining project effort. Data discretization is one of the pre-...
