Discretization leads the improvement in classification accuracy and generalizes the problem well for further knowledge extraction. As a result researchers have developed various discretization methods for preprocessing the data. This paper provides a survey of existing discretization methods that preprocess the data for datamining. Also the paper evaluates the effectiveness of various discretization methods in terms of better discretization scheme and better accuracy of classification by comparing the performance of some traditional and recent discetization algorithms on six different real datasets namely Iris, Ionosphere, Waveform-5000, Wisconsin breast cancer, Hepatitis Domain and Pima Indian Diabetes. The feedforward neural network with conjugate gradient training algorithm is used to compute the accuracy of classification from the data discretized by those algorithms.
