Abstract:
This paper presents three different types of normalization methods. Normalization is particularly useful for classification algorithm. Each normalization method is tested against the C4.5 algorithm methodology using the data sets with accuracy, tree growing time and number of leaf nodes. In this paper, min-max normalization, z-score normalization and normalization by decimal scaling normalization are compared among large amount of data set. From this comparison, the best normalization method is chosen.
