The ur-CAIM was compared with 9 well-known discretization methods on 28 balanced, and 70 unbalanced data sets. Comments and Ratings 4.

Updated 17 Oct CAIM class-attribute interdependence maximization is designed to discretize continuous data. In the case of continuous attributes, there is a need for a discretization algorithm that transforms continuous attributes into discrete ones. I will answer you as soon as possible. The results obtained were contrasted through non-parametric statistical tests, which show that our proposal outperforms CAIM and many of the other methods on both types of data but especially on unbalanced data, which is its significant advantage.

Discretized data sets are available to download for each discretization method.

The data sets are available to download balanced and unbalanced. Second, the quality of the intervals is improved based on the data classes distribution, which leads to better classification performance on balanced and, especially, unbalanced data.

Hemanth Hemanth view profile.

However, new arising challenges such as the presence of unbalanced data sets, call for new algorithms capable of handling them, in addition to balanced data.

Supervised discretization is one of basic data preprocessing techniques used in data mining. Updates 17 Oct 1.

These data sets are very different in terms of their complexity, number of classes, number of attributes, number of instances, and unbalance ratio ratio of size of the majority class to minority class.

Hello sir i am student of jntuk university. Thanks for the code Guangdi Li. The algorithm has been designed free-parameter and it self-adapts to the problem complexity and the data class distribution. Could you please send me the data directly? Third, the runtime of the algorithm is lower than CAIM’s.
