Aren’t the class label supposed to be a binary indicator matrix with 1ofK coding? Select the China site in Chinese or English for best site performance. One fold is used for pruning, the rest for growing the rules. Yu Li Yu Li view profile. First, it generates more flexible alggorithm schemes while producing a small number of intervals. I am not able to understand the class labels assigned to the Yeast dataset.

Full results for each discretization and classification algorithm, discretizatioh for each data set are available to download in CSV format. In the case of continuous attributes, there is a need for a discretization algorithm that transforms continuous attributes into discrete ones.

You are now following this Submission You will see updates in your activity feed You may receive emails, depending on your notification preferences. These algorithms were used in Garcia et al. Guangdi Li Guangdi Li view profile. Then I could test it and find the problem.

Updated 17 Oct Choose a web site to get translated content where available and see local events and offers. Supervised discretization is one of basic data preprocessing techniques used in data mining.

The ur-CAIM was compared with 9 well-known discretization methods on 28 balanced, and 70 unbalanced data sets. The data sets are available to download balanced and unbalanced. Hemanth Hemanth view profile. I have a question regarding the class labels.

ur-CAIM: An Improved CAIM Discretization Algorithm for Unbalanced and Balanced Data Sets

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. Third, the runtime of the algorithm is lower than CAIM’s.

Hi, I got a error, can u help me? The majority of these algorithms can be applied only to data described by discrete numerical or nominal attributes features. 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.

CAIM class-attribute interdependence maximization is designed to discretize continuous data. Thanks for the code Guangdi Li. Discover Live Editor Create scripts with code, output, and formatted text in a single executable document.

CAIM Discretization Algorithm – File Exchange – MATLAB Central

This code is based on discretuzation Updates 17 Oct 1. 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. The algorithm has been designed free-parameter and it self-adapts to the problem complexity and the data class distribution.
