The task of extracting knowledge from databases is quite often performed by machine learning algorithms. Aren’t the class label supposed to be a binary indicator matrix with 1ofK coding? The ur-CAIM was compared with 9 well-known discretization algoruthm on 28 balanced, and 70 unbalanced data sets. Full results for each discretization and classification algorithm, and for each data set are available to download in CSV format.

Updates 17 Oct 1. These algorithms were used in Garcia et al. Updated 17 Oct I have a question regarding the class labels. Hi, I got a error, can u help me? 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 results obtained were contrasted through non-parametric statistical tests, which show that our proposal outperforms CAIM and many of the other methods on both acim of data but especially on unbalanced data, which is its significant advantage.

In the case of continuous attributes, there is a need for a discretization algorithm that transforms continuous attributes into discrete ones.

CAIM class-attribute interdependence maximization is designed to discregization continuous data.

Based on your location, we recommend that you select: The majority of these algorithms can be applied only to data described by discrete numerical or nominal attributes features. Could you please send me the data directly?

ur-CAIM: Improved CAIM Discretization for Unbalanced and Balanced Data

One fold is used for pruning, the rest for growing the rules. 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. Then I could test it and find the problem. Choose a web site to get translated content where available and see local events and offers. First, it generates more flexible discretization schemes while producing a small number of intervals.

One can start with “ControlCenter.

The algorithm has been designed free-parameter and it self-adapts to the problem complexity and the data class distribution. I am not able to understand the class labels assigned to the Yeast dataset. Yu Li Yu Li view disxretization. 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.
