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.

The task of extracting knowledge from databases is quite often performed by machine learning algorithms. In the case of continuous attributes, there is a need discretizatlon a discretization algorithm that transforms continuous attributes into discrete ones. The majority of these algorithms can be applied only to discreetization described by discrete numerical or nominal attributes features. 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.

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

Attempted to access B 0 ; discretizatlon must be a positive integer or logical. One can start with “ControlCenter. One fold is used for pruning, the rest for growing the rules. Select a Web Site Choose a web site to get translated content where available and see local events and offers.

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.

Guangdi Li Guangdi Li view profile. Third, the runtime of the alglrithm is lower than CAIM’s. Hemanth Hemanth view profile. CAIM class-attribute interdependence maximization is designed to discretize continuous data. Other MathWorks country sites are not optimized for visits from your location. Updated 17 Oct I have a question regarding the class labels. The ur-CAIM was compared with 9 well-known discretization methods on 28 balanced, and 70 unbalanced data sets.

I will answer you as soon as possible. First, it generates more flexible discretization schemes while producing a small number of intervals.
