First, it generates more flexible discretization schemes while producing a small number of intervals.

ur-CAIM: Improved CAIM Discretization for Unbalanced and Balanced Data
In the case of continuous attributes, there is a need for a discretization algorithm that transforms continuous attributes into altorithm ones.
Discover Live Editor Create scripts with code, output, and formatted text in a single executable document. Updated 17 Oct Comments and Ratings 4. Other MathWorks country ddiscretization are not optimized for visits from your location.
Guangdi Li Guangdi Li view profile. Select the China site in Chinese or English for best site performance. The task of extracting knowledge from databases is quite often performed by machine learning algorithms.
Full results for each discretization and classification algorithm, and for algprithm data set are available to download in CSV format.
The algorithm has been designed free-parameter and it self-adapts to the problem complexity and the data class distribution. Third, the runtime of the algorithm is lower than CAIM’s. Choose a web site to get translated content where available and see local events and offers.
If there is any problemplease let me know. Second, the quality of the intervals disvretization improved based on the data classes distribution, which leads to better classification performance on balanced and, especially, unbalanced data.
Thanks for the code Guangdi Li. The majority of these algorithms can be discrehization only to data described by discrete numerical or nominal attributes features. Then I could test it and find the problem.
CAIM Discretization Algorithm – File Exchange – MATLAB Central
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.
One can start with “ControlCenter. Tags Add Tags classification data mining discretization. Supervised discretization is one of basic data preprocessing techniques used in data mining. Updates 17 Oct 1. CAIM class-attribute interdependence maximization is designed to discretize continuous data. Yu Li Yu Li view profile. You are now following this Submission You will see updates in your activity feed You may receive emails, depending on your notification preferences.
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.
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 ur-CAIM was compared with 9 well-known discretization methods on 28 balanced, and 70 unbalanced data sets. Based on your location, we recommend that you select: Attempted to access B 0 ; index must be a positive integer or logical.
This code is based on paper: I will answer you as soon as possible. I have a question regarding the class labels. Hello sir i am student of jntuk university. Could you please send me the data directly? Discretized data sets are available to download for each discretization method. I am not able to understand the class labels assigned to the Yeast dataset.
