The majority of these algorithms can be applied only to data described by discrete numerical or nominal attributes features. Discover Live Editor Create scripts with code, output, and formatted text in a single executable document. If there is any problemplease let me know.

Could you please send me the data directly? Tags Add Algoritbm classification data mining discretization. Second, the disretization of the intervals is improved based on the data classes distribution, which leads to better classification performance on balanced and, especially, unbalanced data.

Select the China site in Chinese or English for best site performance. Other MathWorks country sites are not optimized for visits from your location. I am not able to understand the class labels assigned to the Yeast dataset.

Supervised discretization is one of basic data preprocessing techniques used in data mining. Guangdi Li Guangdi Li view profile. These data sets are very different in terms of their complexity, number of classes, number of attributes, number of instances, and unbalance ratio discretjzation of size of the majority class to minority class. This code is based on paper: Discretized data sets are available to download for each discretization method.

Hemanth Hemanth view profile. Updates 17 Oct 1. I will answer you as soon as possible. Third, the runtime of the algorithm is lower than CAIM’s. These algorithms were used in Garcia et al. Full results for each discretization and classification algorithm, and for each data set are available to download in CSV format.

Learn About Live Editor. First, it generates more flexible discretization schemes while producing a small number of intervals. Thanks for the code Guangdi Li. One can start with “ControlCenter.

One fold is used for pruning, the rest for growing the rules. The algorithm has been discretizatiln free-parameter and it self-adapts to the problem complexity and the data class distribution. Then I could test it and find the problem. CAIM class-attribute interdependence maximization is designed to discretize continuous data.

The task of extracting knowledge from databases is quite often performed by machine learning algorithms. Yu Li Yu Li view profile. I have a question regarding the class labels. Based on your location, we recommend that you select: In the case of continuous attributes, there is a need for a discretization algorithm that transforms continuous attributes into discrete ones.

The data sets are available to download balanced and unbalanced. 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. Comments and Ratings 4. Attempted to access B 0 ; index must be a positive integer or logical.

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 methods on 28 balanced, and 70 unbalanced data sets.
