Hemanth Hemanth view profile. First, it generates more flexible discretization schemes while producing a small number of intervals. One fold is used for pruning, the rest for growing the rules.
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. Updated 17 Oct Discover Live Editor Create scripts with code, output, and formatted text in a single executable document.

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.
Guangdi Li Guangdi Li view profile. 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.

This code is based on paper: I have a question regarding the class labels.
ur-CAIM: An Improved CAIM Discretization Algorithm for Unbalanced and Balanced Data Sets
Learn About Live Editor. Discretized data sets are available to download for each discretization method. 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.

The task of extracting knowledge from databases is quite often performed by machine learning algorithms. You are now following this Submission You will see updates alforithm your activity feed You may receive emails, depending on your notification preferences.
Attempted to access B 0 ; index must be a positive integer or logical. Then I could test it and find the problem. I will answer caimm as soon as possible.
Could you please send me the data directly? Choose a web site to get translated content where available and see local events and offers. These data sets are very different in terms of their complexity, number of classes, number discretizatlon attributes, number of instances, and unbalance ratio ratio of size of the majority class to minority class.
I am not able to understand the class labels assigned to the Yeast dataset. Other MathWorks country sites are not optimized for visits from your location. Hello sir i am student of jntuk university.
ur-CAIM: Improved CAIM Discretization for Unbalanced and Balanced Data
Supervised discretization is one of basic data preprocessing techniques used in data mining. Yu Li Yu Li view profile. The ur-CAIM was compared with 9 well-known discretization methods on 28 balanced, and 70 unbalanced data sets. The algorithm has been designed free-parameter and it self-adapts to the problem complexity and the data class distribution.
