caij 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. I am not able to understand the class labels assigned to the Yeast dataset.

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. I have a question regarding the algodithm labels. Hemanth Hemanth 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 ratio of size of the majority class to minority class.

Thanks for the code Guangdi Li. Updated 17 Oct 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. Updates 17 Oct 1. Other MathWorks country sites are not optimized for visits from your location. The results disccretization 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 disceetization on unbalanced data, which is its significant advantage.

The task of extracting knowledge from databases is quite often performed by machine learning algorithms.
