Abstract

Probably approximately correct (PAC) learnability of classification models is crucial in machine learning. Many classification algorithms were introduced and simply validated on benchmark data. And they were not further discussed on under what condition they are assured to be learned successfully, because it is commonly hard to address such PAC learning issues. As one may accept, it would be even crucial to investigate the PAC learnability of the classification models if they are exploited to deal with some special data, such as gene microarray data. Rough hypercuboid classifier (RHC) is a novel classifier introduced for classification based on gene microarray data. After analyzing the VC-dimension and the time complexity of RHC, this paper proved that RHC is a PAC-learning model. The proof gives support to the further RHC applications in classifying cancers based on gene microarray data.
