One of the most commonly reported malignancy with serious health hazards in the world is oral cancer. In developing countries, the estimated cases of oral cancer are much higher when compared to the developed countries. The easiest way to detect and classify the oral cancer is by means of visual inspection and it is followed by the biopsy procedure. The inspection of oral cancer in a visual manner is not always reliable and it is based mainly on the analysis of clinical features and sometimes during its initial stage it may go unnoticed by highly trained specialists too. Therefore, there is an absolute necessity to screen and classify the oral cancer that should be quite accurate, reliable and with less human manual intervention. Here, in this paper, classification of oral cancer is given prior importance and so Probably Approximate Correct (PAC) Bayesian Classifier is used a first level classifier and then it is further optimized with the Finite Mixture Model (FMM) which is used as a second level classifier. Results show that when PAC Bayesian is used, an average classification accuracy of 96.23% is obtained for all the stages and when it is further optimized with FMM, it gives a classification accuracy of 100%.
