In this paper, we proposed context-based probability neural network (CPNN) classifiers for solving a medical decision making problems. The concept of “contexts” coming from the clustering research area is explored here to construct the second layer of probability neural network classifiers. Furthermore, genetic algorithm is used to optimize the structure parameters when designing the proposed CPNN. In contrast to the known probability neural networks, the proposed CPNN archive a better accuracy classification rate. Several known data sets are utilized to evaluate the performance of CPNN. Experimental results demonstrate that the relationship between the selected features and disease are more apparent in comparison with the conventional neural network models.
