In this paper, the authors introduces a new inequalities index, which was inspired from the simple perceptron’s pattern in the Artificial Neural Networks (ANNs) scientific field and nominated by the authors Modulus Perceptron Inequalities Index (MPII). Classification is an important issue in the field of computer science research. There are various methods for classification for complex problems. The level of accuracy depends on complexity of problem. XOR classification is an open problem and there are many approaches to solve it.
