Practical application – types of university enrolments

In Brazil, one of the ways for a person to enter university is taking an exam and if he/she achieves the minimum grade required for the course that he/she is seeking, then he/she can enroll. To demonstrate the backpropagation algorithm, let us consider this scenario. Data showed in the following table was collected from a university database. The second column represents the person's gender (one means female, and zero means male); the third column has grades scaled by 100, and the last column is formed by two neurons (1,0 means performed enrollment, and 0,1 means waiver enrollment.
