Abstract :
This paper proposes the concept of function correlation, which takes the concept of linear correlation and concept of non-linear correlation together with a unified. On this basis, a BP neural network model was constructed to approximate the correlation function. Experimental results show that the correlation function determined by BP neural network can be a higher correlation coefficient.
