Abstract: Based on Principal Component Analysis and Gene Expression Programming, an optimum GEP algorithm is proposed and applied in the prediction of blasting vibration peak value and main frequency. In this algorithm, PCA method is used to preprocess the input data, the correlation among the inputs is eliminated, and then GEP is applied to construct the prediction model. The experiment results show that this algorithm is more accurate and stable than existing prediction algorithms.
