Research on Identification of Key Influencing Factors of Power Grid Investment Demand Based on Data Mining

The influencing factor mining arithmetic ground on gray correlation degree-principal component factor is used to cotton the key affecting factors of power grid introjection demand. The gray correlation degree is used to remove non-critical influencing factors, and the principal component factor is used to shorten the overlap of key influencing factors. And shorten the dimensionality of the input carrier of the prediction model.
