Feature Extraction Method of Electronic Information Based on Statistical Correlation

Since the society enters information age, science and technology have changed with each passing day. Electronic has deeply affected social development people’s life. Based on statistical correlation algorithm, this study analyzes establishment model of algorithm. Then, feature extraction electronic is obtained according to which promotes information., Afterwards, methods among four cities Beijing, Shanghai, Chongqing Tianjin are compared analyzed in detail. The experimental results show that method based can be well applied municipalities directly under central government, provides some theoretical support for our country.
