Football competition risk early warning method based on improved Copula model

Aiming at the problems of large error between the warning value and the actual value and many false alarms in football matches, an intelligent warning method for football match risk based on the improved Copula model is proposed. The football match risk index evaluation system is determined based on the fuzzy comprehensive evaluation matrix, the index level state is divided, the Copula function is selected, and the improved Copula football match risk intelligent warning method is constructed to accurately judge the football match risk and reduce the risk loss. The experimental results show that the interference suppression of this method is maintained above 20 dB, and the interference suppression ratios of the existing methods are only 12.25 dB and 10.58 dB respectively. This method has high anti-interference ability and can effectively suppress interference. This method reduces the error between the warning value and the actual value, reduces the number of false alarms, and is practical and feasible.
