Risk Warning Method of Football Competition Based on Improved Copula Model
A football competition risk intelligent warning method based on an improved Copula model is proposed to address the issues of large errors between warning values and actual values,and multiple false alarms in football matches.Based on the fuzzy comprehensive evaluation matrix,the evaluation system for football competition risk indicators is determined.The indicator level status is classified,the Copula function is selected,and an improved Copula football competition risk intelligent warning method is constructed to accurately judge football competition risks and reduce risk losses.The experimental results show that the interference suppression of this method is high,maintained above 20 dB,and have high anti-interference ability.It can effectively suppress interference.This method also reduces the error between the warning value and the actual value,reduces the number of false alarms in the warning,and verifies the practicality and feasibility of this method.
