Damage detection in the wooden bridge based on the conventional GMM method using 3 different sets of initial parameters. For each set of initial parameters, the initial mean is listed in Tables 5, 6 and 7, the initial weight of each Gaussian component is set as \(\:{\alpha\:}_{k}^{0}=1/9\), the initial covariance matrix of each Gaussian component is set as
