“…Model complexity in pDMDc for metabotyping, i.e., the choice of and (for simplicity we choose ), was assessed by identifying the inflection point in the scree plot of the singular values derived from the SVD = ( 28 , 29 ). Further, we classified the most dominant dynamical profile by clustering the covariance matrix of the measured data for each metabolite averaged over all individuals and diets ( Equations 23, 24 ).…”

“…The dynamic system’s nonlinear behavior can result in non-classical damping, observed not only in building structures but also in air and spacecraft structures under various loading conditions [ 11 ]. To tackle nonlinear identification, linear models such as the eigenvalue realization algorithm (ERA) have proven to be effective [ 12 , 13 ].…”

“…The Bayesian operational modal analysis (BAYOMA) method operating in the frequency domain and applicable for close modes has recently been developed based on an expectation-maximization algorithm that shows promise for simpler algorithm and computer coding [ 13 ]. Recent developments in the field of operational modal analysis (OMA) and blind source separation (BSS) have attracted considerable interest in separating modal response and estimating dynamic properties [ 6 , 14 , 15 , 16 ].…”
