Web13 apr. 2024 · All eigenvalues with an index less than q 0, i.e., Q = q 0 − 1, are accepted as low-rank eigenvalues. We used MC simulation to confirm that as the ballistic component increases, the eigenvalues of the ballistic become larger, especially the first few eigenvalues. At the same time, the multiple scatterings always remain very low. WebAbstract This paper considers the problem of identifying multivariate autoregressive (AR) sparse plus low-rank graphical models.
