Gaussian conditionally Markov sequences: Dynamic models and representations of reciprocal and other classes

R Rezaie, XR Li - IEEE Transactions on Signal Processing, 2019 - ieeexplore.ieee.org
Conditionally Markov (CM) sequences are powerful mathematical tools for modeling
problems. One class of CM sequences is the reciprocal sequence. In application, we need …

Gaussian conditionally Markov sequences: Modeling and characterization

R Rezaie, XR Li - Automatica, 2021 - Elsevier
The conditionally Markov (CM) sequence is a natural generalization of the Markov sequence

Robust identification of “sparse plus low-rank” graphical models: An optimization approach

V Ciccone, A Ferrante, M Zorzi - 2018 IEEE Conference on …, 2018 - ieeexplore.ieee.org
Motivated by graphical models, we consider the “Sparse Plus Low-rank” decomposition of a
positive definite concentration matrix-the inverse of the covariance matrix. This is a classical …
