DOI: 10.1002/ecy.2469
Abstract: Eigenvector-mapping methods such as Moran's eigenvector maps (MEM) are derived from a spatial weighting matrix (SWM) that describes the relations among a set of sampled sites. The specification of the SWM is a crucial step,… read more here.

DOI: 10.1016/j.asr.2017.01.030
Abstract: Abstract VTL (Vector Tracking Loop) has a better tracking performance in sensitivity, dynamic, usability and reacquisition, but it is less robust due to its dependence of all channels and also may result in tracking deviation.… read more here.

DOI: 10.1016/j.regsciurbeco.2017.08.005
Abstract: The weighting matrix is a key element in the specification of a spatial model. Typically, this matrix is fixed a priori by the researcher, which is not always satisfactory. Theoretical justification for the chosen matrix… read more here.

DOI: 10.1109/tac.2021.3124193
Abstract: We study autocovariance least squares (ALS) estimation methods for covariance estimation for linear time-invariant systems. Previous works have posited that calculation of the ALS weighting matrix is intractable unless the number of data points $N_d$… read more here.
