Weighted Least Squares Estimation with Missing Data

Power System State Estimation Using Weighted Least Squares (WLS) and Regularized Weighted Least Squares(RWLS) Method

In this paper, a new formulation for power system state estimation is proposed. The formulation is based on regularized least squares method which uses the principle of Thikonov’s regularization to overcome the limitations of conventional state estimation methods. In this approach, the mathematical unfeasibility which results from the lack of measurements in case of ill-posed problems is elimin...

Boosting Weighted Partial Least Squares for Batch Process Quality Prediction

In batch processes, end-product qualities are cumulatively determined by variable dynamic trajectories throughout each batch. Meanwhile, batch processes are inherently time-varying, implying that process variables may have different impacts on end-qualities at different time intervals. To take both the cumulative and the time-varying effects into better consideration for quality prediction, a b...

Weighted Local Least Squares Imputation Method for Missing Value Estimation

Missing values often exist in the data of gene expression microarray experiments. A number of methods such as the Row Average (RA) method, KNNimpute algorithm and SVDimpute algorithm have been proposed to estimate the missing values. Recently, Kim et al. proposed a Local Least Squares Imputation (LLSI) method for estimating the missing values. In this paper, we propose a Weighted Local Least Sq...

Modified Weighted Least Squares Method to Improve Active Distribution System State Estimation

The development of communications and telecommunications infrastructure, followed by the extension of a new generation of smart distribution grids, has brought real-time control of distribution systems to electrical industry professionals’ attention. Also, the increasing use of distributed generation (DG) resources and the need for participation in the system voltage control, which is possible ...
