Optimal Weight and Parameter Estimation of Multi-structure and Unequal-Precision Data Fusion

Measured data fusion process is an effective way to improve the data process precision. In this paper, the fusion weight is firstly introduced, and then we study the optimal weight and parameter estimation using multistructure and unequal-precision data fusion. For the linear regression model, it is theoretically proved that the optimal weight is only related to the data measure precision, which i...
