Group-Utility Metric for Efficient Sensor Selection and Removal in LCMV Beamformers

In sensor arrays or sensor networks, tracking each sensors utility helps in excluding those which do not sufficiently contribute to the task at hand, thereby reducing energy consumption or avoiding model overfitting. In a linearly-constrained minimum variance (LCMV) beamformer, the utility of a sens…
