Abstract: Sparse arrays offer economic advantages by reducing the number of antennas. However, directly utilizing the covariance matrix of sparse array signals for wideband beamforming may lead to the ...

A demo for a video game based on "The Matrix" franchise had AI-powered non-playable characters realize they were code inside a simulation.

Based on these characteristics, an innovative low-rank sparse matrix decomposition (LRSD) method is developed using equivalent matrix gamma norm (EMGN) and equivalent minimax-concave penalty (EMCP) to ...
