Abstract: In this paper, we formulate an efficient progressive version of 3-D SAFT by exploiting the block Toeplitz structure of the matrix unfolding of the underlying tensor. This reduces the ...
Low-Complexity Vector-by-Vector Detector for AFDM-IM Systems by Reconstructing Sparse Channel Matrix
Abstract: In this letter, a low-complexity vector-by-vector aided expectation propagation (VV-EP) detector is proposed for affine frequency division multiplexing (AFDM) with index modulation (IM) ...
When I first wrote “Vector databases: Shiny object syndrome and the case of a missing unicorn” in March 2024, the industry was awash in hype. Vector databases were positioned as the next big thing — a ...
Even before its full science operations have begun, the Vera C. Rubin Observatory in Chile has already helped astronomers find something remarkable. The observatory's first images, revealed in June, ...
AI search startup Perplexity has signed a multi-year licensing deal with Getty Images, which gives it permission to display images from Getty across its AI-powered search and discovery tools. The deal ...
