Abstract: Sparse arrays offer a promising solution for reducing the data volume required to reconstruct ultrasound images, making them well-suited for portable and wireless devices. However, the ...

In vision-language models (VLMs), visual tokens usually consume a significant amount of computational overhead, despite their sparser information density compared to text tokens. To address this, ...

Abstract: In this paper, a comprehensive review is carried out of existing sparse arrays for direction-of-arrival (DOA) estimation of non-circular sources. We know that for DOA estimation of ...
