Abstract: In this letter, we devise two moving sampling schemes for two-dimensional (2D) direction-of-arrival (DOA) estimation using sparse planar arrays. The proposed schemes are applied to two ...

Sparse Autoencoders (SAEs) have recently gained attention as a means to improve the interpretability and steerability of Large Language Models (LLMs), both of which are essential for AI safety. In ...

Abstract: Electrically large arrays offer high resolution, however since cost is proportional to the number of elements, large dense arrays have a high cost. Sparse arrays on the other hand offer a ...
