Nonasymptotic Performance Analysis of Direct-Augmentation and Spatial-Smoothing ESPRIT for Localization of More Sources Than Sensors Using Sparse Arrays

no code implementations22 Feb 2023 Zai Yang, Kaijie Wang

Direction augmentation (DA) and spatial smoothing (SS), followed by a subspace method such as ESPRIT or MUSIC, are two simple and successful approaches that enable localization of more uncorrelated sources than sensors with a proper sparse array.

Deep Kernel Learning via Random Fourier Features

no code implementations7 Oct 2019 Jiaxuan Xie, Fanghui Liu, Kaijie Wang, Xiaolin Huang

On small datasets (less than 1000 samples), for which deep learning is generally not suitable due to overfitting, our method achieves superior performance compared to advanced kernel methods.
