عنوان مقاله فارسی: میزان همگرایی الگوریتم FOCUSS عنوان مقاله لاتین: Rate of Convergence of the FOCUSS Algorithm نویسندگان: Kan Xie; Zhaoshui He; Andrzej Cichocki; Xiaozhao Fang تعداد صفحات: 13 سال انتشار: 2017 زبان: لاتین Abstract: Focal underdetermined system solver (FOCUSS) is a powerful method for basis selection and sparse representation, where it employs the ℓ p -norm with p ∈ (0, 2) to measure the sparsity of solutions. In this paper, we give a systematical analysis on the rate of convergence of the FOCUSS algorithm with respect to p ∈ (0, 2). We prove that the FOCUSS algorithm converges superlinearly for 0 <; p <; 1 and linearly for 1 ≤
