Abstract
It is known that a high-dimensional sparse vector x* in R^n can be recovered
from low-dimensional measurements y= A^{m*n} x* (m<n) . In this paper, we
investigate the recovering ability of l_p-minimization (0<=p<=1) as p varies,
where l_p-minimization returns a vector with the least l_p ``norm'' among all
the vectors x satisfying Ax=y. Be...More
