Linear System Identification via Atomic Norm Regularization
System identification Atomic norms Hankel operators Optimization
2012/4/18
This paper proposes a new algorithm for linear system identification from noisy measurements. The proposed algorithm balances a data fidelity term with a norm induced by the set of single pole filters...
Atomic norm denoising with applications to line spectral estimation
Atomic norm line spectral estimation Information Theory
2012/4/18
The sub-Nyquist estimation of line spectra is a classical problem in signal processing, but currently popular subspace-based techniques have few guarantees in the presence of noise and rely on a prior...
