Abstract

Conventional model-based algorithms are based on building the forward model and then minimizing the cost function with some constrain. In this study, a new approach is proposed, based on building the forward model, stabilizing it and then minimizing the cost function. The more stable system provides more stable solution. A small perturbation in the measurement matrix would not change the solution much if the proposed method is applied.
