A General Framework for Constraint Minimization for the Inversion of Electromagnetic Measurements (2004, methodology): “This new approach of choosing the regularization parameter is inspired by the work of [12, 13] on the multiplicative regularization for gradient-type algorithm.”
Multiplicative regularization for contrast profile inversion (2003, result): “Instead of taking the previous iterate of the contrast as done in our previous papers [van den Berg et al., 1999] and [van den Berg and Abubakar, 2001], we now take the analytic value of (15) as starting value.”
Microwave Imaging Within the First-Order Born Approximation by Means of the Contrast-Field Bayesian Compressive Sensing (2012, methodology): “Global optimization tools [37], [38], multi-step information retrieval techniques [39], [40] as well as alternative problem formulations such as contrast-source [17], [19] and qualitative methods [25], [26] have been introduced as suitable countermeasures for mitigating the non-linearity or its effe”
