Researchers have extended Occam's inversion, a geophysical algorithm, by incorporating lasso fusion and overcomplete dictionaries. This new approach aims to produce sharper models by adapting l1 regularization techniques commonly used in statistics and imaging. The study details mathematical frameworks for three solvers—coordinate descent, iteratively reweighted least squares (IRLS), and split Bregman—and recommends specific solvers for 1D and 2D problems based on performance.
