Toward Practical and Reliable Electromagnetic Inversion: A Semi-Stochastic Lévy Gradient Descent Approach With Trajectory-Based Model Assessment

Quantitative assessment of inverted models has long been a major challenge in geophysical inversion, particularly in 3-D electromagnetic (EM) inversion. Traditional gradient-based inversion methods are computationally efficient, but their results strongly depend on the initial model and may converge to local minima. Mo...
