Аннотация:Neural networks (NN) are widely used for solving various problems of geophysical datainterpretation and processing. The application of the neural network approximation (NNA) methodfor solving inverse problems, including inverse multicriteria problems of geophysics that are reducedto a nonlinear operator equation of first kind (respectively, to a system of operator equations) is considered. The NNA method assumes the construction of an approximate inverse operator of the problem using neural network approximation designs (MLP networks) on the basis of a preliminary constructed set of reference solutions to direct and inverse problems. A review of the application of theNNA method for solving nonlinear inverse problems of geophysics is given. Techniques for estimatingthe practical ambiguity (error) of approximate solutions to inverse multicriteria problems are considered. Results of solving the inverse two-criteria 2D gravimetry problem in combination with magnetometry are presented.
