J. Cent. South Univ. (2019) 26: 2482-2494 DOI: https://doi.org/10.1007/s11771-019-4188-2 Nonlinear inversion for magnetotelluric sounding based on deep belief network WANG He(王鹤)1, 2, 3, LIU Wei(刘威..., this work introduces the deep belief network (DBN) algorithm. Firstly, a network frame is set up for training in different 2D MT models. The network inputs are the apparent resistivities of known models......
