| Summary: | The magnetotelluric method is a geophysical method commonly used to map
subsurface resistivity. The subsurface’s true resistivity is generated by inversion of
the magnetotelluric data. This study tries to invert one-dimensional magnetotelluric
data using one of the machine learning methods, the convolutional neural network,
which is heavily inspired by the human nervous system. This method has been tested
on synthetic data with curves of type A, H, K, and Q contaminated with noise. The
inversion results show that the convolutional neural network model could approach
the actual resistivity values and patterns with a fairly small error and exceptionally
fast computation time without initial model guess and iteration. |
