MT 3D inversion with a deep learning framework

Deep learning (DL) based algorithm to realize magnetotelluric (MT) 3D inversion

• The goal of this study is to realize 3D inversion with deep learning algorithm and its practical application of magnetotelluric data, instead of traditional interative processing.
• Because of some limitation, current uploaded code is for testing the trained CNN model with synthetic models only. We will update code with more details in the future.

Requirements:

• Install python 3.8/newer and anaconda packages: conda install keras, tensorflow, scikit-image, opencv, tqdm, pandas, numpy, seaborn, mtpy, etc. libraries; also need download ModEM package for forward modelling.

Instruction:

1. _1_modelpred.py is for test the model prediction with validation datasets
2. updating...

Hardware tested:

• HP-7920 workstation: 56core CPU; 64G memory; one Nvidia Quadro P5000 GPU.
