Interactive visualization supplemental to "Bayesian elastic Full-Waveform Inversion using Hamiltonian Monte Carlo".
Visualization of sampling results of probabilistic full-waveform inversion using Hamiltonian Monte Carlo. This program will visualize the correlation structure of the chequerboard models interactively within the acquistition geometry.
This program takes the raw / thinned samples of the Markov chain and computes the correlation matrix. Subsequently, it extracts one row of this matrix and maps it back into the model. In this way, it visualizes the correlation to one specific parameter throughout the medium.
In the correlation visualization, one is able to click on any parameter. The program then recomputes the correlation to that specific parameter, and plots it in the current view.
If all steps below are followed (i.e. all requirements are installed), the program can be started from the program root directory (the folder where you find this file) by running:
python3 gui.py
Or, if you directly want to run the correlation visualization of a specific Markov chain:
python3 correlation_chain_[insert appropriate name].py
This program requires Python 3, and has only been tested with Python 3.7. For the GUI, TKinter is required. This package is typically installed with every Python distribution. On Ubuntu-like systems, it is manually available as:
sudo apt-get install python3-tk
Additionally, it relies on the following packages available through pip:
- numpy
- matplotlib
- pytz
- pillow
To install all:
pip3 install numpy matplotlib pytz pillow
If you have a Conda distribution, you might find installing a separate environment more practical. For this, minimal and exact Anaconda environment specifications are provided in this folder.
Recommended To install with minimal dependencies run:
conda env create -f environment.minimal.yaml
And activation is done by:
conda activate hmcfwi-min
Alternatively For the complete environment (as is used in the development):
conda env create -f environment.exact.yaml
And activation is done by:
conda activate hmcfwi-ex
