README.md

The repository is organized as follows:

  • Data: input data used in the practical sessions:

  • Notebooks: Python codes and Jupyter Notebooks used in the practical sessions. More specifically,

    • VisualOptimization: Gradient-based optimization of a 2D cost function with visualization of model trajectories.
    • BasicPytorch: Introduction to PyTorch, Linear and Logistic Regression.
    • LearningFunction: A practical look at the Universal Approximation Theorem and its implications for learning functions with NNs.
    • MixtureDensityNetwork: Mixture Density Networks for multi-modal probabilistic predictions
    • WellLogFaciesPrediction: Well Log facies prediction based on Force2020 Challange
    • EventDetection: Seismic event detection with Recurrent NNs
    • SaltNet: U-Net Salt Segmentation based on TGS Kaggle Challange
    • EikonalPINN: Physics-informed NN solution of Eikonal equation

  • Wandb: Example usage of Wandb with Logistic Regression for efficient ML experimentation

Environment

To ensure reproducibility of the results, we have provided a environment.yml file. Ensure to have installed Anaconda or Miniconda on your computer. If you are not familiar with it, we suggesting using the KAUST Miniconda Install recipe. This has been tested both on macOS and Unix operative systems.

After that simply run:

./install_env.sh

It will take some time, if at the end you see the word Done! on your terminal you are ready to go!

Later in the course, it may be useful to have access to a workstation with GPU capabilities (it will speed up your training time). A modified version of the environment and installation files for GPU-powered environment are also provided here.

Various options exist to access a GPU. If you have a personal machine with a GPU you are lucky, take advantage of it. Alternatively, the KAUST Ibex cluster provides a large pool of nodes with different families of GPUs (RTX 2080, P6000, P100, V100). To install the GPU environment follow the following steps:

ssh ${USER}@glogin.ibex.kaust.edu.sa
salloc --time=01:00:00 --gres=gpu:v100:1 
srun --pty bash
./install_env-gpu.sh

A sample SLURM file is provided that allows setting up a Jupyter notebook with GPU capabilities. More details can be found here.
