Notebooks with examples:

  1. Dataset and explainability readout Open In Colab
  2. Simple training and evaluation Open In Colab
  3. Performance analysis for all models shown in the paper Open In Colab
  4. Focal averaging example Open In Colab


This database contains:

  1. 2-dimensional photoelectron momentum distributions resulting from ionization of Argon target by femtosecond laser pulses:
    1. data_raw/ - results of the simulations and experiments that are in their original format. Details about the data are in the README files.
    2. data_preprocessed/ - data from data_raw that has a uniform numpy format (same momentum grid) with labels and can be used directly for the machine learning part.
  2. models/
    1. models.tar.gz - all 400 pretrained deep convolutional neural network regression models trained in this project (very large)
    2. QProp_Ar_small_sample.npz_SL_0.0__BayesianVGG16__1000.h5 - one example of a model trained on a small dataset, used in the jupyter notebook example 02_training.ipynb
  3. analysis_all_model.pkl - python pickle with benchmarks of all trained models. Used in the 03_evaluation_all_models.ipynb notebook.
  4. explainability.npz - numpy archive with numerical results of the explainability part of the paper. It is used by the 01_dataset_readout.ipynb notebook.
