Numerics and Experiments

Two algorithms for solving the histogram task

  • The experiments for this section from the paper are can be run using run_histogram.py, and plotted using 01-histogram.ipynb

A model of positional and semantic embeddings

  • The results are visualized in 02-toy_model_plots.ipynb using the raw csv's available in the repo. The raw data is created in separated files for theory and empirics.

  • Theory:

    • The numerical solution of equations (7-8) of Result 4.2 is implemented in theory/theory.ipynb. The notebooks uses the quadpy package for 2d numerical integration. Note that this method is not adaptative, and depending on the accuracy of the selected scheme, the iterative resolution of (7-8) may present instabilities or inaccuracies, notably if too low of an order is selected.

  • Empirics:

    • The module src.empirics_mixed_teacher_softmax is used for the student with rank 1, for the experiments presented in the main and the appendix
    • The module src.empirics_mixed_teacher_softmax_r2 is used for the student with rank 2, for the experiments presented in the appendix
    • The experiments frequired for all figures can be run using the scripts
      • run_<exp_name>.sh
    • The original data is quite large, so it can be processed to csvs using the convert_data.ipynb
    • The csvs are available in the repository, while the raw data is available upon request to the authors
