Online Alternating Minimization

Pytorch code for paper

Choromanska et al., "Beyond Backprop: Online Alternating Minimization with Auxiliary Variables", PMLR 97:1193-1202, 2019, http://proceedings.mlr.press/v97/choromanska19a.html

Requirements

  • Python 3.5 or above
  • PyTorch 1.1.0
  • Torchvision 0.4
  • Pandas 0.25 (for Higgs dataset dataloader)

These can be installed using pip by running:

pip install -r requirements.txt

Usage

Run the simulations by executing the script run_experiments.sh:

bash run_experiments.sh

Once all simulations are done, plot the results by running the python script plot_results.py:

python plot_results.py

Note

  • This implementation of the feedforward model includes BatchNorm, which generally slightly improves performance upon what reported in the paper. Hyperparameters were tuned for the models with BatchNorm.
