Proximal Mean Field

This code implments the PMF algorithm described in the following paper:

"Proximal Mean-field for Neural Network Quantization", Thalaiyasingam Ajanthan, Puneet K. Dokania, Richard Hartley, and Philip H. S. Torr, ICCV, 2019.

Extensive hyperparamter tuning improved the classification accuracies compared to the original paper. The results are given below and the final hyperparameters can be found in hyperparams.txt.
