Training Details

We have run all the experiments on a CPU with 2.6GHz 6-core Intel Core i7. We conduct extensive hyperparameter tuning for all the baseline algorithms and report the best results obtained. Detailed hyperparameter set up is given in the appendix of the paper. The presentation of the paper is available in slides and the poster is available here.
