Running a model

To run the model, execute the following command:

 CUDA_VISIBLE_DEVICES=0 python main.py --dataset FB15k-237 --num_iterations 500 --batch_size 128
                                       --lr 0.0005 --dr 1.0 --edim 200 --rdim 200 --input_dropout 0.3 
                                       --hidden_dropout1 0.4 --hidden_dropout2 0.5 --label_smoothing 0.1

Available datasets are:

FB15k-237
WN18RR
FB15k
WN18

To reproduce the results from the paper, use the following combinations of hyperparameters with batch_size=128:
