Running project

• To run program, use this command: python SMVulDetector.py.
• In addition, you can use specific hyper-parameters to train the model. All the hyper-parameters can be found in parser.py.

Examples:

python SMVulDetector.py --dataset training_data/REENTRANCY_CORENODES_1671
python SMVulDetector.py --dataset training_data/REENTRANCY_CORENODES_1671 --model gcn_modify --n_hidden 192 --lr 0.001 -f 64,64,64 --dropout 0.1 --vector_dim 100 --epochs 50 --lr_decay_steps 10,20 

Using script： Repeating 10 times for different seeds with train.sh.

for i in $(seq 1 10);
do seed=$(( ( RANDOM % 10000 )  + 1 ));
python SMVulDetector.py --model gcn_modify --seed $seed | tee logs/smartcheck_"$i".log;
done

Then, you can find the training results in the logs/.
