Entity Classification

AIFB: accuracy 92.78% (5 runs, DGL), 95.83% (paper)

python3 entity_classify.py -d aifb --testing --gpu 0

MUTAG: accuracy 71.47% (5 runs, DGL), 73.23% (paper)

python3 entity_classify.py -d mutag --l2norm 5e-4 --n-bases 30 --testing --gpu 0

BGS: accuracy 93.10% (5 runs, DGL n-base=25), 83.10% (paper n-base=40)

python3 entity_classify.py -d bgs --l2norm 5e-4 --n-bases 25 --testing --gpu 0
