Table 6.

Time taken for training and generation.

Dataset	Training time per epoch (min)	Generation time/sample/sampling iteration (sec)
QM9	6	0.00542
ChEMBL	280	0.00622

Generation time/sample/sampling iteration is measured as: $\frac{t i m e t a k e n t o c a r r y o u t 100 s a m p l i n g i t e r a t i o n s f o r a b a t c h o f J s a m p l e s}{100 J}$ For QM9, J = 2500 whereas for ChEMBL, J = 1500 due to memory constraints.
