Batch Sizes

[vthost]

Since the graphs in the two datasets have very similar sizes, I wonder why you use these very different batch sizes for the two tasks?

Although they have similar number of nodes, the graphs in two datasets have different number of node types, different edge density, and even slightly different encoders (DVAE_BN uses gated summed X instead of H as message from predecessors, considering d-separation of Bayesian nets). This makes their training losses very different. Thus, the optimal batch sizes are also different.
