Table 1. Dataset properties and SDS model parameters. For each dataset, we focus on the properties that our model aims to reproduce. Properties that are irrelevant for our model, or that cannot be measured directly, are omitted. The parameters are tuned independently for each dataset. Note that for NanoBank, we set p_d = 0.001, however in this case the parameter is irrelevant, because we do not use this dataset to validate relationships involving disciplines.
