Nevertheless, two issues impede the usage of GNNs in real scenarios: (1)insufficient labeled molecules forsupervised training; (2)poorgeneralization capability to new-synthesized molecules.

Many PPS, such as Stan [1] or PyMC3 [2], limit the expressiveness of their language to ensure that the programs in their language always correspond tomodels with static support--i.e.

Akeyrequirement forthe success ofsupervised deep learning isalargelabeled dataset - a condition that is difficult to meet in medical image analysis.

Frobenius norm of M λ ( M) Spectrum of M σ ( M) Singular values of M E ( x) Dirichlet energy computed on x H ( G) Homophily coefficient of the graph G A B Kronecker product between A and B vec( M) V ector obtained stacking columns of M . In this section, we give the details on the numerical results in Section 6 . On the contrary, the graph layers do not use any dropout nor non-linearity. A sketch of the algorithm is reported in fLode . Cora, Citeseer, and Pubmed are already undirected graphs: to these, we added self-loops.

In linear regression, interpolating the square loss is equivalent to interpolating many other losses (such as the absolute loss) on the training set. Similarly, in the context of linear classification, many works (Soudry et al. 2018; Ji and Telgarsky 2019; Muthukumar et al. 2021) have shown that optimizing
