### Variational Graph Autoencoder

```math
X' = \sigma(\hat{D}^{-1/2} \hat{A} \hat{D}^{-1/2} X \Theta)
H = enc(X, A) \\
Z_{\mu}, Z_{logσ} = GCN_{\mu}(H, A), GCN_{\sigma}(H, A) \\
\hat{A} = \sigma (ZZ^T)
```

where ``\hat{A} = A + I``, ``A`` denotes the adjacency matrix, and
``\hat{D} = [\hat{d}_{ij}] = \sum_{j=0} [\hat{a}_{ij}]`` is degree matrix.
where ``A`` denotes the adjacency matrix, ``X`` denotes node features.
