Relational GCN (RelGCN)

See: Michael Schlichtkrull+, Modeling Relational Data with Graph Convolutional Networks. March 2017. arXiv:1703.06103 <https://arxiv.org/abs/1703.06103>

Parameters:
  • out_channels (int) – dimension of output feature vector
  • num_edge_type (int) – number of types of edge
  • ch_list (list) – channels of each update layer
  • n_atom_types (int) – number of types of atoms
  • input_type (str) – type of input vector
  • scale_adj (bool) – If True, then this network normalizes adjacency matrix
__init__(out_channels=64, num_edge_type=4, ch_list=None, n_atom_types=117, input_type='int', scale_adj=False)[source]

Initialize self. See help(type(self)) for accurate signature.

addgrads(link) Accumulates gradient values from given link.
children() Returns a generator of all child links.
cleargrads() Clears all gradient arrays.
copy([mode]) Copies the link hierarchy to new one.
copyparams(link[, copy_persistent]) Copies all parameters from given link.
count_params() Counts the total number of parameters.
delete_hook(name) Unregisters the link hook.
