(out_channels=64, num_edge_type=4, ch_list=None, n_atom_types=117, input_type='int', scale_adj=False)[source]¶ 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.
Methods
__init__
([out_channels, num_edge_type, …])Initialize self. add_hook
(hook[, name])Registers a link hook. add_link
(name, link)Registers a child link to this chain. add_param
(name[, shape, dtype, initializer])Registers a parameter to the link. add_persistent
(name, value)Registers a persistent value to the link. 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. disable_update
()Disables update rules of all parameters under the link hierarchy. enable_update
()Enables update rules of all parameters under the link hierarchy. init_scope
()Creates an initialization scope. links
([skipself])Returns a generator of all links under the hierarchy. namedlinks
([skipself])Returns a generator of all (path, link) pairs under the hierarchy. namedparams
([include_uninit])Returns a generator of all (path, param) pairs under the hierarchy. params
([include_uninit])Returns a generator of all parameters under the link hierarchy. register_persistent
(name)Registers an attribute of a given name as a persistent value. repeat
(n_repeat[, mode])Repeats this link multiple times to make a Sequential
.serialize
(serializer)Serializes the link object. to_cpu
()Copies parameter variables and persistent values to CPU. to_gpu
([device])Copies parameter variables and persistent values to GPU. to_intel64
()Copies parameter variables and persistent values to CPU. zerograds
()Initializes all gradient arrays by zero. Attributes
local_link_hooks
Ordered dictionary of registered link hooks. update_enabled
True
if at least one parameter has an update rule enabled.within_init_scope
True if the current code is inside of an initialization scope. xp
Array module for this link.
