class deephyper.keras.layers.MessagePasserNNM(*args: Any, **kwargs: Any)[source]#

Bases: tensorflow.keras.layers.

Message passing kernel.

Parameters

  • state_dim (int) – number of output channels.

  • attn_heads (int) – number of attention heads.

  • attn_method (str) – type of attention methods.

  • aggr_method (str) – type of aggregation methods.

  • activation (str) – type of activation functions.

Methods

build

call

Apply the layer on input tensors.
__call__(*args: Any, **kwargs: Any) → Any#

Call self as a function.

call(inputs, **kwargs)[source]#

Apply the layer on input tensors.

Parameters

inputs (list) – X (tensor): node feature tensor (batch size * # nodes * state dimension) A (tensor): edge pair tensor (batch size * # edges * 2), one is source ID, one is target ID E (tensor): edge feature tensor (batch size * # edges * # edge features) degree (tensor): node degree tensor for GCN attention (batch size * # edges)

Returns

results after edge network, attention and aggregation (batch size * # nodes * state dimension)

Return type

output (tensor)
