MaxPoolingΒΆ

class dgl.nn.mxnet.glob.MaxPooling[source]ΒΆ

Bases: mxnet.gluon.block.Block

Apply max pooling over the nodes in the graph.

\[r^{(i)} = \max_{k=1}^{N_i} \left( x^{(i)}_k \right)\]
forward(graph, feat)[source]ΒΆ

Compute max pooling.

Parameters

  • graph (DGLGraph) – The graph.

  • feat (mxnet.NDArray) – The input feature with shape \((N, *)\) where \(N\) is the number of nodes in the graph.

Returns

The output feature with shape \((B, *)\), where \(B\) refers to the batch size.

Return type

mxnet.NDArray
