AdaptiveMaxPool1d

class torch.nn.AdaptiveMaxPool1d(output_size, return_indices=False) [source]

Applies a 1D adaptive max pooling over an input signal composed of several input planes.

The output size is L o u t L_{out} , for any input size. The number of output features is equal to the number of input planes.

Parameters
  • output_size (Union[int, Tuple[int]]) – the target output size L o u t L_{out} .
  • return_indices (bool) – if True, will return the indices along with the outputs. Useful to pass to nn.MaxUnpool1d. Default: False
Shape:
  • Input: ( N , C , L i n ) (N, C, L_{in}) or ( C , L i n ) (C, L_{in}) .
  • Output: ( N , C , L o u t ) (N, C, L_{out}) or ( C , L o u t ) (C, L_{out}) , where L o u t = output_size L_{out}=\text{output\_size} .

Examples

>>> # target output size of 5
>>> m = nn.AdaptiveMaxPool1d(5)
>>> input = torch.randn(1, 64, 8)
>>> output = m(input)
