MaxPool1d(kernel_size: Union[T, Tuple[T, ...]], stride: Optional[Union[T, Tuple[T, ...]]] = None, padding: Union[T, Tuple[T, ...]] = 0, dilation: Union[T, Tuple[T, ...]] = 1, return_indices: bool = False, ceil_mode: bool = False)¶
Applies a 1D max pooling over an input signal composed of several input planes.
In the simplest case, the output value of the layer with input size and output can be precisely described as:
paddingis non-zero, then the input is implicitly padded with negative infinity on both sides for
paddingnumber of points.
dilationis the stride between the elements within the sliding window. This link has a nice visualization of the pooling parameters.
kernel_size – The size of the sliding window, must be > 0.
stride – The stride of the sliding window, must be > 0. Default value is
padding – Implicit negative infinity padding to be added on both sides, must be >= 0 and <= kernel_size / 2.
dilation – The stride between elements within a sliding window, must be > 0.
return_indices – If
True, will return the argmax along with the max values. Useful for
ceil_mode – If
True, will use ceil instead of floor to compute the output shape. This ensures that every element in the input tensor is covered by a sliding window.
Output: , where
>>> # pool of size=3, stride=2 >>> m = nn.MaxPool1d(3, stride=2) >>> input = torch.randn(20, 16, 50) >>> output = m(input)
