Pooling and Reshaping

Downsampling, upsampling, and shape manipulation operations for spatial data. Includes average pooling, max pooling, Lp-norm pooling, unpooling for reconstruction, and adaptive pooling for fixed output sizes. Flatten and Unflatten enable seamless transitions between spatial and flat representations.

Flatten	Flattens a contiguous range of dims into a tensor.
Unflatten	Unflatten a tensor dim expanding it to a desired shape.
AvgPool1d	Applies a 1D average pooling over an input signal composed of several input planes.
AvgPool2d	Applies a 2D average pooling over an input signal composed of several input planes.
AvgPool3d	Applies a 3D average pooling over an input signal composed of several input planes.
MaxPool1d	Applies a 1D max pooling over an input signal composed of several input planes.
MaxPool2d	Applies a 2D max pooling over an input signal composed of several input planes.
MaxPool3d	Applies a 3D max pooling over an input signal composed of several input planes.
MaxUnpool1d	Computes a partial inverse of MaxPool1d.
MaxUnpool2d	Computes a partial inverse of MaxPool2d.
MaxUnpool3d	Computes a partial inverse of MaxPool3d.
LPPool1d	Applies a 1D power-average pooling over an input signal composed of several input planes.
LPPool2d	Applies a 2D power-average pooling over an input signal composed of several input planes.
LPPool3d	Applies a 3D power-average pooling over an input signal composed of several input planes.
AdaptiveAvgPool1d	Applies a 1D adaptive average pooling over an input signal composed of several input planes.
AdaptiveAvgPool2d	Applies a 2D adaptive average pooling over an input signal composed of several input planes.
AdaptiveAvgPool3d	Applies a 3D adaptive average pooling over an input signal composed of several input planes.
AdaptiveMaxPool1d	Applies a 1D adaptive max pooling over an input signal composed of several input planes.
AdaptiveMaxPool2d	Applies a 2D adaptive max pooling over an input signal composed of several input planes.
AdaptiveMaxPool3d	Applies a 3D adaptive max pooling over an input signal composed of several input planes.
