torchadf.nn.modules.flatten.Unflatten

class torchadf.nn.modules.flatten.Unflatten(dim, unflattened_size, mode='diag')

Unflattens a dimension of the input over multiple dimensions.

Assumed Density Filtering (ADF) version of torch.nn.Unflatten. The dimension to be unflattened and target shape refer to the first input (mean) Tensor. Respective dimensions for the second input (covariance) Tensor are inferred according to the covariance propagation mode. (For the full covariance mode this can be ambiguous if the number of leading “batch” dimensions is unknown, hence we assume that any dimensions before the specified unflatten dimension are batch dimensions.)

Parameters:
dimint

Dimension to unflatten.

unflattened_size: tuple of int

Shape into which the selected dimension should be unflattened.

mode{“diag”, “diagonal”, “lowrank”, “half”, “full”}, optional

Covariance propagation mode (Default “diag”).
