MinkowskiPruning¶

class MinkowskiEngine.MinkowskiPruning¶

Remove specified coordinates from a MinkowskiEngine.SparseTensor.

__init__()¶: Initializes internal Module state, shared by both nn.Module and ScriptModule.

forward(input: MinkowskiSparseTensor.SparseTensor, mask: torch.Tensor)¶

Args:

input (MinkowskiEnigne.SparseTensor): a sparse tensor to remove coordinates from.

mask (torch.BoolTensor): mask vector that specifies which one to keep. Coordinates with False will be removed.

Returns:

A MinkowskiEngine.SparseTensor with C = coordinates corresponding to mask == True F = copy of the features from mask == True.

Example:

>>> # Define inputs
>>> input = SparseTensor(feats, coords=coords)
>>> # Any boolean tensor can be used as the filter
>>> mask = torch.rand(feats.size(0)) < 0.5
>>> pruning = MinkowskiPruning()
>>> output = pruning(input, mask)
