Submanifold Convolution
Introduced by Benjamin Graham et al. in 3D Semantic Segmentation with Submanifold Sparse Convolutional Networks
archive 2025-07-28 Description, source and code snippet are the archive's method entry.
Submanifold Convolution (SC) is a spatially sparse convolution operation used for tasks with sparse data like semantic segmentation of 3D point clouds. An SC convolution computes the set of active sites in the same way as a regular convolution: it looks for the presence of any active sites in its receptive field of size fᵈ. If the input has size l then the output will have size (l − f + s)/s. Unlike a regular convolution, an SC convolution discards the ground state for non-active sites by assuming that the input from those sites is zero. For more details see the paper, or the official code here.

Usage over time archive 2025-07-28
Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
