SALA: Soft Assignment Local Aggregation for Parameter Efficient 3D Semantic Segmentation

no code implementations29 Dec 2020 Hani Itani, Silvio Giancola, Ali Thabet, Bernard Ghanem

Since it is learnable, this mapping is allowed to be different per layer instead of being applied uniformly throughout the depth of the network.
