Sparse Sparse Matrix Multiplication torch_sparse.spspmm(indexA, valueA, indexB, valueB, m, k, n) -> (torch.LongTensor, torch.Tensor) Matrix product of two sparse tensors. Both input sparse matrices need to be coalesced (use the coalesced attribute to force). Parameters indexA (LongTen...
SparseTensor即可以与密集(dense)矩阵做乘法,也可以与稀疏矩阵做乘法,即: # Sparse-Dense Matrix Multiplication x = torch.rand(7, 4) out = adj.matmul(x) print(out.shape) # torch.Size([7, 4]) # Sparse-Sparse Matrix Multiplication adj = adj.matmul(adj) 1. 2. 3. 4. 5. 6. 7. 8. ...

此外,修剪器将尝试使 30%的参数归零,如sparse_ratio键中所示: config_list = [{ 'op_types': ['Linear'], 'exclude_op_names': ['layer4'], 'sparse_ratio': 0.3 }] 注意 您可以在nni.readthedocs.io/en/stable/compression/config_list.html找到配置列表接受的键值对的完整列表。 设置了配置列表后,...
In particular the matrix-matrix (both arguments 2-dimensional) supports sparse arguments with the same restrictions as torch.mm() # vector x vector tensor1 = torch.randn(3) tensor2 = torch.randn(3) torch.matmul(tensor1, tensor2).size() # torch.Size([]) # matrix x vector tensor1 =...

Adjacency matrix in CSR (Compressed Sparse Row): Similar format to COO, but compressed on the row indices. This format allows for more efficient row access and faster sparse matrix-matrix multiplication (SpMM). The performance hotspot is sparse matrix related reduction ops. Scatter-Reduce...
在PyTorch中,密集矩阵(dense matrix)和稀疏矩阵(sparse matrix)是两种不同的数据结构,用于存储和处理不同类型的数据。密集矩阵是一个二维数组,其中大部分元素都是非零的;而...
