If you'd like sparse convolution without the freedom to specify the sparsity pattern yourself, take a look at dilated conv (also called atrous conv). nn.Linear on sparse input, however, is supported. A commonly used technique is pruning, where the weight tensors of a DNN are modified to be sparse . ]], grad_fn=), size=(2, 3), nnz=3, layout=torch.sparse_coo). Sets the seed for generating random numbers.

The example below shows you how to pass a sparse tensor as an input to a Keras model if you use only layers that support sparse inputs. Read arbitrary sparse data into a tf.sparse.SparseTensor using tf.io.SparseFeature, which uses three separate feature keys to store the indices, values, and dense_shape. This talks about the current state of sparse tensors in PyTorch. Note that some ops like tf.sparse.reduce_max do not treat missing values as if they were zero. - sparse x sparse -> sparse initially False. DBSTREAM has the ability to recognize clusters in data streams but cannot capture multi-aspect features in tensor streams. Similar to torch.mm (), if mat1 is a (n \times m) (n m) tensor, mat2 is a (m \times p) (mp) tensor, out will be a (n \times p) (np) tensor.

Right now we only have sparse x dense -> dense and sparse x dense -> sparse, because thats what we needed for sparse Embedding updates. Equivalently, you can follow the design pattern below for earlier versions of TensorFlow: Sparse tensors work transparently with these TensorFlow APIs: Examples are shown below for a few of the above APIs.
