This approach involves removing a subset of network parameters, such as weights or neurons, that are deemed unnecessary or redundant. But at the time of this writing, I did not see conv on sparse tensors being an implemented feature or on the TODO list. and a hybrid CSC tensor will be created, with dense_dim dense I am expecting an exact code change I need to make in order to fix this issue.

Use the utilities in the tf.sparse package to manipulate sparse tensors. DBSTREAM has the ability to recognize clusters in data streams but cannot capture multi-aspect features in tensor streams. The COO encoding for sparse tensors is comprised of: A nonzero value in the context of a tf.sparse.SparseTensor is a value that's not explicitly encoded. You can also construct sparse tensors from dense tensors by using tf.sparse.from_dense, and convert them back to dense tensors by using tf.sparse.to_dense. 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. plain_indices (array_like) Plain dimension (column or row) In contrast, when you apply tf.math.reduce_max to a dense tensor, the output is 0 as expected. values and indices tensor(s) must match.
