tf.sparse_merge(sp_ids, sp_values, vocab_size, name=None, already_sorted=False)
Combines a batch of feature ids and values into a single SparseTensor.
The most common use case for this function occurs when feature ids and their corresponding values are stored in Example protos on disk. parse_example will return a batch of ids and a batch of values, and this function joins them into a single logical SparseTensor for use in functions such as sparse_tensor_dense_matmul, sparse_to_dense, etc.
