Deserialize and concatenate
`
SparseTensors
`
from a serialized minibatch.

## Summary


The input
`
serialized_sparse
`
must be a string matrix of shape
`
[N x 3]
`
where
`
N
`
is the minibatch size and the rows correspond to packed outputs of
`
https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/serialize-sparse#classtensorflow_1_1ops_1_1_serialize_sparse
`
. The ranks of the original
`
SparseTensor
`
objects must all match. When the final
`
SparseTensor
`
is created, it has rank one higher than the ranks of the incoming
`
SparseTensor
`
objects (they have been concatenated along a new row dimension).


The output
`
SparseTensor
`
object's shape values for all dimensions but the first are the max across the input
`
SparseTensor
`
objects' shape values for the corresponding dimensions. Its first shape value is
`
N
`
, the minibatch size.


The input
`
SparseTensor
`
objects' indices are assumed ordered in standard lexicographic order. If this is not the case, after this step run
`
https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/sparse-reorder#classtensorflow_1_1ops_1_1_sparse_reorder
`
to restore index ordering.


For example, if the serialized input is a
`
[2 x 3]
`
matrix representing two original
`
SparseTensor
`
objects:

```
index = [ 0]
        [10]
        [20]
values = [1, 2, 3]
shape = [50]
```

<br />


and

```
index = [ 2]
        [10]
values = [4, 5]
shape = [30]
```

<br />


then the final deserialized
`
SparseTensor
`
will be:

```
index = [0  0]
        [0 10]
        [0 20]
        [1  2]
        [1 10]
values = [1, 2, 3, 4, 5]
shape = [2 50]
```

<br />

  N
  ` serialized `
  SparseTensor
  ` objects. Must have 3 columns.
- dtype: The `
  dtype
  ` of the serialized `
  SparseTensor
  ` objects.
