tensorflow::ops::SparseToDense
#include <sparse_ops.h>
Converts a sparse representation into a dense tensor.
Summary
Builds an array dense
with shape output_shape
such that
```prettyprint If sparse_indices is scalar
dense[i] = (i == sparse_indices ? sparse_values : default_value)
If sparse_indices is a vector, then for each i
dense[sparse_indices[i]] = sparse_values[i]
If sparse_indices is an n by d matrix, then for each i in [0, n)
dense[sparse_indices[i][0], ..., sparse_indices[i][d-1]] = sparse_values[i] ```
All other values in dense
are set to default_value
. If sparse_values
is a scalar, all sparse indices are set to this single value.
Indices should be sorted in lexicographic order, and indices must not contain any repeats. If validate_indices
is true, these properties are checked during execution.
Arguments:
- scope: A Scope object
- sparse_indices: 0-D, 1-D, or 2-D.
sparse_indices[i]
contains the complete index wheresparse_values[i]
will be placed. - output_shape: 1-D. Shape of the dense output tensor.
- sparse_values: 1-D. Values corresponding to each row of
sparse_indices
, or a scalar value to be used for all sparse indices. - default_value: Scalar value to set for indices not specified in
sparse_indices
.
Optional attributes (see Attrs
):
- validate_indices: If true, indices are checked to make sure they are sorted in lexicographic order and that there are no repeats.
Returns:
-
Output
: Dense output tensor of shapeoutput_shape
.
