TensorIndexedSlices

Sparse representation of a set of tensor slices at given indices.

This class if a simple wrapper for a pair (or a set of three) of Tensor objects:

indices: A one-dimensional integer Tensor with shape [D0].
values: An Tensor of any data type, with shape [D0, D1, ..., Dn].
denseShape: Optionally, an integer Tensor with shape [LARGE0, D1, ..., Dn].

An TensorIndexedSlices is typically used to represent a subset of a larger Output, dense, of shape [LARGE0, D1, ..., Dn], where LARGE0 >> D0. The values in indices are the indices in the first dimension of the slices that have been extracted from the larger tensor.

The dense Tensor, dense, represented by TensorIndexedSlices, slices, has:

dense(slices.indices(i), ::, ::, ...) = slices.values(i, ::, ::, ...)

The TensorIndexedSlices class is used primarily in the definition of gradients for operations that have sparse gradients, such as gather.

Note that this is different than SparseTensor which uses multi-dimensional indices and scalar values.
