public final class
ResourceScatterAdd
Adds sparse updates to the variable referenced by `resource`.
This operation computes
# Scalar indices ref[indices, ...] += updates[...]
# Vector indices (for each i) ref[indices[i], ...] += updates[i, ...]
# High rank indices (for each i, ..., j) ref[indices[i, ..., j], ...] += updates[i, ..., j, ...]
Duplicate entries are handled correctly: if multiple `indices` reference the same location, their contributions add.
Requires `updates.shape = indices.shape + ref.shape[1:]` or `updates.shape = []`.

Public Methods
public static ResourceScatterAdd create (Scope scope, Operand<?> resource, Operand<T> indices, Operand<U> updates)
Factory method to create a class wrapping a new ResourceScatterAdd operation.
Parameters
| scope | current scope |
|---|---|
| resource | Should be from a `Variable` node. |
| indices | A tensor of indices into the first dimension of `ref`. |
| updates | A tensor of updated values to add to `ref`. |
Returns
- a new instance of ResourceScatterAdd
