public final class
ResourceSparseApplyAdagradV2
Update relevant entries in '*var' and '*accum' according to the adagrad scheme.
That is for rows we have grad for, we update var and accum as follows: accum += grad * grad var -= lr * grad * (1 / sqrt(accum))

Public Methods
public static ResourceSparseApplyAdagradV2 create ( Scope scope, Operand <?> var, Operand <?> accum, Operand <T> lr, Operand <T> epsilon, Operand <T> grad, Operand <U> indices, Options... options)
Factory method to create a class wrapping a new ResourceSparseApplyAdagradV2 operation.
Parameters
scope | current scope |
---|---|
var | Should be from a Variable(). |
accum | Should be from a Variable(). |
lr | Learning rate. Must be a scalar. |
epsilon | Constant factor. Must be a scalar. |
grad | The gradient. |
indices | A vector of indices into the first dimension of var and accum. |
options | carries optional attributes values |
Returns
- a new instance of ResourceSparseApplyAdagradV2
public static ResourceSparseApplyAdagradV2.Options useLocking (Boolean useLocking)
Parameters
useLocking | If `True`, updating of the var and accum tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention. |
