SparseApplyAdagradV2

public final class SparseApplyAdagradV2

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:

a c c u m + = g r a d * g r a d

$accum += grad * grad$

v a r - = l r * g r a d * (1 / s q r t (a c c u m))

$var -= lr * grad * (1 / sqrt(accum))$

asOutput()

Returns the symbolic handle of a tensor.

Public Methods

public Output<T> asOutput ()

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static SparseApplyAdagradV2<T> create (Scope scope, Operand<T> var, Operand<T> accum, Operand<T> lr, Operand<T> epsilon, Operand<T> grad, Operand<U> indices, Options... options)

Factory method to create a class wrapping a new SparseApplyAdagradV2 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 SparseApplyAdagradV2

public Output<T> out ()

Same as "var".

public static SparseApplyAdagradV2.Options updateSlots (Boolean updateSlots)

public static SparseApplyAdagradV2.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.
