Class ResourceSparseApplyProximalGradientDescent

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.train.ResourceSparseApplyProximalGradientDescent

All Implemented Interfaces:

Op

@Operator(group="train")
public final class ResourceSparseApplyProximalGradientDescent
extends PrimitiveOp

Sparse update '*var' as FOBOS algorithm with fixed learning rate.

That is for rows we have grad for, we update var as follows: prox_v = var - alpha grad var = sign(prox_v)/(1+alphal2) max{|prox_v|-alphal1,0}

Factory method to create a class wrapping a new ResourceSparseApplyProximalGradientDescent operation.

Parameters:

scope - current scope

var - Should be from a Variable().

alpha - Scaling factor. Must be a scalar.

l1 - L1 regularization. Must be a scalar.

l2 - L2 regularization. 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 ResourceSparseApplyProximalGradientDescent

useLocking

public static ResourceSparseApplyProximalGradientDescent.Options useLocking(Boolean useLocking)

Parameters:

useLocking - If True, the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
