Op

@Operator
public final class ResourceApplyFtrlV2
extends PrimitiveOp

Update '*var' according to the Ftrl-proximal scheme.

grad_with_shrinkage = grad + 2 * l2_shrinkage * var accum_new = accum + grad_with_shrinkage * grad_with_shrinkage linear += grad_with_shrinkage + (accum_new^(-lr_power) - accum^(-lr_power)) / lr * var quadratic = 1.0 / (accum_new^(lr_power) * lr) + 2 * l2 var = (sign(linear) * l1 - linear) / quadratic if |linear| > l1 else 0.0 accum = accum_new

Factory method to create a class to wrap a new ResourceApplyFtrlV2 operation to the graph.

Parameters:

scope - current graph scope

var - Should be from a Variable().

accum - Should be from a Variable().

linear - Should be from a Variable().

grad - The gradient.

lr - Scaling factor. Must be a scalar.

l1 - L1 regulariation. Must be a scalar.

l2 - L2 shrinkage regulariation. Must be a scalar.

l2Shrinkage -

lrPower - Scaling factor. Must be a scalar.

options - carries optional attributes values

Returns:

a new instance of ResourceApplyFtrlV2

useLocking

public static ResourceApplyFtrlV2.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.
