ResourceApplyProximalAdagrad

public final class ResourceApplyProximalAdagrad

Update '*var' and '*accum' according to FOBOS with Adagrad learning rate.

accum += grad grad prox_v = var - lr grad (1 / sqrt(accum)) var = sign(prox_v)/(1+lr l2) max{|prox_v|-lr l1,0}

Constant Value: "ResourceApplyProximalAdagrad"

Public Methods

public static ResourceApplyProximalAdagrad create ( Scope scope, Operand <?> var, Operand <?> accum, Operand <T> lr, Operand <T> l1, Operand <T> l2, Operand <T> grad, Options... options)

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

Parameters
scope current scope
var Should be from a Variable().
accum Should be from a Variable().
lr Scaling factor. Must be a scalar.
l1 L1 regularization. Must be a scalar.
l2 L2 regularization. Must be a scalar.
grad The gradient.
options carries optional attributes values
Returns
  • a new instance of ResourceApplyProximalAdagrad

public static ResourceApplyProximalAdagrad.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.
