tensorflow::ops::ResourceApplyFtrlV2
#include <training_ops.h>
Update '*var' according to the Ftrl-proximal scheme.
Summary
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
Arguments:
- scope: A Scope object
- 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.
- lr_power: Scaling factor. Must be a scalar.
Optional attributes (see Attrs):
- use_locking: 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.
Returns:
