tensorflow::ops::ApplyProximalGradientDescent
#include <training_ops.h>
Update '*var' as FOBOS algorithm with fixed learning rate.
Summary
prox_v = var - alpha * delta var = sign(prox_v)/(1+alpha*l2) * max{|prox_v|-alpha*l1,0}
Args:
- scope: A Scope object
- 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.
- delta: The change.
Optional attributes (see Attrs):
- use_locking: If True, the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
