tf.raw_ops.ResourceApplyProximalGradientDescent

Update '*var' as FOBOS algorithm with fixed learning rate.

prox_v = var - alpha * delta var = sign(prox_v)/(1+alpha*l2) * max{|prox_v|-alpha*l1,0}

var A Tensor of type resource. Should be from a Variable().
alpha A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, uint16, complex128, half, uint32, uint64. Scaling factor. Must be a scalar.
l1 A Tensor. Must have the same type as alpha. L1 regularization. Must be a scalar.
l2 A Tensor. Must have the same type as alpha. L2 regularization. Must be a scalar.
delta A Tensor. Must have the same type as alpha. The change.
use_locking An optional bool. Defaults to False. If True, the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
name A name for the operation (optional).

The created Operation.
