ApplyAdam

tensorflow C++ API

tensorflow::ops::ApplyAdam

Update ‘*var’ according to the Adam algorithm.

Summary

lr_t <- learning_rate * sqrt(1 - beta2^t) / (1 - beta1^t) m_t <- beta1 * m_{t-1} + (1 - beta1) * g_t v_t <- beta2 * v_{t-1} + (1 - beta2) * g_t * g_t variable <- variable - lr_t * m_t / (sqrt(v_t) + epsilon)

Arguments:

  • scope: A Scope object
  • var: Should be from a Variable().
  • m: Should be from a Variable().
  • v: Should be from a Variable().
  • beta1_power: Must be a scalar.
  • beta2_power: Must be a scalar.
  • lr: Scaling factor. Must be a scalar.
  • beta1: Momentum factor. Must be a scalar.
  • beta2: Momentum factor. Must be a scalar.
  • epsilon: Ridge term. Must be a scalar.
  • grad: The gradient.

Optional attributes (seeAttrs):

  • use_locking: If True, updating of the var, m, and v tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
  • use_nesterov: If True, uses the nesterov update.

Returns:

ApplyAdam block
