aliran tensor:: operasi:: TerapkanAdam

#include <training_ops.h>

Perbarui '*var' sesuai dengan algoritma Adam.

Ringkasan

$$lr_t := {learning_rate} * {1 - beta_2^t} / (1 - beta_1^t)$$
$$m_t := beta_1 * m_{t-1} + (1 - beta_1) * g$$
$$v_t := beta_2 * v_{t-1} + (1 - beta_2) * g * g$$
$$variable := variable - lr_t * m_t / ({v_t} + )$$

Argumen:

  • ruang lingkup: Objek Lingkup
  • var: Harus dari Variabel().
  • m: Harus dari Variabel().
  • v: Harus dari Variabel().
  • beta1_power: Harus berupa skalar.
  • beta2_power: Harus berupa skalar.
  • lr: Faktor penskalaan. Pasti skalar.
  • beta1: Faktor momentum. Pasti skalar.
  • beta2: Faktor momentum. Pasti skalar.
  • epsilon: Istilah punggungan. Pasti skalar.
  • lulusan: Gradien.

Atribut opsional (lihat Attrs ):

  • use_locking: Jika True , pembaruan tensor var, m, dan v akan dilindungi oleh kunci; jika tidak, perilaku tersebut tidak terdefinisikan, namun mungkin menunjukkan lebih sedikit pertentangan.
  • use_nesterov: Jika True , gunakan pembaruan nesterov.

Pengembalian:

  • Output : Sama seperti "var".
