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".
