aliran tensor:: operasi:: ResourceSparseApplyAdagrad
#include <training_ops.h> Perbarui entri yang relevan di '*var' dan '*accum' sesuai dengan skema adagrad.
Ringkasan
Itu untuk baris yang memiliki grad, kami memperbarui var dan accum sebagai berikut: accum += grad * grad var -= lr * grad * (1 / sqrt(accum))
Argumen:
- ruang lingkup: Objek Lingkup
- var: Harus dari Variabel().
- accum: Harus dari Variabel().
- lr: Kecepatan pembelajaran. Pasti skalar.
- lulusan: Gradien.
- indeks: Vektor indeks ke dalam dimensi pertama var dan accum.
Atribut opsional (lihat Attrs ):
- use_locking: Jika
True , pembaruan tensor var dan accum akan dilindungi oleh kunci; jika tidak, perilaku tersebut tidak terdefinisikan, namun mungkin menunjukkan lebih sedikit pertentangan.
