aliran tensor:: operasi:: Akumulator JarangTerapkanGradien
#include <data_flow_ops.h> Menerapkan gradien renggang ke akumulator tertentu.
Ringkasan
Tidak ditambahkan jika local_step lebih kecil dari global_step akumulator.
Argumen:
- ruang lingkup: Objek Lingkup
- pegangan: Pegangan ke akumulator.
- local_step: Nilai local_step yang digunakan untuk menghitung gradien renggang.
- gradien_indices: Indeks gradien renggang yang akan diakumulasikan. Harus berupa vektor.
- gradien_nilai: Nilai adalah potongan gradien yang bukan nol, dan harus memiliki dimensi pertama yang sama dengan indeks, yaitu nnz yang diwakili oleh indeks dan nilai harus konsisten.
- gradien_bentuk: Bentuk gradien renggang yang akan diakumulasikan.
- has_known_shape: Boolean yang menunjukkan apakah gradien_shape tidak diketahui, dalam hal ini input diabaikan selama validasi.
