텐서플로우:: 작전:: SparseFillEmptyRowsGrad
#include <sparse_ops.h> SparseFillEmptyRows 의 기울기입니다.
요약
[N] 모양의 reverse_index_map 및 [N_full] 모양의 grad_values(여기서 N_full >= N 벡터를 가져와 데이터를 d_values 또는 d_default_value 에 복사합니다. 여기서 d_values 는 [N] 모양이고 d_default_value 는 스칼라입니다.
d_values[j] = grad_values[reverse_index_map[j]] d_default_value = sum_{k : 0 .. N_full - 1} ( grad_values[k] * 1{k는 reverse_index_map에 없음})
인수:
보고:
-
Output d_값: 1-D. 값으로의 역전파. -
Output d_default_value: 0-D. default_value로의 역전파.
