텐서플로우:: 작전:: FakeQuantWithMinMaxVarsPerChannel
#include <array_ops.h>
float 유형의 '입력' 텐서와 다음 모양 중 하나를 가짜 양자화합니다: [d]
,.
요약
[b, d]
[b, h, w, d]
채널별 min
및 max
모양 [d]
통해 inputs
과 동일한 모양의 텐서를 '출력'합니다.
[min; max]
inputs
데이터의 클램핑 범위를 정의합니다. inputs
값은 양자화 범위( narrow_range
false인 경우 [0; 2^num_bits - 1]
, true인 경우 [1; 2^num_bits - 1]
)로 양자화된 다음 역양자화되어 [min; max]
간격. num_bits
양자화의 비트폭입니다. 2부터 16까지.
양자화하기 전에 min
과 max
값은 다음 논리로 조정됩니다. min <= 0 <= max
갖는 것이 좋습니다. 0
값 범위에 없으면 동작이 예상하지 못할 수 있습니다. 0 < min < max
: min_adj = 0
및 max_adj = max - min
인 경우. min < max < 0
인 경우: min_adj = min - max
및 max_adj = 0
. min <= 0 <= max
: scale = (max - min) / (2^num_bits - 1)
, min_adj = scale * round(min / scale)
및 max_adj = max + min_adj - min
.
이 작업에는 기울기가 있으므로 min
과 max
값을 훈련할 수 있습니다.

It is suggested to have `min \u003c= 0 \u003c= max`. If `0` is not in the range of values, the behavior can be unexpected: If `0 \u003c min \u003c max`: `min_adj = 0` and `max_adj = max - min`. If `min \u003c max \u003c 0`: `min_adj = min - max` and `max_adj = 0`. If `min \u003c= 0 \u003c= max`: `scale = (max - min) / (2^num_bits - 1)`, `min_adj = scale * round(min / scale)` and `max_adj = max + min_adj - min`.\n\nThis operation has a gradient and thus allows for training `min` and `max` values.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n\n\u003cbr /\u003e\n\nReturns:\n\n-
