tensorflow:: אופס:: FakeQuantWithMinMaxVarsPerChannel
#include <array_ops.h> לכמת מזויף את טנסור 'הכניסות' מסוג float ואחת הצורות: [d] ,.
תַקצִיר
[b, d] [b, h, w, d] באמצעות צפים לכל ערוץ min max של צורה [d] ל-'outputs' טנסור בעל צורה זהה inputs .
[min; max] מגדירים את טווח ההידוק עבור נתוני inputs . ערכי inputs מקוונטים לטווח הכימות ( [0; 2^num_bits - 1] כאשר narrow_range הוא false ו- [1; 2^num_bits - 1] כאשר הוא נכון) ולאחר מכן דה-קוונטיזציה ומוצאת כצף ב- [min; max] מרווח. num_bits הוא רוחב הסיביות של הקוונטיזציה; בין 2 ל-16, כולל.
לפני הקוונטיזציה, ערכי min max מותאמים לפי ההיגיון הבא. מומלץ לקבל min <= 0 <= max . אם 0 אינו בטווח הערכים, ההתנהגות יכולה להיות בלתי צפויה: אם 0 < min < max : min_adj = 0 ו max_adj = max - min . אם min < max < 0 : min_adj = min - max ו max_adj = 0 . אם min <= 0 <= max : scale = (max - min) / (2^num_bits - 1) , min_adj = scale * round(min / scale) and max_adj = max + min_adj - min .
לפעולה זו יש שיפוע ובכך מאפשרת אימון ערכי min max .

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-
