tensorflow:: אופס:: מצבר תנאי דל
#include <data_flow_ops.h>
מצבר מותנה לצבירה של שיפועים דלילים.
תַקצִיר
המצבר מקבל מעברים המסומנים ב-local_step גדול או שווה ל-global_step העדכני ביותר הידוע לצבר. ניתן לחלץ את הממוצע מהמצבר, בתנאי שנצברו מספיק שיפועים. חילוץ הממוצע מאפס אוטומטית את המצטבר ל-0, ומגדיל את ה-global_step שנרשם על ידי המצבר.
טיעונים:
- scope: אובייקט Scope
- dtype: סוג הערך שנצבר.
- צורה: צורת הערכים.
מאפיינים אופציונליים (ראה Attrs
):
- מיכל: אם אינו ריק, מצבר זה ממוקם במיכל הנתון. אחרת, נעשה שימוש במיכל ברירת מחדל.
- shared_name: אם הוא לא ריק, מצבר זה ישותף תחת השם הנתון על פני מספר הפעלות.

The average can be extracted from the accumulator, provided sufficient gradients have been accumulated. Extracting the average automatically resets the aggregate to 0, and increments the global_step recorded by the accumulator.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- dtype: The type of the value being accumulated.\n- shape: The shape of the values.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/sparse-conditional-accumulator/attrs#structtensorflow_1_1ops_1_1_sparse_conditional_accumulator_1_1_attrs)):\n\n- container: If non-empty, this accumulator is placed in the given container. Otherwise, a default container is used.\n- shared_name: If non-empty, this accumulator will be shared under the given name across multiple sessions.\n\n\u003cbr /\u003e\n\nReturns:\n\n-
