تدفق التوتر:: العمليات:: المجمع الشرطي المتفرق
#include <data_flow_ops.h>
تراكم مشروط لتجميع التدرجات المتفرقة.
ملخص
يقبل المجمع التدرجات المميزة بـ local_step الأكبر أو المساوية لأحدث خطوة عامة معروفة للمراكم. ويمكن استخراج المتوسط من المجمع، بشرط أن يتم تجميع التدرجات الكافية. يؤدي استخراج المتوسط إلى إعادة تعيين التجميع تلقائيًا إلى 0، وزيادة global_step المسجلة بواسطة المجمع.
الحجج:
- النطاق: كائن النطاق
- dtype: نوع القيمة التي يتم تجميعها.
- الشكل: شكل القيم.
السمات الاختيارية (انظر Attrs
):
- الحاوية: إذا لم تكن فارغة، يتم وضع هذا المركم في الحاوية المحددة. وبخلاف ذلك، يتم استخدام حاوية افتراضية.
- Shared_name: إذا لم يكن فارغًا، فستتم مشاركة هذا المجمع تحت الاسم المحدد عبر جلسات متعددة.

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/r2.1/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/r2.1/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-
