テンソルフロー::作戦:: SparseConditionalAccumulator
#include <data_flow_ops.h>
疎な勾配を集約するための条件付きアキュムレータ。
まとめ
アキュムレータは、アキュムレータが認識している最新の global_step 以上の local_step でマークされた勾配を受け入れます。十分な勾配が蓄積されていれば、平均はアキュムレータから抽出できます。平均を抽出すると、集計は自動的に 0 にリセットされ、アキュムレータによって記録される global_step が増加します。
引数:
- スコープ:スコープオブジェクト
- dtype: 蓄積される値のタイプ。
- 形状: 値の形状。
オプションの属性 ( Attrs
を参照):
- コンテナ: 空でない場合、このアキュムレータは指定されたコンテナに配置されます。それ以外の場合は、デフォルトのコンテナが使用されます。
- shared_name: 空でない場合、このアキュムレータは指定された名前で複数のセッション間で共有されます。

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- [Output](/versions/r2.1/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): The handle to the accumulator.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n|
