tensorflow :: ops :: AccumulatorTakeGradient
#include <data_flow_ops.h> Extrai o gradiente médio no ConditionalAccumulator fornecido.
Resumo
Os blocos de operação até que gradientes suficientes (ou seja, mais de num_required) tenham sido acumulados. Se o acumulador já agregou mais do que num_required gradientes, ele retorna a média dos gradientes acumulados. Também incrementa automaticamente o global_step registrado no acumulador em 1 e redefine o agregado para 0.
Argumentos:
- escopo: um objeto Scope
- identificador: o identificador para um acumulador.
- num_required: número de gradientes necessários antes de retornarmos um agregado.
- dtype: O tipo de dados de gradientes acumulados. Precisa corresponder ao tipo de acumulador.
Retorna:
-
Output : a média dos gradientes acumulados.

If the accumulator has already aggregated more than num_required gradients, it returns the average of the accumulated gradients. Also automatically increments the recorded global_step in the accumulator by 1, and resets the aggregate to 0.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- handle: The handle to an accumulator.\n- num_required: Number of gradients required before we return an aggregate.\n- dtype: The data type of accumulated gradients.
