英文摘要:
In this work, we discuss the Automatic Adjoint Differentiation (AAD) for functions of the form $G=\\frac{1}{2}\\sum_1^m (Ey_i-C_i)^2$, which often appear in the calibration of stochastic models. { We demonstrate that it allows a perfect SIMD\\footnote{Single Input Multiple Data} parallelization and provide its relative computational cost. In addition we demonstrate that this theoretical result is in concordance with numeric experiments.}

中文摘要:
在这项工作中,我们讨论了形式为$G=\\ frac{1}{2}\\ sum\\u 1 ^ m(Ey\\u i-C\\u i)^ 2$的函数的自动伴随微分(AAD),这通常出现在随机模型的校准中。{我们证明它允许完美的SIMD脚注{单输入多数据}并行化,并提供其相对计算成本。此外,我们还证明了这个理论结果与数值实验是一致的
