英文摘要:
Automatic differentiation is involved for long in applied mathematics as an alternative to finite difference to improve the accuracy of numerical computation of derivatives. Each time a numerical minimization is involved, automatic differentiation can be used. In between formal derivation and standard numerical schemes, this approach is based on software solutions applying mechanically the chain rule to obtain an exact value for the desired derivative. It has a cost in memory and cpu consumption. For participants of financial markets (banks, insurances, financial intermediaries, etc), computing derivatives is needed to obtain the sensitivity of its exposure to well-defined potential market moves. It is a way to understand variations of their balance sheets in specific cases. Since the 2008 crisis, regulation demand to compute this kind of exposure to many different case, to be sure market participants are aware and ready to face a wide spectrum of configurations. This paper shows how automatic differentiation provides a partial answer to this recent explosion of computation to perform. One part of the answer is a straightforward application of Adjoint Algorithmic Differentiation (AAD), but it is not enough. Since financial sensitivities involves specific functions and mix differentiation with Monte-Carlo simulations, dedicated tools and associated theoretical results are needed. We give here short introductions to typical cases arising when one use AAD on financial markets.

中文摘要:
在应用数学中,自动微分作为有限差分的一种替代方法长期存在,以提高导数数值计算的精度。每次涉及数值最小化时,都可以使用自动微分。在形式推导和标准数值格式之间,这种方法基于软件解决方案,机械地应用链式规则,以获得所需导数的精确值。它在内存和cpu消耗方面有成本。对于金融市场的参与者(银行、保险、金融中介机构等),需要计算衍生品,以获得其对定义明确的潜在市场波动的敏感性。这是一种了解特定情况下资产负债表变化的方法。自2008年危机以来,监管部门要求计算许多不同情况下的此类风险敞口,以确保市场参与者意识到并准备好面对广泛的配置。本文展示了自动微分如何为最近的计算量激增提供部分答案。答案的一部分是伴随算法微分(AAD)的直接应用,但这还不够。由于财务敏感性涉及特定功能和混合微分与蒙特卡罗模拟,因此需要专用工具和相关理论结果。我们在此简要介绍在金融市场上使用AAD时出现的典型案例。
