摘要:

金融业的快速变化是由于数据量的不断增加,这给数据处理和数据分析技术带来了革命性的变化,并带来了新的理论和计算挑战。与经典的随机控制理论和其他分析方法相比,强化学习(RL)的新发展能够充分利用大量的金融数据和更少的模型假设,并在复杂的金融环境中改善决策。本文旨在回顾RL方法在金融领域的最新发展和使用。我们介绍了马尔可夫决策过程,这是许多常用的RL方法的设置。然后介绍了各种算法,重点是基于价值和策略的方法,不需要任何模型假设。与神经网络进行连接,以扩展框架,以包含深度RL算法。我们的调查最后讨论了这些RL算法在各种金融决策问题中的应用,包括最优执行,投资组合优化,期权定价和对冲,做市,智能订单路由和机器人建议。

英文摘要:

The rapid changes in the finance industry due to the increasing amount of data have revolutionized the techniques on data processing and data analysis and brought new theoretical and computational challenges. In contrast to classical stochastic control theory and other analytical approaches for solving financial decision-making problems that heavily reply on model assumptions, new developments from reinforcement learning (RL) are able to make full use of the large amount of financial data with fewer model assumptions and to improve decisions in complex financial environments. This survey paper aims to review the recent developments and use of RL approaches in finance. We give an introduction to Markov decision processes, which is the setting for many of the commonly used RL approaches. Various algorithms are then introduced with a focus on value and policy based methods that do not require any model assumptions. Connections are made with neural networks to extend the framework to encompass deep RL algorithms. Our survey concludes by discussing the application of these RL algorithms in a variety of decision-making problems in finance, including optimal execution, portfolio optimization, option pricing and hedging, market making, smart order routing, and robo-advising.
