干中学:结合因果、控制与强化学习操控动态系统

研究问题
如何利用动态系统的观测与离线干预数据,学习能将系统推向目标状态的控制,并连接因果识别、控制和强化学习的视角?
方法与思路
作者介绍一项竞赛,设置初始单次干预的开环任务和逐期设定控制变量的闭环任务,要求参赛者从数据推断有效控制。
材料陈述的贡献
摘要称竞赛为三类研究视角的结合提供实践平台,并公开获胜方案的复现代码,支持在相同任务上尝试其他方法。
阅读关注点
应核对系统生成机制、可用干预数据与任务限制、控制效果的评价标准,以及获胜方案如何使用因果信息和控制反馈。
阅读边界
这是 arXiv 预印本,同行评审及期刊接收未核验;摘要未给出获胜方法细节或成绩,公开代码与方法有效性也未在此核验。

原文摘要

Questions in causality, control, and reinforcement learning go beyond the classical machine learning task of prediction under i.i.d. observations. Instead, these fields consider the problem of learning how to actively perturb a system to achieve a certain effect on a response variable. Arguably, they have complementary views on the problem: In control, one usually aims to first identify the system by excitation strategies to then apply model-based design techniques to control the system. In (non-model-based) reinforcement learning, one directly optimizes a reward. In causality, one focus is on identifiability of causal structure. We believe that combining the different views might create synergies and this competition is meant as a first step toward such synergies. The participants had access to observational and (offline) interventional data generated by dynamical systems. Track CHEM considers an open-loop problem in which a single impulse at the beginning of the dynamics can be set, while Track ROBO considers a closed-loop problem in which control variables can be set at each time step. The goal in both tracks is to infer controls that drive the system to a desired state. Code is open-sourced ( https://github.com/LearningByDoingCompetition/learningbydoing-comp ) to reproduce the winning solutions of the competition and to facilitate trying out new methods on the competition tasks.
