扩展开放式Bandit管道以模拟行业挑战

Extending Open Bandit Pipeline to Simulate Industry Challenges

Bram van den Akker, Niklas Weber, Felipe Moraes, Dmitri Goldenberg

摘要:

Bandit算法通常用于电子商务行业,当预先标记的数据不可用时,用于训练机器学习(ML)系统。然而,行业环境带来了各种挑战,使得在实践中实现强盗算法变得不容易。在本文中,我们详细阐述了政策外优化,延迟奖励,概念漂移,奖励设计和业务规则约束的挑战,从业者在Booking.com应用时遇到的强盗算法。我们的主要贡献是对Open Bandit Pipeline(OBP)框架的扩展。我们为上述一些挑战提供模拟组件,为未来的从业者,研究人员和教育工作者提供解决电子商务行业遇到的挑战的资源。

英文摘要:

Bandit algorithms are often used in the e-commerce industry to train Machine Learning (ML) systems when pre-labeled data is unavailable. However, the industry setting poses various challenges that make implementing bandit algorithms in practice non-trivial. In this paper, we elaborate on the challenges of off-policy optimisation, delayed reward, concept drift, reward design, and business rules constraints that practitioners at Booking.com encounter when applying bandit algorithms. Our main contributions is an extension to the Open Bandit Pipeline (OBP) framework. We provide simulation components for some of the above-mentioned challenges to provide future practitioners, researchers, and educators with a resource to address challenges encountered in the e-commerce industry.
