论文摘要

在当今快节奏且超级竞争的市场中,AI驱动的决策是必不可少的,这使对工业机器学习(ML)应用的兴趣大大引起了人们的兴趣。目前对分析专家的需求大大超过了供应。解决此问题的一种解决方案是增加ML框架的用户友好性,以使其对非专家更容易访问。自动化机器学习(AUTOML)是通过提供完全自动化的现成解决方案来选择模型选择和高参数调整来解决专业知识问题。本文分析了Automl在业务分析中应用的潜力,这可能有助于提高所有行业中ML的采用率。 H2O AutoML框架是针对三个现实世界数据集上手动调谐的ML模型进行了基准测试的。在实验中使用的所有三个案例研究中,手动调整的ML模型都可以达到性能优势。然而,H2O Automl软件包被证明是相当有效的。它快速,易于使用,并提供可靠的结果,这些结果接近了经过专业调整的ML模型。 H2O Automl框架的当前能力是支持快速原型制作的宝贵工具,并有可能缩短开发和部署周期。它还可以弥合ML专家的供需之间的现有差距,这是朝着业务分析中自动决策的重要一步。最后,在这个迅速变得更加自动化和数字化的世界中,Automl有可能促进人类的能力。

The realization that AI-driven decision-making is indispensable in today's fast-paced and ultra-competitive marketplace has raised interest in industrial machine learning (ML) applications significantly. The current demand for analytics experts vastly exceeds the supply. One solution to this problem is to increase the user-friendliness of ML frameworks to make them more accessible for the non-expert. Automated machine learning (AutoML) is an attempt to solve the problem of expertise by providing fully automated off-the-shelf solutions for model choice and hyperparameter tuning. This paper analyzed the potential of AutoML for applications within business analytics, which could help to increase the adoption rate of ML across all industries. The H2O AutoML framework was benchmarked against a manually tuned stacked ML model on three real-world datasets. The manually tuned ML model could reach a performance advantage in all three case studies used in the experiment. Nevertheless, the H2O AutoML package proved to be quite potent. It is fast, easy to use, and delivers reliable results, which come close to a professionally tuned ML model. The H2O AutoML framework in its current capacity is a valuable tool to support fast prototyping with the potential to shorten development and deployment cycles. It can also bridge the existing gap between supply and demand for ML experts and is a big step towards automated decisions in business analytics. Finally, AutoML has the potential to foster human empowerment in a world that is rapidly becoming more automated and digital.
