摘要:

气候变化给人类带来的挑战刺激了一个快速发展的人工智能研究领域,该领域专注于气候变化应用。气候变化AI(CCAI)社区致力于解决一系列具有挑战性的问题,这些问题通常涉及物理约束的ML或异构时空数据。期望使用自动化机器学习(AutoML)技术来自动找到给定数据集的高性能架构和超参数。在这项工作中,我们对三个高杠杆CCAI应用程序的流行AutoML库进行了基准测试:气候建模,风力发电预测和催化剂发现。我们发现,开箱即用的AutoML库目前未能有意义地超越人类设计的CCAI模型的性能。然而,我们也发现了一些关键的弱点,这是因为大多数AutoML技术都是为计算机视觉和NLP应用定制的。例如,虽然为图像和语言数据设计了几十个搜索空间,但没有一个是为时空数据设计的。解决这些关键弱点可以导致发现新的架构,在众多的CCAI应用程序中产生实质性的性能增益。因此,我们呼吁AutoML社区采取行动,因为在CCAI的AutoML空间中,未来的工作有许多具体的,有前途的方向。我们在https://github.com/climate-change-automl/climate-change-automl上发布了我们的代码和资源列表。

英文摘要:

The challenge that climate change poses to humanity has spurred a rapidly developing field of artificial intelligence research focused on climate change applications. The climate change AI (CCAI) community works on a diverse, challenging set of problems which often involve physics-constrained ML or heterogeneous spatiotemporal data. It would be desirable to use automated machine learning (AutoML) techniques to automatically find high-performing architectures and hyperparameters for a given dataset. In this work, we benchmark popular AutoML libraries on three high-leverage CCAI applications: climate modeling, wind power forecasting, and catalyst discovery. We find that out-of-the-box AutoML libraries currently fail to meaningfully surpass the performance of human-designed CCAI models. However, we also identify a few key weaknesses, which stem from the fact that most AutoML techniques are tailored to computer vision and NLP applications. For example, while dozens of search spaces have been designed for image and language data, none have been designed for spatiotemporal data. Addressing these key weaknesses can lead to the discovery of novel architectures that yield substantial performance gains across numerous CCAI applications. Therefore, we present a call to action to the AutoML community, since there are a number of concrete, promising directions for future work in the space of AutoML for CCAI. We release our code and a list of resources at https://github.com/climate-change-automl/climate-change-automl.
