摘要:

文献中已经提出了大量的时间序列预测模型,包括传统的统计模型、机器学习模型和最近的深度学习。然而,选择正确的模型以及在给定数据上表现良好的良好参数值仍然具有挑战性。自动为给定数据集的用户提供一组良好的模型,可以节省使用具有各种可用模型的试错方法以及参数优化的时间和精力。我们提出了AutoAI for Time Series Forecasting(AutoAI-TS),它为用户提供了一个零配置(zero-conf)系统,以有效地训练,优化和选择最佳预测模型。凭借其灵活的零配置设计,AutoAI-TS自动为用户执行所有的数据准备,模型创建,参数优化,训练和模型选择,并提供可供使用的训练模型。对于给定的数据,AutoAI-TS利用各种模型,包括经典统计模型、机器学习(ML)模型、人工智能-ML混合模型和深度学习模型以及各种转换来创建预测管道。然后,它使用建议的T-Daub机制来评估和排名管道,以选择最佳管道。本文详细描述了AutoAI-TS的所有技术方面,以及针对各种用例的各种真实世界数据集的广泛基准测试。基准测试结果表明,AutoAI-TS无需用户手动配置,即可自动训练和选择平均性能优于现有最先进的时间序列预测工具包的管道。

英文摘要:

A large number of time series forecasting models including traditional statistical models, machine learning models and more recently deep learning have been proposed in the literature. However, choosing the right model along with good parameter values that performs well on a given data is still challenging. Automatically providing a good set of models to users for a given dataset saves both time and effort from using trial-and-error approaches with a wide variety of available models along with parameter optimization. We present AutoAI for Time Series Forecasting (AutoAI-TS) that provides users with a zero configuration (zero-conf ) system to efficiently train, optimize and choose best forecasting model among various classes of models for the given dataset. With its flexible zero-conf design, AutoAI-TS automatically performs all the data preparation, model creation, parameter optimization, training and model selection for users and provides a trained model that is ready to use. For given data, AutoAI-TS utilizes a wide variety of models including classical statistical models, Machine Learning (ML) models, statistical-ML hybrid models and deep learning models along with various transformations to create forecasting pipelines. It then evaluates and ranks pipelines using the proposed T-Daub mechanism to choose the best pipeline. The paper describe in detail all the technical aspects of AutoAI-TS along with extensive benchmarking on a variety of real world data sets for various use-cases. Benchmark results show that AutoAI-TS, with no manual configuration from the user, automatically trains and selects pipelines that on average outperform existing state-of-the-art time series forecasting toolkits.
