摘要:

IBM Research Castor是一个云原生系统,用于在物联网应用程序中管理和部署大量AI时间序列模型。支持使用Python和R建模代码模板,遵循典型的机器学习工作流。一个基于知识的方法来管理模型和时间序列数据,允许使用一般的语义概念来表达功能工程任务。模型模板可以针对语义概念的特定实例以编程方式部署,从而随着物联网应用程序的增长支持模型重用和自动复制。利用无服务器云计算框架自动并行执行部署的模型。经过训练的模型版本和滚动预测的完整历史被持久化,从而实现完整的模型谱系和可追溯性。结果部署在现实世界中的智能电网现场预测应用的报告。还评估了执行多达数万个AI建模任务的可扩展性。

英文摘要:

IBM Research Castor, a cloud-native system for managing and deploying large numbers of AI time-series models in IoT applications, is described. Modelling code templates, in Python and R, following a typical machine-learning workflow are supported. A knowledge-based approach to managing model and time-series data allows the use of general semantic concepts for expressing feature engineering tasks. Model templates can be programmatically deployed against specific instances of semantic concepts, thus supporting model reuse and automated replication as the IoT application grows. Deployed models are automatically executed in parallel leveraging a serverless cloud computing framework. The complete history of trained model versions and rolling-horizon predictions is persisted, thus enabling full model lineage and traceability. Results from deployments in real-world smart-grid live forecasting applications are reported. Scalability of executing up to tens of thousands of AI modelling tasks is also evaluated.
