About the Event

The Internet of things (IoT) enabled systems have become increasingly available in practice. Examples include GM’s OnStar® tele-service system, the InSite® telemonitoring system from GE, smart home appliances and various personalized remote patient monitoring systems. The unprecedented data availability in such connected systems provides significant opportunities for smart data analytics but, at the same time, it reveals critical challenges. First, the high dimensional stream data with heterogeneity, diverse data types and complex spatiotemporal structure often hinders establishing a unified analytics framework. Second, individual-level data has become available in large scale and consequently, there is a pressing need for individualized modeling and prediction. In this talk we try to address some of these challenges, through data analytics methodologies specifically tailored for IoT enabled smart and connected systems. Specifically, we establish a non-parametric modeling framework based on transfer/multitask learning that can predict the evolution of condition/system monitoring signals through borrowing strength from historical and in-service data. This framework leverages on multivariate gaussian processes and functional graphical models to establish a unified data analytics framework that can incorporate functional heterogeneity and diverse data types both quantitative and qualitative. Further, a generic distributed estimation scheme for functional data that scales efficiently to high dimensions and minimizes the negative transfer of knowledge between uncorrelated functional outputs is proposed. Consistency in estimation and variable selection (oracle property) are then established. The methodologies are validated using numerical studies and a case study with real world data in the application to cloud-based vehicle health monitoring service systems.
