MultiFun-DAG: Multivariate Functional Directed Acyclic Graph

Directed Acyclic Graphical (DAG) models efficiently formulate causal relationships in complex systems. Traditional DAGs assume nodes to be scalar variables, characterizing complex systems under a facile and oversimplified form. This paper considers …

Profile Decomposition based Hybrid Transfer Learning for Cold-start Data Anomaly Detection

Anomaly detection is an essential task for quality management in smart manufacturing. An accurate data-driven detection method usually needs enough data and labels. However, in practice, there commonly exist newly set-up processes in manufacturing, …

Discussion of 'A novel approach to the analysis of spatial and functional data over complex domains'

The dependency structure of complex data is always a challenge in formulating and yielding accurate estimates. Dr Laura M. Sangalli’s paper offers a well-developed method to formulate the boundary spatial dependency by using the PDE regularization …
