A Flexible Spatial Autoregressive Modelling Framework for Mixed Covariates of Multiple Data Types
Huiwen Wang, Tingting Huang, Shanshan Wang
Mixed spatial autoregressive (SAR) models with numerical covariates have been well studied. However, as non-numerical data, such as functional data and compositional data, receive…
Spatial Functional Linear Model and its Estimation Method
Tingting Huang, Gilbert Saporta, Huiwen Wang +1
The classical functional linear regression model (FLM) and its extensions, which are based on the assumption that all individuals are mutually independent, have been well studied a…
Degradation Detection Method for Railway Point Machines
Chong Bian, Shunkun Yang, Tingting Huang +3
Point machines (PMs) are used for switching and locking railway turnouts, and are considered one of the most critical elements of a railway signal system. The failure of the point…
Performance Degradation Assessment for Electrical Machines Based on SOM and Hybrid DHMM
Chong Bian, Shunkun Yang, Tingting Huang +3
Aimed at the timely detection of the degradation of electrical machines and the organization of active maintenance, numerous studies on performance degradation assessment have been…
