Transmission Line Fault-Cause Identification Based on Hierarchical Multiview Feature Selection [PDF]
Applied Sciences, 2021 Fault-cause identification plays a significant role in transmission line maintenance and fault disposal. With the increasing types of monitoring data, i.e., micrometeorology and geographic information, multiview learning can be used to realize the information fusion for better fault-cause identification. To reduce the redundant information of different
