Unsupervised Variable Selection for Ultrahigh-Dimensional Clustering Analysis
Tonglin Zhang, Huyunting Huang
Compared to supervised variable selection, the research on unsupervised variable selection is far behind. A forward partial-variable clustering full-variable loss (FPCFL) method is…
Unsupervised Machine Learning for Detecting and Locating Human-Made Objects in 3D Point Cloud
Hong Zhao, Huyunting Huang, Tonglin Zhang +3
A 3D point cloud is an unstructured, sparse, and irregular dataset, typically collected by airborne LiDAR systems over a geological region. Laser pulses emitted from these systems…
Managing Controlled Unclassified Information in Research Institutions
Baijian Yang, Carolyn Ellis, Preston Smith +1
In order to operate in a regulated world, researchers need to ensure compliance with ever-evolving landscape of information security regulations and best practices. This work expla…
Multiple Learning for Regression in big data
Xiang Liu, Ziyang Tang, Huyunting Huang +2
Regression problems that have closed-form solutions are well understood and can be easily implemented when the dataset is small enough to be all loaded into the RAM. Challenges ari…
