Local subspace analysis for astronomical object detection and star/galaxy classification
Zhiyong Liu, Kai Chun Chiu, Lei Xu · 2003
A typical astronomical object detection and star/galaxy classification system is improved via considering a local subspace model which is developed under Bayesian ying-yang (BYY) normalization learning. Experimental result shows the model is beneficial to the tasks of feature extraction and clustering analysis of the original system.
