Robustness Analysis of USmorph. II. Optimizing Feature Extraction, Dimensionality Reduction, and Clustering for Unsupervised Galaxy Morphology Classification
Guanwen Fang, Xiaolei Yin, Yirui Zheng, Zesen Lin et autres
Abstract We conduct a systematic robustness analysis of the unsupervised machine learning module within the hybrid framework USmorph . This module automatically discovers morphological structures from large-scale galaxy images, forming the foundation of the complete classification workflow. We evaluate five pretrained models …
