An efficient unsupervised classification model for galaxy morphology: Voting clustering based on coding from ConvNeXt large model
Guanwen Fang, Yao Dai, Zesen Lin +6
In this work, we update the unsupervised machine learning (UML) step by proposing an algorithm based on ConvNeXt large model coding to improve the efficiency of unlabeled galaxy mo…
Preparation for CSST: Star-galaxy Classification using a Rotationally Invariant Supervised Machine Learning Method
Shiliang Zhang, Guanwen Fang, Jie Song +6
Most existing star-galaxy classifiers depend on the reduced information from catalogs, necessitating careful data processing and feature extraction. In this study, we employ a supe…
Testing cosmic anisotropy with Pade approximation and Pantheon+ sample
Jianping Hu, Jian Hu, Xuandong Jia +2
Cosmography can be used to constrain the kinematics of universe in a model-independent way. In this work, we attempted to combine the Pad approximations with the lat…
Anyonic quantum multipartite maskers in the Kitaev model
Yao Shen, Wei-Min Shang, Chi-Chun Zhou +1
The structure of quantum mechanics forbids a bipartite scenario for masking quantum information, however, it allows multipartite maskers. The Latin squares are found to be closely…
