On tuning a mean-field model for semi-supervised classification
收藏 引用
JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2022年 第5期2022卷 053402-053402页
作者: Bergamim, Emilio Breve, Fabricio UNESP Inst Geociencias & Ciencias Exatas Ave 24A 1515 Rio Claro SP Brazil
Semi-supervised learning (SSL) has become an interesting research area due to its capacity for learning in scenarios where both labeled and unlabeled data are available. In this work, we focus on the task of transduct... 详细信息

Long-range frustration in T=0 first-step replica-symmetry-broken solutions of finite-connectivity spin glasses

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2007年 第6期2007卷 L06001-L06001页
作者: Zhou, Jie Ma, Hui Zhou, Haijun Chinese Acad Sci Inst Theoret Phys Beijing 100080 Peoples R China
In a finite-connectivity spin glass at the zero-temperature limit, long-range correlations exist among the unfrozen vertices (whose spin values are non-fixed). Such long-range frustrations are partially removed throug... 详细信息

作者: Bayati, Mohsen Borgs, Christian Chayes, Jennifer Zecchina, Riccardo Microsoft Res Cambridge MA 02142 USA Politecn Torino Dept Phys I-10129 Turin Italy
We consider the general problem of finding the minimum weight b-matching on arbitrary graphs. We prove that, whenever the linear programing relaxation of the problem has no fractional solutions, then the cavity or bel... 详细信息
