JOURNAL OF GLOBAL OPTIMIZATION 2014年 第2期58卷 285-319页
作者: Kim, Jingu He, Yunlong Park, Haesun Nokia Inc Sunnyvale CA USA Georgia Inst Technol Sch Math Atlanta GA 30332 USA Georgia Inst Technol Sch Computat Sci & Engn Atlanta GA 30332 USA
We review algorithms developed for nonnegative matrix factorization (NMF) and nonnegative tensor factorization (NTF) from a unified view based on the block coordinate descent (BCD) framework. NMF and NTF are low-rank ... 详细信息

作者: Coloigner, Julie Karfoul, Ahmad Albera, Laurent Comon, Pierre INSERM UMR 1099 F-85000 Rennes France Univ Rennes 1 LTSI Lab F-35000 Rennes France Inst Natl Rech Informat & Automat Ctr Inria Rennes Bretagne Atlantique F-35042 Rennes France AL Baath Univ Fac Mech & Elect Engn Homs Syria Ecole Natl Super Electrochim & Electrome Grenoble Thermodynam & Physicochim Met Lab CNRS Lab GIPSAUMR 5216 F-38402 St Martin Dheres France
Numerical solutions are proposed to fit the CanDecomp/ParaFac (CP) model of real three-way arrays, when the latter are both nonnegative and symmetric in two modes. In other words, a semi-nonnegative INDSCAL analysis i... 详细信息
