JOURNAL OF GLOBAL OPTIMIZATION 2007年 第4期37卷 513-525页
作者: Jollois, F. -X. Nadif, M. Univ Paris 05 CRIP5 F-75270 Paris 06 France Univ Paul Verlaine Metz LITA UFR MIM F-57045 Metz 1 France
In model-based cluster analysis, the expectation-maximization (EM) algorithm has a number of desirable properties, but in some situations, this algorithm can be slow to converge. Some variants are proposed to speed-up... 详细信息

IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING 2007年 第7期54卷 1191-1198页
作者: Khan, Mohammad Emtiyaz Dutt, Deshpande Narayana Univ British Columbia Dept Comp Sci Vancouver BC V6T 1Z4 Canada Indian Inst Sci Dept Elect Commun Engn Bangalore 560012 Karnataka India
We consider the problem of event-related desynchronization (ERD) estimation. In existing approaches, model parameters are usually found manually through experimentation, a tedious task that often leads to suboptimal e... 详细信息

SIAM JOURNAL ON NUMERICAL ANALYSIS 2011年 第4期49卷 1715-1735页
作者: Walker, Homer F. Ni, Peng Worcester Polytech Inst Dept Math Sci Worcester MA 01609 USA
This paper concerns an acceleration method for fixed-point iterations that originated in work of D. G. Anderson [J. Assoc. Comput. Mach., 12 (1965), pp. 547-560], which we accordingly call Anderson acceleration here. ... 详细信息
