EM-ML algorithm for track initialization using possibly noninformative data
收藏 引用
IEEE TRANSACTIONS ON AEROSPACE AND ELECTRONIC SYSTEMS 2005年 第3期41卷 1030-1048页
作者: Cai, J Sinha, A Kirubarajan, T McMaster Univ Dept Elect & Comp Engn Hamilton ON L8S 4K1 Canada
Initializing and maintaining a track for a low observable (LO) (low SNR, low target detection probability and high false alarm rate) target can be very challenging because of the low information content of measurement... 详细信息

Convergence and Stability of Iteratively Re-weighted Least Squares algorithms
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2014年 第1期62卷 183-195页
作者: Ba, Demba Babadi, Behtash Purdon, Patrick L. Brown, Emery N. MIT Dept Brain & Cognit Sci Cambridge MA 02139 USA Massachusetts Gen Hosp Dept Anesthesia Crit Care & Pain Med Boston MA 02114 USA MIT Harvard MIT Div Hlth Sci & Technol Cambridge MA 02139 USA
In this paper, we study the theoretical properties of iteratively re-weighted least squares (IRLS) algorithms and their utility in sparse signal recovery in the presence of noise. We demonstrate a one-to-one correspon... 详细信息

Relevance feedback based on non-negative matrix factorisation for image retrieval
收藏 引用
IEE PROCEEDINGS-VISION IMAGE AND SIGNAL PROCESSING 2006年 第4期153卷 436-444页
作者: Liang, D. Yang, J. Chang, Y. Shanghai Jiao Tong Univ Inst Image Proc & Pattern Recognit Shanghai 200030 Peoples R China
As a powerful tool for content-based image retrieval, many techniques have been proposed for relevance feedback. A non-negative matrix factorisation (NMF)-based relevance feedback approach is introduced. This approach... 详细信息

Adults Use Cross-Situational Statistics for Word Learning in a Conservative Way
收藏 引用
IEEE TRANSACTIONS ON COGNITIVE AND DEVELOPMENTAL SYSTEMS 2020年 第2期12卷 232-242页
作者: Aussems, Suzanne Vogt, Paul Univ Warwick Dept Psychol Coventry CV4 7AL W Midlands England Tilburg Univ Dept Cognit Sci & Artificial Intelligence NL-5000 Tilburg Netherlands
This paper examined how much adults rely on cross-situational information in word learning by comparing their gaze behavior in a word learning task with models of four learning strategies. We manipulated the input typ... 详细信息

Stochastic degradation process modeling and remaining useful life estimation with flexible random-effects
收藏 引用
JOURNAL OF THE FRANKLIN INSTITUTE-ENGINEERING AND APPLIED MATHEMATICS 2017年 第6期354卷 2477-2499页
作者: Zhang, Zhengxin Hu, Changhua Si, Xiaosheng Zhang, Jianxun Zheng, Jianfei Xian Inst High Tech Xian 710025 Shaanxi Provinc Peoples R China Tsinghua Univ Dept Automat Beijing 100084 Peoples R China
Models with random-effects are generally used in the field of degradation modeling and remaining useful life (RUL) estimation for describing unit-to-unit variability. The wide employment of parameters, which is assume... 详细信息

Multiple model approach to linear parameter varying time-delay system identification with EM algorithm
收藏 引用
JOURNAL OF THE FRANKLIN INSTITUTE-ENGINEERING AND APPLIED MATHEMATICS 2014年 第12期351卷 5565-5581页
作者: Yang, Xianqiang Gao, Huijun Harbin Inst Technol Res Inst Intelligent Control & Syst Harbin 150080 Heilongjiang Peoples R China
This paper is concerned with the identification problem of linear parameter varying (LPV) time-delay systems. Due to inherent nonlinearity, the industrial processes are often approximately described by an LPV model co... 详细信息
