International Electrical Engineering Congress (iEECON)
作者: Srikote, Gatesakda Meesomboon, Anupap Khon Kaen Univ Fac Engn Dept Elect Engn Khon Kaen 40002 Thailand
In the paper we propose a face verifying algorithm for face recognition that can identify two face mismatch pairs in cases of incorrect decisions. The computational approach taken in this system is performed by the de... 详细信息

European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML PKDD)
作者: Frenay, Benoit de Lannoy, Gael Verleysen, Michel Catholic Univ Louvain ICTEAM Inst Machine Learning Grp B-1348 Louvain Belgium
The performance of traditional classification models can adversely be impacted by the presence of label noise in training observations. The pioneer work of Lawrence and Scholkopf tackled this issue in datasets with in... 详细信息

40th IEEE Conference on Decision and Control
作者: Elliott, RJ Malcolm, WP Univ Calgary Fac Management Calgary AB T2N 1N4 Canada
In this article we consider HMM parameter estimation in the the context of an EM algorithm. The models we study are discrete time Markov chains observed in Gaussian noise. Now formulae for up-dating smoothed estimates... 详细信息
