A NEW ONE-STEP BAND-LIMITED EXTRAPOLATION PROCEDURE USING EMPIRICAL ORTHOGONAL FUNCTIONS

引用

Journal of Electronics(China) 2006年第5期23卷 777-780页

作者： Weng Jianfeng school of Information and Electronic engineering Zhejiang University of Science and Technology Hangzhou 310023 China

A one-step band-limited extrapolation procedure is systematically developed under an a priori assumption of bandwidth. The rationale of the proposed scheme is to expand the known signal segment based on a band-limited basis function set and then to generate a set of Empirical Orthogonal Functions (EOF’s) adaptively from the sample values of the band-limited function set. Simulation results indicate that, in addi- tion to the attractive adaptive feature, this scheme also appears to guarantee a smooth result for inexact data, thus suggesting the robustness of the proposed procedure.

2010 4th International Conference on Intelligent Information Technology Application (IITA2010)

作者： Qiang Huang school of Computing Sciences University of East Anglia Norwich UK Yong Huang school of Information engineering HeNan Institute of Science and Technology XinXiang China HongYan Yi school of Computing Sciences University of East Anglia Norwich UK

This paper presents a novel method of using mixture models with document segmentation to improve the performance of pseudo relevance feedback for document re- trieval. Pseudo-relevance feedback in information retrieval traditionally selects a number of top-ranked documents, from which terms highly related to the initial query are selected to form a new query model for query expansion. However, the query expansion often causes query shift since not all the contents within the document are coherently relevant. In this paper, we propose to build mixture models by combining the original query information with the expanded query language model using aspect model. The experimental results have shown that our proposed methods significantly outperform a number of strong baselines on several large scale TREC collections.
