Biclustering of ARMA time series     

Jeonghwa LEE  Chi-Hyuck JUN 《浙江大学学报(A卷英文版)》2010,(12):959-965

Biclustering is a method of grouping objects and attributes simultaneously in order to find multiple hidden patterns.When dealing with a long time series,there is a low possibility of finding meaningful clusters of whole time sequence.However,we may find more significant clusters containing partial time sequence by applying a biclustering method.This paper proposed a new biclustering algorithm for time series data following an autoregressive moving average （ARMA） model.We assumed the plaid model but modified the algorithm to incorporate the sequential nature of time series data.The maximum likelihood estimation （MLE） method was used to estimate coefficients of ARMA in each bicluster.We applied the proposed method to several synthetic data which were generated from different ARMA orders.Results from the experiments showed that the proposed method compares favorably with other biclustering methods for time series data.  相似文献

Counselor Personality Needs as a Determinant of Functional Specialty Preference     

DANIEL LEE RANDOLPH 《Counselor Education & Supervision》1973,12(4):300-307

The objective of this study was to determine whether personality needs discriminate between counselor trainees who prefer the administrator specialty and those who prefer the practitioner functional specialty. Doctoral students in counselor education at 20 southern universities were asked to complete a three-item questionnaire designed to determine functional specialty preference. Sixty-two subjects who indicated a preference for the administrator functional specialty and 63 subjects who chose the practitioner functional specialty completed the Personality Research Form (PRF). Stepwise discriminant analysis was used to determine the efficacy of PRF variables in discriminating between the administrator and practitioner groups. The results suggest that the PRF may have value as a tool in the selection of counselors.  相似文献

Rational Autonomy, Morality and Education   总被引：1，自引：0，他引：1  

JEE-HUN LEE  COLIN WRINGE 《Journal of Philosophy of Education》1993,27(1):69-78

Some traditional assumptions regarding rational autonomy are examined and criticised. The exclusion of subjective considerations from autonomous choice is shown to be unjustified, as are attempts to identlfji autonomy with morally desirable conduct. Unexpected implications of these conclusions for education and certain other social institutions are also indicated.  相似文献
