一种基于互选模式的师范院校教育实习分配系统

本文是关于师范院校教育实习分配系统的研究,包含教育主管模块、师范院校模块和实习学校模块,上述模块通过互联网连接。本系统使教育实习分配完全脱离了纸上操作的模式,实现了科学化、网络化。本文将互选模式引入教育实习分配工作,从而使有网络的地方,实习生都能找到理想的实习学校,实习学校也能找到需要的实习生。调动了实习生和实习学校对于教育实习的积极性,使教育实习发挥真正的作用,对于提高师范教育质量有很强的理论和实践意义。

A bidirectional feature selection method based on mutual information and redundancy-synergy coefficient

Feature subset selection is a fundamental problem of data mining. The mutual information of feature subset is a measure for feature subset containing class feature information. A hashing mechanism is proposed to calculate the mutual information of feature subset. The feature relevancy is defined by mutual information. Redundancy-synergy coefficient, a novel redundancy and synergy measure for features to describe the class feature, is defined. In terms of information maximization rule, a bidirectional heuristic feature subset selection method based on mutual information and redundancy-synergy coefficient is presented. This study’s experiments show the good performance of the new method.
