Information gain and divergence-based feature selection for machine learning-based text categorization

Most previous works of feature selection emphasized only the reduction of high dimensionality of the feature space. But in cases where many features are highly redundant with each other, we must utilize other means, for example, more complex dependence models such as Bayesian network classifiers. In this paper, we introduce a new information gain and divergence-based feature selection method for statistical machine learning-based text categorization without relying on more complex dependence models. Our feature selection method strives to reduce redundancy between features while maintaining information gain in selecting appropriate features for text categorization. Empirical results are given on a number of dataset, showing that our feature selection method is more effective than Koller and Sahami’s method [Koller, D., & Sahami, M. (1996). Toward optimal feature selection. In Proceedings of ICML-96, 13th international conference on machine learning], which is one of greedy feature selection methods, and conventional information gain which is commonly used in feature selection for text categorization. Moreover, our feature selection method sometimes produces more improvements of conventional machine learning algorithms over support vector machines which are known to give the best classification accuracy.

基于Gabor小波的人脸识别系统的实现

给出了一种基于Gabor小波的人脸识别系统的实现.该方法先利用模板匹配法定位人脸图像的眼睛,然后经过标准化使图像具有相同的基准,其余特征点的搜索采用弹性图匹配方法;特征点的粗略位置根据训练集的人脸结构知识定位,然后使用弹性图簇的数据结构求得特征点的精确位置,当各特征点的精确位置定位后,人脸的Gabor Jets就可求得;样本图像的相似程度可用与人脸特征点对应的GaborJets作度量函数表达.     

Ensemble learning HMM for motion recognition and retrieval by Isomap dimension reduction

INTRODUCTION Now more and more motion capture systems are used to acquire realistic human motion data. Due to the success of the Mocap systems, realistic and highly detailed motion clips are commercially available and widely used for producing animations of human-like characters in a variety of applications, such as simu- lations, video games and animation files. Therefore an efficient motion data recognition and retrieval technique is needed to support motion data processing, such as mot…     

A comparison of feature selection methods for an evolving RSS feed corpus

Previous researchers have attempted to detect significant topics in news stories and blogs through the use of word frequency-based methods applied to RSS feeds. In this paper, the three statistical feature selection methods: χ², Mutual Information (MI) and Information Gain (I) are proposed as alternative approaches for ranking term significance in an evolving RSS feed corpus. The extent to which the three methods agree with each other on determining the degree of the significance of a term on a certain date is investigated as well as the assumption that larger values tend to indicate more significant terms. An experimental evaluation was carried out with 39 different levels of data reduction to evaluate the three methods for differing degrees of significance. The three methods showed a significant degree of disagreement for a number of terms assigned an extremely large value. Hence, the assumption that the larger a value, the higher the degree of the significance of a term should be treated cautiously. Moreover, MI and I show significant disagreement. This suggests that MI is different in the way it ranks significant terms, as MI does not take the absence of a term into account, although I does. I, however, has a higher degree of term reduction than MI and χ². This can result in loosing some significant terms. In summary, χ² seems to be the best method to determine term significance for RSS feeds, as χ² identifies both types of significant behavior. The χ² method, however, is far from perfect as an extremely high value can be assigned to relatively insignificant terms.     

简析“天津市治安维持会”的基本特征

1937年8月1日成立的天津市治安维持会,是日本侵略军在华北占领区最早扶植建立的傀儡组织之一。该伪组织遵照日军意旨,临时代行天津市府职权,在协助日军维持战争初期社会治安、镇压抗日活动等方面发挥了重要作用。本文分析天津市治安维持会的基本特征,如人员构成上的复杂性,政治上的对日依附性,行政上的准政府性,活动内容的示范性,组织上的过渡性等,以期读者对该伪组织的反动本质有进一步地了解和认识。
