The performance of many content analysis methods heavily dependent on the features they are applied. A fundamental problem that makes the content analysis difficult is the curse of dimensionality. In this study, we propose a novel feature reduction method which adopts ensemble approach to measure the divergence between the training set and test set and use the divergence to supervise the featur...
Approximating a divergence between two probability distributions from their samples is a fundamental challenge in statistics, information theory, and machine learning. A divergence approximator can be used for various purposes such as two-sample homogeneity testing, change-point detection, and class-balance estimation. Furthermore, an approximator of a divergence between the joint distribution ...
The foundations of correspondence analysis rests with Pearson's chi-squared statistic. More recently, it has been shown that the Freeman–Tukey statistic plays an important role in and confirmed advantages Hellinger distance have long advocated literature. statistics are two five commonly used special cases Cressie–Read family divergence statistics. Therefore, this paper explores features where ...
