Fuzzy clustering algorithm can not obtain good clustering effect when the sample characteristic is not obvious and need to determine the number of clusters firstly. For thi0s reason, this paper proposes an adaptive fuzzy kernel clustering algorithm. The algorithm firstly use the adaptive function of clustering number to calculate the optimal clustering number, then the samples of input space is...

We develop new algorithmic methods with provable guarantees for feature selection in regard to categorical data clustering. While is one of the most common approaches reduce dimensionality practice, known are heuristics. study following mathematical model. assume that there some inadvertent (or undesirable) features input unnecessarily increase cost Consequently, we want select a subset origina...

Text clustering and classification are two main tasks of text mining. Feature selection plays the key role in the quality of the clustering and classification results. Although word-based features such as term frequency-inverse document frequency (TF-IDF) vectors have been widely used in different applications, their shortcoming in capturing semantic concepts of text motivated researches to use...
