Peculiarity-oriented mining (POM) is a new data mining method consisting of peculiar data identification and peculiar data analysis. Peculiarity factor (PF) and local peculiarity factor (LPF) are important concepts employed to describe the peculiarity of points in the identification step. One can study the notions at both attribute and record levels. In this paper, a new record LPF called distance...
Excitation source with multi-frequency sinusoids is of importance for bioimpedance spectroscopy (BIS) measurements. This paper describes a novel and simple method to synthesize multi-frequency sinusoids with 2nth primary harmonics based on Walsh functions. The synthesis mechanism is presented detailedly, and after analyzing the Fourier series expression of the periodic signal, the expression of the...
This paper probes into the technique of phonetic explanation of smart guide in the scenic spots, and discusses the possibilities of accessing to data, data matching and phonetic explanation. In the aspect of accessing data, we provide two methods of ensuring scenic scale. And we solve the repeatedly playing phonetic explanation by software programming.
Attribute reduction of an information system is a key problem in rough set theory and its applications. Using computational intelligence (CI) tools to solve such problems has recently fascinated many researchers. In this paper, we consider a meta-heuristic of scatter search to solve the attribute reduction problem in rough set theory. The proposed method, called scatter search attribute reduction...
