Fuzzy support vector machine analysis in EEG classification
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 5, Issue 2
Abstract
Brain Computer Interface (BCI) technology, provides a direct electronic interface between brain and computer. It enables people with movement disabilities meet their main needs. BCI systems have three parts as input, output, and a processing algorithm that maintains a relation between input and output. The algorithm has three parts of preprocessing, feature extraction and classification. In this article after pre processing the signal we used fractal features like Petrosian and Sevcik’s methods to extract features. In classification we used fuzzy support vector machines and compared it with three other classifiers. In final we resulted that fuzzy support vector machines with Petrosian fractal features has the most classification accuracy (82%) than others but its computation time with two fractal features as Petrosian and Sevcik’s features is not the best but LDA (linear Discriminate Analysis) with Petrosian fractal features has the best computation time (0.14s).

Scrutiny of effect and relationship of increasing the rate of trade on economic development
The main aim of this study is to establish relationship between increasing the rate of trade and economic development. In the fact, it is a priori difficult to establish relationship between increasing the rate of trade...
Anti fuzzy ideals of ordered semigroups
In this paper we introduce the notion of anti ordered fuzzy points of an ordered semigroup S, and give a characterization of anti fuzzy left (resp. right) ideals of orderedsemigroup S. We also introduce the concepts ofan...
The effects of super-absorbent, vermicompost and different levels of irrigation water salinity on soil saturated hydraulic conductivity and Porosity and Bulk density
It can be said arguably that low hydraulic conductivity and rapid effect of salinity on it, is among the biggest problems in heavy-textured soils. With the aim of dispelling this problem, a project was done as factorial...
