Java is Object-Oriented Programming Languages (OOPL) that widely used for software development. But Java has a limitation for working with Domain-Specific Languages (DSLs). Java language structure and syntax has not more support for working with DSLs and including type of Java language. Static language likes Java does not flexible more for DSLs handle. This limitation has to solve by adding new language...
Search engines have been one of the most popular ways for people to find web pages of interest. Presently, when a user enters a keyword in a search engine, the search results are usually presented the same result to other users who search the same keyword, which might not be related to each user's field of interest. Therefore, the researcher of this study would like to propose a new searching technique...
Principal component analysis (PCA) is a well-known classical appearance-base method in face recognition. In the previous works, the preprocessing process significantly improved the recognition rate. Modular PCA and Wavelet PCA are the preprocessing processes of PCA, which increase the recognition rate of the original PCA. Modular PCA is suitable for the high- varied face database, while Wavelet PCA...
In this paper, we propose a mechanism for filtering incoming spam mails by generating spam mail prototypes using genetic algorithm. Firstly, words from e-mails are extracted and are categorized by their relating meaning into 7 groups. Then, we compose a string of chromosome having 7 genes, i.e., groups of words. Each gene, represented words in each group, is encoded into binary value. The genetic...
In this paper, the preprocessing process aimed to reduce size of input image by using wavelet transform before transformed image is sent to the process of PCA for recognition. We used ORL Face Databases from AT&T Laboratories Cambridge in the experiments. The results show that the 4th Order Symlets level 2 and level 3 improve the accuracy rate of recognition when compare among Haar wavelets, the...
