In this research work an ensemble of bagging, boosting, rotation forest, decorate and random subspace methods with 5 symbolic sub-classifiers in each one is presented. then a voting methodology is used for the final prediction. In order to decrease training time, before building the ensemble redundant features were removed using a slight filter feature selection method. A comparison with simple bagging, boosting, rotation forest, decorate and random subspace methods ensembles with 25 symbolic sub-classifiers is performed, as well as other well-known combining methods, on standard benchmark datasets. the proposed technique is shown to be more accurate than other related methods in most cases.
this paper presents an approach to derive critical points of a shape, the basis of a Reeb graph, using a combination of a medial axis skeleton and features along this skeleton. A Reeb graph captures the topology of a ...

this paper presents a simple method for detecting a psychological stressed or relaxed state by using only features extracted from the electrodermal activity signal. the signal is acquired with two small electrodes placed on the subject's left hand. Current methodologies used for stress detection provide recognition rates between 40% and 71% while using multiple physiological signals. there are some published papers that describe stress detection methods with satisfactory results without providing a numerical recognition rate. A method used in previous studies to induce a relaxed or stressed state is also presented, which generates similar results in laboratory conditions for different subjects. Also, a very strict signal acquisition protocol is used withthe purpose of minimizing artifacts caused by the bad electrode connection, environment or recording device.

this paper proposed an automatic clustering algorithm based on entropy for discovering the interest pattern over users' web log. We introduced the information entropy on the basis of clustering algorithm. Compared with traditional clustering algorithms, our method does not require any parameters specified by the end user. Meanwhile, it can discover the clusters in arbitrary shape and size. Experimental results over real-world dataset have fully demonstrated the advantages of our algorithm, which is effective in the problem of high-dimensional and non-informative priors patternrecognition.

Online social networks enhance user experience by connecting users with similar interests. Online friend recommendation is a rapid developing field in data mining. Current social networking services prescribe friends to users in light of their social graphs and mutual friends, which may not be the most proper to reflect a user's taste on friend selection in real lifetime. In this paper propose a system that recommends companions based on the daily activities of users. Here a semantic based friend recommendation is done based on the user's life styles such as posting, chatting, searching, commenting etc. By using text mining technique, we display a user's daily life as life archives, from which his/her ways of life are separated by using the Latent Dirichlet Allocation algorithm. At that point we discover a similarity metric to quantify the similarity of life styles between users as an incremental way, and ascertain user effect as far as ways of life with a similarity matching diagram. then calculate user impact ranking iterative matrix vector multiplication strategy in user incrementally, so that it would be versatile to vast scale frameworks. Ranking is mainly based on time spent on activities, profile information and feedback factor. At last, we incorporate a feedback component to further improve the proposal precision.
