It applies the minimum entropy method (MEM) to find the prominent point cell used for the phase calibration. After minusing the measured phase value of prominent point range cell from all the range bins belonged to the same echo, a well-focused ISAR image can be obtained by combining all the range bins. Compared to the PPP algorithm, the MPPP method can find the better prominent point unit utilized for the phase correction, which will lead to a more focused ISAR image after the phase compensation. The simulation result proves that the proposed approach can enhance the clarity and focusing of the ISAR image.","PeriodicalId":297027,"journal":{"name":"2013 Sixth International Symposium on Computational Intelligence and Design","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128746579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the channel state information(CSI) is known by the receiver, this scheme select the bit to demodulate based on the CSI, so it improve the channel usage. The demodulate threshold in this algorithm determines the demodulation order, hence it has great influence on system performance.

Compared with traditional single hidden layer feed forward neural networks, ELM executes with higher training speed and produces smaller error. Due to random input weights and hidden biases, ELM might need numerous hidden neurons to achieve a reasonable accuracy. A new ELM learning algorithm, which was optimized by the Firefly Algorithm (FA), was proposed in this paper. FA was used to select the input weights and biases of hidden layer, and then the output weights could be calculated. To test the validity of proposed method, a simulation experiments about the approximation curves of the SINC function was done.

In this paper, the wildcard is defines to match any one character in a sequence. Multiple wildcards form a gap. The length of a flexible gap is arbitrary. We design CLPM algorithm by use of cross list index structure to realize pattern matching with flexible wildcard gaps. The preprocessing algorithm is designed to initialize cross list so as to reduce searching space. In CLPM algorithm, the effective intervals is defined and computed based on the start positions of each sub pattern in each string, which help to obtain matching result set. Moreover, the approximate pattern matching is converted to short extract pattern matching. The contrast experiments are done based on DBLP tile data set. The results show that CLMP algorithm has better performance in the same fields.","PeriodicalId":297027,"journal":{"name":"2013 Sixth International Symposium on Computational Intelligence and Design","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133626754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to achieve these goals, we propose several key designs in implementing it. In this paper, we discuss the system architecture design at first. Then we introduce a simple but effective method to model 3D body prototypes. Based on models in Poser software, we segment them into layers and then do triangularizition to get triangular surfaces. As for garment modeling based on Spring-Mass model and physical try-on simulation, we propose a novel method based on uniform grid to detect collision. Store references of triangular surfaces into grids that they occupied and then calculate which grids a moving line of mass go through. Get triangular surfaces in these grids out and then judge whether the moving line intersects with them. It achieved fast detection in around 0.1% of time consuming by using linear searching. The performances of body modeling and try-on simulation are satisfying, and real-time responses could be achieved because of less complex computation and light-scale data transformation.","PeriodicalId":297027,"journal":{"name":"2013 Sixth International Symposium on Computational Intelligence and Design","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131093385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
