However, integrating the state-transition feature into the CRF model always results in a long training time. It is believed that there is no study focusing on this problem. Therefore, this paper proposes a path-constrained Viterbi algorithm to substitute the use of the state-transition feature, where the core idea involves pruning the paths (or state transitions) that does not exist in real-world data in the Viterbi decoding process. The proposed method is simple but effective. The experimental results obtained for four natural language processing (NLP) tasks, i.e., Chinese word segmentation (CWS), Named Entity Recognition (NER), text chunking, and part-of-speech (POS) tagging, demonstrate that the proposed method achieved performance close to that using state-transition feature, and hence saving as much as half the training time in total.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130469349","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 the linear lambda calculus with non-linear first-class continuations, a value is handled linearly, meaning it can be used once and only once; however, a continuation can be duplicated many times. From the viewpoint of the CurryHoward isomorphism, the calculus is considered as dual of the usual lambda calculus without first-class continuation. And this paper proposes an inference algorithm and a system for the type inference. The linear lambda calculus with non-linear first-class continuations is more limited than the linear lambda calculus without first-class continuations. Therefore, the paper manages both of the two calculis using the type inference. It introduces a modal variable in the types to substitute the linear modality. During type inference, modal variables are instantiated.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129302279","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}

This paper is aimed at breaking this point and facilitating feature space transformations directed by an intelligent Minkowski Weight K-means clustering algorithm through hybrid dissimilarity measure (iMWK-HD). The proposed hybrid dissimilarity measure assign weights to features based on Minkowski distance and Cosine dissimilarity, which can extend, shrink and rotate feature space so that the performance of WK-means clustering can be improved. In iMWK-HD, a new optimization objective function is designed based on minimizing the hybrid dissimilarity. Using the new objective function, it derives new updating rules for the iterations in the clustering procedure. Experimental results on UCI datasets demonstrate that iMWK-HD is superior to the three existing clustering algorithms, i.e. iK-means, iWK-means and iMWK-means. In addition, the proposed algorithms are immune to irrelevant features in cluster subspace.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115295995","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}

Therefore, combining with Canny operator to detect the edge of radar scanning image, an improved radar image interpolation algorithm is proposed. Finally, experiments are conducted and compared with the nearest neighbor interpolation algorithm, bilinear interpolation algorithm and FEOI algorithm. The experimental results show that the proposed algorithm is superior to the above algorithms and can effectively reduce aliasing and blurring and obtain the interpolated image with good visual effect.
