Challenge in sketch recognition is the variation and imprecision present in sketch. Free drawing styles of sketching make it difficult to build a robust sketch recognition system. This paper proposes a novel recognition approach that can recognize primitive shapes, as well as combinations of these primitives. The approach is independent of stroke order, number, as well as invariant to size and aspect ratio of sketch. Feature string is used to represent primitives. We defined a similarity measure on these feature strings that counts common substrings in two input strings, which is referred to as the string kernel in the field of kernel methods. Support vector machine(SVM) is then trained with labeled examples to handle the task of classification. The experiment on hand drawn digital circuit diagrams shows that our system can recognize sketching efficiently and robustly.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121245211","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}

Each individual contains two states, the attractive state and the repulsive state. In order to refrain from the shortcoming of premature convergence, a two point reversal crossover operator is defined and in the repulsive process each particle is repelled away from some inferior solution in the current tabu list to fly towards some promising areas which can introduce some new information to guide the swarm searching process. DE adjusts the mutation rate F and the crossover rate CR adaptively, taking account of the different distribution of population. TPDE maintains the diversity of population and improves the global convergence ability. It also improves the efficiency and success rate and avoids the premature convergence.

Wide attention has been attracted by academic circles for its less computation cost and better generalization ability, and it became a new research priorities gradually. A simple geometric interpretation of Twin SVM is that each hyperplane is closest to the points of its own class and as far as possible from the points of the other class. This method defines two nonparallel hyper-planes by solving two related SVM-type problems. Localized Twin SVM is a classification approach via local information which is based on Twin SVM, and has been proved by experiments having a better performance than conventional Twin SVM. However, the computational cost of the method is so high that it has little practical applications. In this paper we propose a method called Fast Localized Twin SVM, a classifier built so as to be suitable for large data sets, in which the number of Twin SVMs is decreased. In Fast Localized Twin SVM, we first use the training set to compute a set of Localized Twin SVMs, then assign to each local model all the points lying in the central neighborhood of the k training points. The query point depending on its nearest neighbor in the training set can be predicted. From empirical experiments we can show that our approach not only guarantees high generalization ability but also improves the computational cost greatly, especially for large scale data sets.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133022164","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}

A manifold learning algorithm such as isometric feature mapping algorithm (ISOMAP) was firstly employed to perform nonlinear feature extraction for initiating the training set, and its effect on a subsequent classification was then tested in combination with learning algorithms such as support vector machines. The gait data including young and elderly participants were analyzed, and the experimental results demonstrated that the generalization performance of ISOMAP-SVM is an evidently improved performance compared to the traditional classifier for recognizing young-elderly gait patterns. Our work suggested that manifold learning algorithm can find the intrinsic low-dimensional manifold embedding in high-dimensional gait data, and obtain the `true' nonlinear gait features associated with human gait function change for improving the gait classification performance.
