Skin color based hand segmentation using skin color models shows poor performance in complex background where similar colors of the skin and non-uniform illumination exist. We propose a new method for hand segmentation by using an adaptive skin color model and the background information around the hand. Firstly, our method captures pixel values of the hand and the background then converts them into YCbCr color space. Secondly, skin and background Gaussian models based on the color space of CbCr are proposed. Lastly, these models are taken to segment the whole image respectively, and then required for the intersection. The main contribution of the paper is that the background information is taken into account to split image in reversed side to enhance the performance. Experimental results show that our method outperforms the method that uses the skin color model only.","PeriodicalId":128006,"journal":{"name":"2012 International Conference on Machine Learning and Cybernetics","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114142513","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}

However, less research work on classifier building on interval-valued problems has been conducted. It is promising to propose an approach to build classifier for interval-valued problems. In this paper, we propose a classification approach based on interval valued fuzzy rough sets. First, the concept of interval valued fuzzy granules are proposed, which is the crucial notion to build the reduction framework for the interval-valued databases. Second, the idea to keep the critical value invariant before and after reduction is selected. Third, the structure of reduction rule is completely studied by using the discernibility vector approach. After the description of rule inference system, a set of rules covering all the objects can be obtained, which is used as a rule based classifier for future classification. Finally, numerical examples are presented to illustrate feasibility and affectivity of the proposed method in the application of privacy protection.","PeriodicalId":128006,"journal":{"name":"2012 International Conference on Machine Learning and Cybernetics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114231364","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}

We analyze the model theoretically and simulate it on BA scale-free network. In comparison with the strongest robustness against cascading failures of the linear load-capacity model in the case of α = 0.5 , we find that the robustness of the network can reach stronger in the case of δ ≠ 1, which is a tunable parameter controlling the strength of the capacity of node in our model. The results show that the model is effective.

Vector quantization for a speech feature based on a codebook is a fundamental process to recognize the speech signal by DHMM. A codebook with fuzzy membership functions corresponding to each vector in the codebook will be first trained by genetic algorithms (GAs) through speech features. The trained fuzzy codebook is then used to quantize the speech features. Subsequently, the quantized speech statistical features are used to model the DHMM for each speech. Besides, all the speech features to be recognized will go through the fuzzy codebook for quantization before being fed into the DHMM model for recognition. Experimental results show that both the speech recognition rate and computation time for recognition can be improved by the proposed strategy.","PeriodicalId":128006,"journal":{"name":"2012 International Conference on Machine Learning and Cybernetics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115782829","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}

Many classifiers could not perform well in data imbalance cases. The major problem is that classifiers tend to ignore samples and accuracy of the minority class without regarding the higher cost of misclassification in this minor class. Therefore, pattern classification for imbalance data becomes a hot challenge to both academy and industry. In this paper, we propose an active learning method for imbalance data using a stochastic sensitivity measure (ST-SM) of Radial Basis Function Neural Network (RBFNN). A large ST-SM indicates the RBFNN is uncertain and yields a large output fluctuation around a particular sample. These samples yielding large ST-SM values are selected for adding to the training set in each turn. Empirically, samples with large output perturbation (i.e. large ST-SM) should be located near the classification boundary and is of great significance for the training of classifier. As for the imbalance characteristic of the data set, the ST-SM should be able to reduce the number of redundant samples being selected in the majority class, rebalance the sample distribution of the training set, and finally improve the performance of the classifier.","PeriodicalId":128006,"journal":{"name":"2012 International Conference on Machine Learning and Cybernetics","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116704245","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}

As a result, there are too few suspected smoke regions being recognized for an early fire alarm. In this paper, an early smoke detecting system that can efficiently extract dense smoke regions is proposed. Firstly, since the brightness in the areas that have dynamic texture is not constant, the residuals of optical flow are calculated to locate suspected smoke regions. A certain threshold of the increment of optical flow residuals is also used to distinguish smoke from other dynamic texture. Secondly, five features that can jointly represent a smoke area, including grayish color, chrominance decrease, edge energy decrease, optical flow orientation diffusion and circularity, are chosen by thorough experiments. Experimental results show that the proposed system can detect the smoke in early time and is robust to most kinds of interferences, especially other dynamic textures.","PeriodicalId":128006,"journal":{"name":"2012 International Conference on Machine Learning and Cybernetics","volume":"61 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113938186","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}

Learning to rank for information retrieval (LR4IR) employs supervised learning techniques to address this problem, and it aims to produce a ranking model automatically for defining a proper sequential order of related documents based on the query. The ranking model determines the relationship degree between documents and the query. In this paper an improved version of RankGP is proposed. It uses layered multi-population genetic programming to obtain a ranking function which consists of a set of IR evidences and particular predefined operators. The proposed method is capable to generate complex functions through evolving small populations.
