In this paper, we propose a news web page classification method (WPCM). The WPCM uses a neural network with inputs obtained by both the principal components and class profile-based features (CPBF). Each news web page is represented by the term-weighting scheme. As the number of unique words in the collection set is big, the principal component analysis (PCA) has been used to select the most relevant features for the classification. Then the final output of the PCA is augmented with the feature vectors from the class-profile which contains the most regular words in each class before feeding them to the neural networks. We have manually selected the most regular words that exist in each class and weighted them using an entropy weighting scheme. The fixed number of regular words from each class will be used as a feature vectors together with the reduced principal components from the PCA. These feature vectors are then used as the input to the neural networks for classification. The experimental evaluation demonstrates that the WPCM method provides acceptable classification accuracy with the sports news datasets.","PeriodicalId":310128,"journal":{"name":"Proceedings of the International Joint Conference on Neural Networks, 2003.","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123233390","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}

Al-Shaikhli","doi":"10.1109/IJCNN.2003.1223931","DOIUrl":"https://doi.org/10.1109/IJCNN.2003.1223931","url":null,"abstract":"We have continued testing the hypothesis of visual feature-binding by synchronization in/spl gamma/ monkey visual cortex. Current support for this hypothesis comes from recent results demonstrating local synchrony among rhythmic or stochastic /spl gamma/-activities (30-90Hz) - including their perceptual modulation - and decoupling of /spl gamma/-activity among neural groups representing figure and background. On the other hand, /spl gamma/-synchrony in primary visual cortex is restricted to few millimeters, which challenges the binding-by-synchronization hypothesis for larger cortical distances. But we found that this restriction is due to extended traveling /spl gamma/-waves, randomly altering their directions. Thus, across intermediate distances, phase continuity of these waves may still support coding of object continuity. Finally, across large distances we observed cortico-cortical interactions among low frequency signals and the envelopes of amplitude-modulated /spl gamma/-signals. We discuss potential mechanisms of near-, medium- and far-range cooperativity on the basis of spike-coding model networks. They include two types of inhibitory feedback loops generating local /spl gamma/-activities and low-frequency modulations, respectively. In conclusion, we propose that the binding-by-synchronization hypothesis, initially restricted to synchrony of oscillatory /spl gamma/-signals, be extended to more general forms of signal coupling, including near-range phase synchrony (coherence) between /spl gamma/-activities, medium-range phase continuity of /spl gamma/-waves, and far-range coupling involving low-frequency signals and envelopes of /spl gamma/-signals.","PeriodicalId":310128,"journal":{"name":"Proceedings of the International Joint Conference on Neural Networks, 2003.","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121601640","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}
