However, the transmitted signal is subject to significant distortion by the very harsh environment, the medium, and the system itself. Despite this, data reaches its destination crisply or error-free. To achieve the high quality of error-free data, mechanisms that affect the quality of signal are addressed a priori and countermeasures are developed so that the potentially \"fuzzifiers\" are removed or \"de-fuzzified\". Here, the fuzzification-defuzzification process of the signal in real-time communication systems is addressed in the context of temporal fuzziness or fuzziness in the time domain. Temporal fuzzy factors that affect the operation of communication systems and their signal transmission are illustrated, analyzed, and the de-fuzzification process is discussed.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121455888","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, under certain conditions the backpropagation net classifier can produce nonintuitive, nonrobust and unreliable classification results. The backpropagation net is slower to train and is not easy to accommodate new data. To solve the difficulties mentioned above, an unsupervised/supervised type neural net, namely, ART-BP net, is proposed. The idea is to use a low vigilance parameter in ART2 net to categorize input patterns into some classes and then utilize a backpropagation net to recognize patterns in each class. Advantages of the ART2-BP neural net include (1) improvement of recognition capability, (2) training convergence enhancement, and (3) easy to add new data. Theoretical analysis along with a well testing model recognition example are given to illustrate these advantages.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121729141","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}

The performance of statistical methods utilizing the evaluation of the intensity of time-dependent fluctuations is compared with the results obtained by a layered artificial neural network model. The desired accuracy of the approximation by the neural network at the end of the learning phase has been estimated by analyzing the statistics of the learning data. The application of the obtained results to the analysis of actual anomaly data from a nuclear reactor showed that neural networks can identify the onset of anomalies with a reasonable success, while usual statistical methods were unable to make distinction between normal and abnormal patterns.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132400954","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}

The algorithm is designed for feedforward neural networks. Unlike conventional backpropagation, it does not require the suite of derivatives to be propagated from the top layer to the bottom one. Consequently, the amount of circuitry required for an analogue CMOS implementation is minimal. In addition, each unit in the network has its output fed back to itself across a delay element. Results from an HSPICE simulation of the 2.4 micron CMOS architecture are presented.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"54 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132535679","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}

Promising results have been reported elsewhere. A dynamic map-building technique for HLVQ is introduced, During learning, the creation of neurons follows a loose KD-tree algorithm. A criterion for the detection of the network weakness to match the topology of the training set is presented. This information is localized in the input space. When the weakness criterion is matched, a neuron is added to the existing map in a way that preserves the topology of the network. This new algorithm sets the network almost free of a crucial external parameter: the size of the neuron map. Furthermore, it is shown that the network presents highest classification score when employing constant learning rate and neighborhood size.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130021976","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}

The recognition of these signs using vision is a unique problem. The important aspects of this problem are that the object parameters such as scale and orientation are constantly changing with the motion of the camera. Also, new signs may appear at some time. In this case feature extraction algorithms are unable to meet the constraints of flexibility. Neural networks can be easily programmed for this task. A new learning strategy for self-organizing neural networks is presented. By iteratively subtracting the projection of the winning neuron onto the null space of the input vector, the neuron is progressively made more representative of the input. The convergence properties of the new neural network model are studied. Comparison results with standard Kohonen learning are presented. The performance of the network with respect to training and recognition of traffic signs is studied.<<ETX>>","PeriodicalId":209128,"journal":{"name":"Proceedings of 1994 IEEE International Conference on Neural Networks (ICNN'94)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134262380","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}
