The concept is based on several layers of prediction models. One aim of this approach is to eliminate time lag, which is more severe in longer prediction horizons. Thus, the prediction accuracy of the algorithm might be increased, even for longer prediction horizons. The second goal is to create new, potentially good predictors that could be obtained by combining existing predictors. The effectiveness of the proposed model is illustrated in several examples of two-layer networks. In the first layer, a specific linear/non-linear prediction model is used. In the second (correction) layer, an extreme learning machine is used, due to its rapid learning capabilities. In almost all experiments, the proposed method has reduced the time lag and improved the accuracy of the method.","PeriodicalId":331222,"journal":{"name":"2016 13th Symposium on Neural Networks and Applications (NEUREL)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123050394","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 proposed approach can be used to reconstruct missed measurements caused, for example, by measurement equipment failure. In this way an accurate and complete set of measurements can be obtained.

The aim of this paper is to investigate possibilities of the radial basis function (RBF) ANNs to be applied for modeling of mechanical characteristics of RF MEMS capacitive switches, relating the switch geometry parameters and the actuation voltage. The achieved results obtained by the developed RBF neural model are compared with the results from the earlier developed multilayer perceptron (MLP) neural model. Moreover, effectiveness and accuracy of these two ANN models are analysed. The results confirm the efficiency of the both modelling approaches.","PeriodicalId":331222,"journal":{"name":"2016 13th Symposium on Neural Networks and Applications (NEUREL)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129890167","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}

Part of the success can be attributed to good image representations that are extracted using convolutional layers of the network. In this paper we consider convnets from the perspective of feature extraction for remote sensing image classification. We analyze the impact of convolutional feature extraction as well as the role of feature learning on the ability of features to discriminate between land cover classes. The quantitative analysis is based on measuring both classification accuracy and discriminative ability of features. For the latter we use Fisher discriminant analysis and show that features extracted using convolutional layers with random weights have significant discriminative ability and result in a reasonable baseline for remote sensing image classification, which suggests that convolutional feature extraction itself is an important ingredient of feature extraction in convnets. Using learned convnets for feature extraction further improves discriminative ability of features.","PeriodicalId":331222,"journal":{"name":"2016 13th Symposium on Neural Networks and Applications (NEUREL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130673044","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 users have a tendency to provide positive feedbacks much more than the negative ones, the system that does not use methods to deal with class imbalance provides poor prediction of the contents that the user does not like to watch. Thus undesirable contents can often be recommended, which is perceived by users as bad recommendation. The probability of bad recommendations can be significantly decreased if the information about class imbalance is incorporated into the machine learning algorithm. However, this improvement comes at expense of degraded prediction of contents that user likes to watch; thus the quality of recommendations is decreased. In addition to learning algorithm, the choice of performance metric that is maximized influences user perception of the system performance. In this paper, it is shown that using the adjusted G-mean instead of G-mean metric can increase the quality of recommendations provided by the system based on neural network, without significant increase in the probability of bad recommendations. This further results in the increase of the recommendation diversity and, consequently, in the increase of user satisfaction.","PeriodicalId":331222,"journal":{"name":"2016 13th Symposium on Neural Networks and Applications (NEUREL)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127211567","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 order to increase the usage of some smaller and cheaper, but on the other hand less precise sensor solutions, it is necessary to incorporate some signal processing techniques for noise reduction. Nowadays soft computing techniques such as neural networks are widely used in many signal processing applications and provide very good results. In this paper, an approach to noise reduction by using autoassociative neural networks is described. The main idea is to use more precise, therefore more expensive sensor, for the network training, and afterward use this network for less precise and cheaper sensor signal processing. So, when the network is formed, it is possible to use less precise sensor and use the network for noise reduction. This would ensure noise reduction in the less precise sensor signal. With this signal processing tool, less precise sensors could be used in desired applications. When comparing the results obtained by using autoassociative neural networks with results obtained by using digital filters, the obvious advantage is that neural networks do not bring delay into the system like filters do. All described simulations and data processing are performed in Matlab and Simulink.","PeriodicalId":331222,"journal":{"name":"2016 13th Symposium on Neural Networks and Applications (NEUREL)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116150080","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}
