In order to achieve the feature selection, these coefficients and their products are calculated through four spatial orientations, which gives 18 features. Two methods for feature selection are applied in order to select a smaller number of features. Bhattacharyya distance is used as a measure that quantifies separability in the feature domain. The obtained results show that using methods for feature selection reduce the number of features and make the image distortion classification more robust.","PeriodicalId":371831,"journal":{"name":"2018 14th Symposium on Neural Networks and Applications (NEUREL)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114249863","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}

Standard procedures for solving OOS are mostly manual and not scalable. This paper analyzes and proposes an automated and scalable solution for solving OOS problem inside commercial refrigerators. Small, low resolution cameras are placed inside refrigerators. Images taken with those cameras are analyzed with Faster R-CNN and Single Shot Multibox (SSD) models for object detection. Models were trained using transfer learning and their performances were analyzed and compared. After object detection, K-mean clustering algorithm is used to group objects on same shelves. Distance between objects on the same shelf determines if and where the OOS problem is present.","PeriodicalId":371831,"journal":{"name":"2018 14th Symposium on Neural Networks and Applications (NEUREL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124238488","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}

It is used in hospitals on a regular basis because FHR and UA tracings contain important information about fetal well-being. Despite the CTG’s long history of use (of almost 50 years), the benefits it brings to the daily practice remain unsatisfying. The interpretation of CTG recordings by obstetricians suffer from high inter- and intra-variability, while their computerized analysis still remains difficult. In this paper, we propose both supervised and unsupervised learning by deep Gaussian processes (DGPs) for classification of FHR tracings. In working with real FHR signals, we obtained promising results which demonstrate the potential of the DGPs methodology. Further, we showed that the performance of the DGPs was improved by utilizing corresponding UA signals.","PeriodicalId":371831,"journal":{"name":"2018 14th Symposium on Neural Networks and Applications (NEUREL)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114320192","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 this study we collected photoplethysmographic (PPG) signals with miniature, wearable pulse oximeters from dehydrated patients being treated in the emergency department of tertiary care medical center. We used a set of features based on the variable frequency complex demodulation (VFCDM) to track changes in the amplitudes of the PPG recordings in the heart rate frequency range over time. These features were fed to support vector machines (SVM) with radial basis function (RBF) kernel for automatic classification. The optimal overall accuracy for classifying dehydration, sensitivity and specificity were 67.91%, 72.77% and 64.31% respectively. These results are promising, and suggest that automatic distinction between dehydration and rehydration is potentially possible even in clinical setting.","PeriodicalId":371831,"journal":{"name":"2018 14th Symposium on Neural Networks and Applications (NEUREL)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128495594","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}

Experiments showed that the activity of honeybees outside the hive can estimated using an ultra-high definition video captured with UAV from distance of 10 meters.

In fishing and aquaculture industry one of the main challenges is production loss, that is, among the other things, caused by poor handling of the fish during operations such as crowding and delousing. This operations are very stressful for fish, and may trigger an increase in mortality, which is directly correlated with the production and profit loss. Because of this, improved solutions based on new technologies are being investigated, in order to decrease the risk of unnecessary stress, and improve the quality of production. One of the main parameters used for remote visual inspection of fish state is surface activity, which can be observed in a form of fish jumping and splashing. For that reason, in this paper, a novel algorithm based on using of Convolutional Neural Networks (CNNs) for splash detection is presented, which outperforms all existing algorithms based on local descriptors and linear classifiers. Using this approach we obtained splash detection accuracy of 99.9%.","PeriodicalId":371831,"journal":{"name":"2018 14th Symposium on Neural Networks and Applications (NEUREL)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126212402","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 lot of attention is paid on finding flexible solutions to this problem. To achieve flexibility, as a very challenging issue in improving the ability of generalization, deep networks have to deal with the stochastic effects of regularization. In this paper we propose a methodological framework for dealing with the stochasticity in regularized deep neural network. Basics of dropout as ensemble method for regularization are presented, followed by introducing new method for dropout regularization and its application in molecular dynamics simulations. Results from the simulation show that, the stochastic behavior cannot be avoided but we have to find way to deal with it. The proposed dropout method improves the state-of-the-art of applied deep neural networks on the benchmark dataset.","PeriodicalId":371831,"journal":{"name":"2018 14th Symposium on Neural Networks and Applications (NEUREL)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126587100","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}
