Self-reported inventories, e.g., Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI), as screening tests can elucidate the emotional valence; however, these tools are not designed for periodic monitoring in daily life. Moreover, positive affect is also hard to recognize without taking such self-reported inventories. Here we compared the indices of frontal alpha asymmetry (FAA) obtained from electroencephalography (EEG) data in the resting state and laterality index at rest (LIR) from near-infrared spectroscopy (NIRS) data. The Comfort Vector model (CVM) is another approach for using the feature value of prefrontal alpha wave fluctuation. In this paper, we discuss the applicability of these biomarkers for assessment of emotional valence. From experimental results from periodic NIRS and EEG recordings of two healthy subjects who participated for more than 4 weeks, feature values of FAA, LIR, and CVM were compared with BDI and STAI scores.","PeriodicalId":306012,"journal":{"name":"2018 IEEE International Conference on Cognitive Computing (ICCC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124802165","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}

Among others, one major objective is to identify the datasets studied in articles. Oftentimes, however, researchers do not explicitly cite the datasets used. Thus, we propose a profile-matching method strengthened by a neural network-based method to identify implicitly cited dataset entities based on the context.

We introduce a new class of Boolean Neural Networks (BNN), the all-implicants BNN, and show that this representation supports efficient update communication, better than the classical representation, based on truth tables.","PeriodicalId":306012,"journal":{"name":"2018 IEEE International Conference on Cognitive Computing (ICCC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129058112","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, certain observable phenomena, such as polarization, often emerge in online argumentation and deliberation, preventing constructive discourse. Accurately detecting the presence and intensity of polarization is important to determining if collective intelligence and crowd wisdom can be captured from online deliberation. In this paper, an innovative method of measuring polarization quantitatively in online argumentation is presented. Important polarization attributes such as homogeneity in groups, heterogeneity across groups, the number of poles, and the size of poles are identified to measure polarization in online argumentation. This new method uses our argumentation tool, Intelligent Cyber Argumentation System's (ICAS) cognitive computing component, a fuzzy logic engine, to derive the participant's agreement distribution. Then we apply an income polarization measurement from the field of economics [7] that we have modified and expanded for argumentation, on the agreement distribution to produce a polarization index value. We discuss why our method to measure argumentation polarization is a significant improvement over existing measurements for online argumentation polarization in terms of these identified attributes. We conducted empirical studies using ICAS that demonstrate that our method outperforms others that exist on our empirical data.","PeriodicalId":306012,"journal":{"name":"2018 IEEE International Conference on Cognitive Computing (ICCC)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122734198","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}

IAS are deployed in dynamic environments and connected with numerous devices of different types, and receive large sets of diverse data. They often receive new types of raw data that was not present in either training or testing data sets thus they are unknown to the learning models. In a dynamic environment, these unknown data objects cannot be ignored as anomalies. Hence the learning models should provide incremental guarantees to IAS for learning and adapting in the presence of unknown data. The model should support progressive enhancements when the environment behaves as expected or graceful degradations when it does not. In the case of graceful degradations, there are two alternatives for IAS: (1) weaken the acceptance test of data object (operating at a lower capacity) or (2) replace primary system with a replica or an alternate system that can pass the acceptance test. In this paper, we provide a combinatorial design—MACROF configuration—built with balanced incomplete block design to support graceful degradations in IAS and aid them to adapt in dynamic environments. The architecture provides stable and robust degradations in unpredictable operating environments with limited number of replicas. Since the replicas receive frequent updates from primary systems, they can take over primary system's functionality immediately after an adverse event. We also propose a Bayesian learning model to dynamically change the frequency of updates. Our experimental results show that MACROF configuration provides an efficient replication scheme to support graceful degradations in autonomous systems.","PeriodicalId":306012,"journal":{"name":"2018 IEEE International Conference on Cognitive Computing (ICCC)","volume":"247 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133747402","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}

While the traffic incidents detection problem can be treated as a time series classification task, there are not many attempts in this area and further investigations should be conducted. Recently, the Shapelet Transform algorithm has been proposed as a promising solution for time series classification. In this paper, we study the usage of Shapelet Transform in the field of traffic event detection. We first prove the applicability of the algorithm for automatic incident detection where it provides comparable performance to other techniques. In addition, we show how the Shapelet Transform algorithm can help in improving the detection by guiding the expert input in a cognitive approach. We test our approach using a real data set produced from road sensors of the M25 London Circular road. Results show an improvement comparing to using Shapelet Transform solely.","PeriodicalId":306012,"journal":{"name":"2018 IEEE International Conference on Cognitive Computing (ICCC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121817620","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}
