Several criteria are given to assure that a unique equilibrium point of this model is existed, in addition, it is globally asymptotically stable via the properties of nonsingular M-matrices and definitions of stability. It is noteworthy that these conditions are an extension of existing works.

Deep learning has already made a great achievement in traffic sign detection. However, the camera on a car may capture a low resolution and blurry image in certain environments, which make it inaccurate for traffic sign detection. Therefore, we propose a method based on image super-resolution reconstruction for improving the detection rate of traffic signs. Firstly, a low-resolution image is transformed by CNN-based super-resolution network into a high-resolution one. Then, to meet the requirements of on-line processing, we use the generated super-resolution image as input for the detection network with 16 filters in this layer. At last, we separately trained two CNNs for super-resolution reconstruction and traffic sign detection, which reduce the processing time. Experimental results demonstrate that our model can achieve better performance than the existing methods for traffic sign detection.","PeriodicalId":6729,"journal":{"name":"2019 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"27 1","pages":"1208-1213"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90022447","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}

SEDS is a function which estimates system conditions such as voltage and current everywhere in the distribution system using limited measurement data. When outliers, which are not true values, are measured at the measurement points, JIT modeling and correntropy can be effective. Moreover, application of evolutionary computation techniques is necessary for the SEDS considering of a nonlinear characteristic of an objective function caused by equipment in distribution systems. Various evolutionary computation techniques including IBSODE have been applied to the SEDS. However, speed-up of calculation and high quality estimation results are required because of penetration of renewable energies. An evolutionary computation technique using multi-population and parallel distributed computing is one of solutions for the challenges. The proposed method is verified to speed up computation time and obtain higher quality estimation results than conventional methods.","PeriodicalId":6729,"journal":{"name":"2019 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"52 1","pages":"2714-2720"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89677936","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}

To investigate the effectiveness of the proposed method, in cooperation with medical institutions, we applied the proposed method to a total of 18 subjects (nine SAS patients and nine healthy subjects). The results derive the following implications: (1) SAS patients have WAKE with small biological vibrations, and the contribution of the corresponding low frequency components is high while the high frequency components, which is corresponded to large biological vibrations, is low contribution; (2) the proposed method could correctly detect SAS with 100% accuracy and non-SAS with 77.8% accuracy.","PeriodicalId":6729,"journal":{"name":"2019 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"50 1","pages":"550-556"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90082482","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}

Because of the limited amounts of the sample, an improper starting of the test could result in consuming of the evidence or unsuccessful analysis. Here we suggest a new process starting from NMR spectroscopy as NMR measurement is a non-destructive analysis, allowing other analysis methods after it.

An agent’s choice of the relevant subtask changes over time with the changes in the task environment state. Multi-agent Hierarchical Reinforcement Learning (MAHRL) provides an approach for learning to select the subtasks in response to the environment states, by using the joint task rewards to train various agents. When the joint task involves complex inter-agent dependencies, only a subset of agents might be capable of reaching the rewarding task states while other agents take precursory or intermediate roles. The delayed task reward might not be sufficient in such tasks to learn the coordinating policies for various agents. In this paper, we introduce a novel approach of MAHRL called Inter-Subtask Empowerment based Multi-agent Options (ISEMO) in which an Inter-Subtask Empowerment Reward (ISER) is given to an agent which enables the precondition(s) of other agents’ subtasks. ISER is given in addition to the domain task reward in order to improve the inter-agent coordination. ISEMO also incorporates options model that can learn parameterized subtask termination functions and relax the limitations posed by hand-crafted termination conditions. Experiments in a spatial Search and Rescue domain show that ISEMO can learn the subtask selection policies of various agents grounded in the inter-dependencies among the agents, as well as learn the subtask termination conditions, and perform better than the standard MAHRL technique.","PeriodicalId":6729,"journal":{"name":"2019 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"669 1","pages":"86-93"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76855837","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}
