In order to tackle energy poverty and increase energy efficiency in energy systems, a hybrid energy system including wind, hydrogen and fuel cells is proposed to supplement to the main power grid. Wind energy is firstly converted into electrical energy while part of the generated electricity is used for water electrolysis to generate hydrogen for energy storage. Hydrogen is used by fuel cells to convert to electricity when electrical energy demand peaks. An analytical model is developed to coordinate the operation of the system involving energy conversion between hydrogen, electrical and mechanical forms. The proposed system is primarily designed to meet the electrical demand of a rural village while the energy storage system can meet the discrepancy between intermittent renewable energy supplies and fluctuated energy demands so as to improve the system efficiency. Genetic Algorithm (GA) is used as an optimization strategy to determine the operational scheme for the multi-vector energy system. In this work, case studies are carried out based on actual measurement data. The test results have confirmed the effectiveness of the proposed methodology and maximizing the wind energy consumption locally. This is an alternative to battery energy storage and can be widely used in wind-rich rural areas.","PeriodicalId":6729,"journal":{"name":"2019 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"7 5 1","pages":"3172-3176"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77407774","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}

Conventional online parameter estimation algorithms, which are used for system identification, require a restrictive condition of persistence of excitation (PE) for the estimates to converge to the true parameters. Some recent works have shown that collaborative system identification using multiple agents can relax the PE condition to a milder condition of collective persistence of excitation (C-PE) for parameter convergence. The C-PE condition implies that the PE condition is cooperatively satisfied by all the agents through sharing information between neighbors using a connected graph architecture, where each individual agent does not require to satisfy the PE condition separately. The proposed work designs a novel collaborative parameter estimator dynamics, which with the help of integral-like component ensures parameter convergence under a further slackened condition; coined as collective Initial Excitation (C-IE). The C-IE condition is an extension of the concept of initial excitation (IE), which is recently proposed in the context of parameter estimation in adaptive control. It has been already established that IE condition is significantly less restrictive than PE. The current work generalizes the concept of IE in a multi-agent settings, where information sharing through connected graph guarantees consensus parameter convergence under the C-IE condition. It can be argued that C-IE condition is milder than all of the other above mentioned conditions of PE, C-PE and IE. Simulation results further validate the efficacy of the proposed estimation algorithm.","PeriodicalId":6729,"journal":{"name":"2019 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"4 1","pages":"1285-1291"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77643044","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 common practice for working with categorical features is to use an encoding method to transform the discrete values into numeric representation. However, numeric representation often neglects the innate structures in categorical features, potentially degrading the performance of learning algorithms. Utilizing the numeric representation could also limit interpretation of the learned model, such as finding the most discriminative categorical features or filtering irrelevant attributes. In this work, we extend the iterative hard thresholding (IHT) algorithm to quantify the structure of categorical features. The empirical evaluation of the proposed structured hard thresholding algorithm is based on both real and synthetic data sets in comparison with the original hard thresholding algorithm, LASSO and Random Forest. The results demonstrate an improved performance over the original IHT.","PeriodicalId":6729,"journal":{"name":"2019 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"19 1","pages":"2541-2547"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91280633","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}

This paper presents an alternative Neural Network training algorithm based on OS-ELM, which is able to perform learning online while dynamically modifying the weights of previously learned samples in order to decrease the importance of old samples learned over time.

This study constructed a GAN-based generative model for F0 contours that can stably generate more-various F0 contours that fit the statistical characteristics of the training data. We tested the classification rate of four kinds of emotions in the F0 contours generated from five kinds of generative models. We also evaluated the averaged local density of the generated F0 contours to represent the variety of the generated F0 contours.
