For these purposes, we propose the multi-objective optimization with Voronoi diagram and genetic algorithm (MOVGA). As for the maximization of the amount of generated heat, we predict the amount by using regression equation of multiple linear regression analysis and formulate it as the set partitioning problem (SPP) to maximize the prediction value. As for the minimization of waste collection distances, we formulate it as the multi-Weber problem. To solve these two problems, we use MOVGA, which has the seeds of the Voronoi diagram as a gene. As a result of the survey using data of 2015 year of Chiba northwest bay area, in the case of 3 facilities it was found that the calorific value increased enough to cover the power of 4,205 households (converted to housing complex) per year despite the increase of 3% t-km per year.","PeriodicalId":139434,"journal":{"name":"2019 IEEE 11th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129776979","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}

Hence, there is a possibility that it might be difficult to select an adequate vehicle in metaphor generation. The purpose of this research is to construct a metaphor database based on a literature corpus and use the database to build a metaphor generation support system. At first, sentences including metaphors were extracted from a literature corpus. The extracted sentences were analyzed using dependency parsing in order to construct a metaphor database for the metaphor generation system. The system outputs candidate vehicles from a given topic and its expressed features by searching the sentences including the topic or the features in the database. Furthermore, an experiment was conducted to evaluate the usability of the system. In the experiment, participants were asked to generate a sentence including a metaphor from a shown image with or without the system. Third-party evaluation was conducted to evaluate the metaphors generated in the experiment. The results seem to suggest the efficiency of the system.","PeriodicalId":139434,"journal":{"name":"2019 IEEE 11th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"2008 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125624884","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}

There are many types of security countermeasures. Adversarial examples and their defense methods, in particular, have been well-studied in recent years. An adversarial example is designed to make neural networks misclassify or produce inaccurate output. Audio adversarial examples are a type of adversarial example where the main target of attack is a speech-to-text transcription neural network. In this study, we propose a new defense method against audio adversarial examples for the speech-to-text transcription neural networks. It is difficult to determine whether an input waveform data representing the sound of voice is an audio adversarial example. Therefore, the main framework of the proposed defense method is based on a sandbox approach. To evaluate the proposed defense method, we used actual audio adversarial examples that were created on Deep Speech, which is a speech-to-text transcription neural network. We confirmed that our defense method can identify audio adversarial examples to protect speech-to-text systems.","PeriodicalId":139434,"journal":{"name":"2019 IEEE 11th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134291212","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}

Two fusion configurations were used for the experiments, early fusion CNN classifier and late fusion CNN classifier. The early fusion configuration of the CNN classifier takes combined two face images as input for verification. The advantages of early fusion configuration are no heavy changes in the classifier architecture and only the first layer that have a different filter size. The late fusion configuration of the CNN classifier formed by creating dual CNN network for extracting the deep features of each face image and classify the kinship relationship using two fully-connected layers. The softmax and angular softmax (a-softmax) loss are used for evaluating the network in the training process with fine-tuning strategy. The classifier then evaluated using large-scale FIW (Family in the Wild) kinship verification dataset consists of 1,000 family and 11 different kinship relationship. Experiments using the 5-fold configuration on FIW dataset show that the ensemble of fusion CNN classifier produces comparable performance with several different state-of-the-art methods.","PeriodicalId":139434,"journal":{"name":"2019 IEEE 11th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"46 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124666937","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}

Carpineto et al. have proposed a term expansion method based on FCA (Formal Concept Analysis), while Rogers et al. have proposed another term expansion method based on LDA (Latent Dirichlet Allocation). In this paper, we take the notion of weighted term similarity measures in FCA, and examine its effectiveness used for term expansion. We also study the effectiveness of some correlation measures in the field of association rule mining. We perform some experimental study on the effects of the proposed term similarity measures in term expansion using two short text corpora. The experimental results show that those weighted term similarity measures, when choosing an appropriate weight value, outperform the prior methods.","PeriodicalId":139434,"journal":{"name":"2019 IEEE 11th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124611953","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}

Specifically, we adopt a recent time-series averaging method, Euclidean barycenter-based DTW barycenter averaging, to obtain effective mean templates while preserving intra-user variability among reference samples. Then, we estimate the local stability of the mean template set using multiple matching points that detect significant distorted trajectories in the warping paths of DTW. Subsequently, to boost discriminative power in the verification phase, we use the LS-DTW distances that incorporate the local stability sequence as the weights for the cost function of DTW warping between the set of mean templates and a test sample.

It is necessary to provide learning support corresponding to the understanding degree of each learner to improve learning process efficiency. For this purpose, this study develops a procedure to predict the achievement level of learners at the end of the class and classify them. A Multi-Context Recurrent Neural Network (MCRNN) is used for predicting achievement level and classifying learners. By providing additional education for the learners who are classified as a low degree by the proposed method, it is expected to be able to take countermeasures for not becoming dropout in early stage. In this study, numerical experiments are executed to verify the usefulness of the proposed method. To gather enough number of learners' data, this study generates the learners' growth process data that used as training and test data of MCRNN.
