Caption Generation is one of the fundamental tasks combining computer vision and natural language processing. To achieve this goal, neural networks are employed to implement a caption generation system. In this paper, we proposed a caption generation system combining a CNN-based object detection system and a language model with a recurrent neural network. Especially, a vector which is sent from the object detection system to the language model is generated using an attention mechanism. Attention visualization can help us to understand the system focuses on a part of the input image in generating a caption. In the experiments, we evaluate the performance of the proposed system and discuss the effects of the attention mechanism in the image caption. Especially, the attention contributes to the improvement of caption generation but the attention is uncorrelated to system interpretation.
标题生成是计算机视觉与自然语言处理相结合的基本任务之一。为了实现这一目标,采用神经网络实现标题生成系统。本文提出了一种结合基于cnn的目标检测系统和基于递归神经网络的语言模型的字幕生成系统。特别地,利用注意机制生成了从目标检测系统发送到语言模型的向量。注意力可视化可以帮助我们理解系统在生成标题时关注输入图像的一部分。在实验中,我们评估了该系统的性能,并讨论了注意机制在图像标题中的作用。特别是,注意力有助于改进标题生成,但注意力与系统解释无关。

The declining birth rate and aging of society in Japan have progressed remarkably, presenting great difficulties in recent years. Particularly, the burden of nursing care is a looming difficulty. To resolve it, attention must be devoted to preventing dementia in elderly people. We developed an activity program using communication robots in a cognitive function retention class for elderly community residents, and investigated their reactions and impressions. Results show that many elderly people were interested in activities that were performed along with the robot. They gave the impression that they are more fun than just doing tasks with people. Activities with direct talking to and interacting with robots must be developed.
近年来,日本的出生率下降和社会老龄化取得了显著进展,但面临着很大的困难。特别是,护理的负担是一个迫在眉睫的困难。为了解决这个问题,必须关注预防老年人痴呆症。我们在社区老年居民的认知功能保留课上开发了一个使用通信机器人的活动计划,并调查了他们的反应和印象。结果显示,许多老年人对与机器人一起进行的活动感兴趣。他们给人的印象是,他们比和人一起做任务更有趣。必须开发与机器人直接对话和互动的活动。

The game-based learning already is an important research area of the learning technology. The learning outcomes is a critical factor to evaluate the effectiveness of the learning game. Recent studies suggested giving students more immersive experiences can improve learning. In this paper, a new framework of designing the learning games for giving students more game immersive experience is proposed. The new framework is designed based on the considerations of players' habits and complexity of the learning materials. We can use this framework to create a blended playing environments with the arcade game and the serious learning game. Based on the pilot test and using for teaching, the new approach can give students more and better immersive experiences in playing the game and get a better learning result.

Multi linguistic problems such as auto-categorization is not an easy task. It is possible to train different models for each language, another way to do auto-categorization is to build the model in one base language and use automatic translation from other languages to that base language. Different languages have a bias to a language specific grammar and syntax and will therefore pose problems to be expressed in other languages. Translating from one language into a non-verbal language could potentially have a positive impact of the categorization results. A non-verbal language could for example be pure information in form of a knowledge graph relation extraction from the text. In this article a comparison is conducted between Chinese and Swedish languages. Two categorization models are developed and validated on each dataset. The purpose is to make an auto-categorization model that works for n'importe quel langage. One model is built upon LSTM and optimized for Swedish and the other is an improved Bidirectional-LSTM Convolution model optimized for Chinese. The improved algorithm is trained on both languages and compared with the LSTM algorithm. The Bidirectional-LSTM algorithm performs approximately 20% units better than the LSTM algorithm, which is significant.
像自动分类这样的多语言问题不是一件容易的事。可以为每种语言训练不同的模型,另一种进行自动分类的方法是用一种基本语言构建模型,并使用从其他语言到该基本语言的自动翻译。不同的语言对一种语言特定的语法和句法有偏见,因此会造成用其他语言表达的问题。从一种语言翻译成非言语语言可能会对分类结果产生积极的影响。例如,非言语语言可以是从文本中提取的知识图关系形式的纯信息。本文对汉语和瑞典语进行了比较。在每个数据集上开发并验证了两个分类模型。目的是建立一个自动分类模型,适用于非导入语言。其中一个模型是基于LSTM并针对瑞典语进行了优化的,另一个模型是针对汉语进行了优化的改进的双向LSTM卷积模型。改进算法在两种语言上进行了训练,并与LSTM算法进行了比较。Bidirectional-LSTM算法比LSTM算法的性能提高了约20%,这是非常显著的。

The purpose of this paper is to improve the user experience of C language development environment for novices, Hello C, which has been uniquely developed by our previous researches. To examine effective user experience, we conducted two kinds of experiments. The one was the experiment with the learning task of fixing syntax errors to evaluate the method to convey error message. This experimental result suggested that the indication of the error message like scripting language may be effective even C language learning. Next, we also conducted the other experiment with the learning task of fixing I/O errors and examined the effectiveness to convey the closeness to the correct answer. This experimental result suggested that utilizing the concept of small steps could help to acquire the skill of programming.
本文的目的是改善C语言初学者开发环境Hello C的用户体验,这是我们之前研究开发的独特的。为了检验有效的用户体验,我们进行了两种实验。一个是修复语法错误的学习任务实验,以评估传递错误信息的方法。这一实验结果表明,像脚本语言这样的错误信息提示,即使是C语言学习也可能有效。接下来,我们还对修复I/O错误的学习任务进行了另一个实验,并检查了传达接近正确答案的有效性。这个实验结果表明,利用小步骤的概念可以帮助获得编程技能。

Enterprises operate in fast-changing environments nowadays and experience the continuous need to adapt to changing circumstances and new strategical and technological developments. This observation impacts how enterprise information systems are analysed, designed, implemented and used. Focusing on the analysis and design phases, conceptual modelling methods in the field of enterprise architecture management experience a continuous evolution in research and practice. Existing methods are re-purposed for specific requirements, new methods are developed/evaluated in concrete industrial settings and coupling/integration techniques support holistic viewpoints. Nevertheless, current practices in the design and enactment of such methods, and more specifically their metamodels, are inefficient with respect to agile and iterative considerations. Within this paper, a novel design approach for modelling method engineering is discussed that builds on the notion of meta-models as conceptual structures. Syntactic and semantic operation on these structures aim to facilitate the design process following the design science research methodology. The approach is evaluated by introducing a case developed as part of the European research project GO0D MAN. In the context of the project an enterprise architecture metamodel has been designed, developed and deployed that supports an integrated viewpoint of conceptual model artefacts coupled with operational data visualisations to assess the effectiveness of design decisions.
如今,企业在瞬息万变的环境中运营,不断需要适应不断变化的环境以及新的战略和技术发展。这种观察影响了企业信息系统的分析、设计、实现和使用方式。企业架构管理领域的概念建模方法主要集中在分析和设计阶段,在研究和实践中经历了不断的发展。现有的方法被重新用于特定的需求,新方法在具体的工业环境中被开发/评估,耦合/集成技术支持整体观点。然而,当前设计和制定这些方法的实践,更具体地说,它们的元模型,相对于敏捷和迭代的考虑是低效的。在本文中,讨论了一种新的建模方法工程设计方法,该方法建立在元模型作为概念结构的概念之上。对这些结构进行语法和语义操作的目的是为了按照设计科学的研究方法促进设计过程。通过介绍作为欧洲研究项目GO0D MAN的一部分开发的一个案例,对该方法进行了评估。在项目的上下文中,已经设计、开发和部署了一个企业架构元模型,该模型支持概念模型工件的集成观点,并与操作数据可视化相结合,以评估设计决策的有效性。

From industrial viewpoint, the international conference has a significant economic impact for the region where the conference takes place. Participants at international conferences will spend more days than tourists or visitors for other purposes. Many different stakeholders are involved in the convention industry as it is an basic factor in promoting inbound tourism in Japan. Japanese governmental agency JNTO takes an important role of promoting to attract international conference. In this paper, 2427 samples are collected for evaluation effective elements to number of participants, which is include the name of the conference, venue, prefecture / city, the number of participants, etc., then, the chi-square test was adopted to clarify the relationship with participants. From the perspective of attracting international conferences, we analyzed the cities and venues where many foreign participants are coming. As a result, it become clear that there was an association among the participants, the venue and the host city. For international conference organizers, the choice of a venue and a host city is one of the most important factors for the success of the conference. Furthermore, it was found that the other factors considered were hardly related. On the other hand, it has also become clear that certain venues may exhibit outstanding performance.
从工业的角度来看,国际会议对会议举办地的经济产生了重大影响。参加国际会议的人将比游客或出于其他目的的游客花费更多的时间。许多不同的利益相关者都参与了会议产业,因为它是促进日本入境旅游的基本因素。日本政府机构JNTO在吸引国际会议方面发挥着重要的推动作用。本文选取2427个样本,对参会人数进行有效评价要素,包括会议名称、会场、地市、参会人数等,然后采用卡方检验澄清与参会人数的关系。从吸引国际会议的角度,我们分析了许多外国与会者来的城市和场地。因此,很明显,参与者、场地和主办城市之间存在一种联系。对于国际会议组织者来说,会场和主办城市的选择是会议成功与否的重要因素之一。此外,还发现其他考虑的因素几乎不相关。另一方面,也很明显,某些场馆可能会表现出色。

Grant-in-Aid for Scientific Research (KAKENHI) is the largest grants for academic research in Japan, and over two hundred billion yen is allocated for KAKENHI, annually. However, little is known about the kind of researchers who are recipients of KAKENHI and their achievements. In this paper, we investigated the number of KAKENHI grant recipients who received KAKENHI projects, the tendencies of their role, and their research achievements. The results suggested that researchers in humanities and social sciences tended to receive KAKENHI in collaborative projects. Also, there was no strong correlation between the number of recipients of KAKENHI projects and their research achievements; however, in some research fields, such as chemistry, a higher correlation was observed. Furthermore, some researchers were found to have received KAKENHI many times although their research achievements were few.
科学研究补助金(KAKENHI)是日本最大的学术研究补助金,每年拨给KAKENHI的资金超过2000亿日元。然而,对于KAKENHI的接受者和他们的成就,人们知之甚少。在本文中,我们调查了KAKENHI资助接受者接受KAKENHI项目的人数、他们的角色倾向以及他们的研究成果。结果表明,人文社会科学研究人员在合作项目中倾向于获得KAKENHI。此外,KAKENHI项目的受助人数与其研究成果之间没有很强的相关性;然而,在一些研究领域,如化学,观察到更高的相关性。此外,还发现一些研究人员虽然研究成果很少,但多次获得KAKENHI。

Unlike the traditional networking infrastructure, the software defined network (SDN) separates the network control function from the data transmission function. The SDN covering a large geographical area requires multiple controllers, and controller provisioning has a significant impact on the performance of entire network. In this paper, a novel load balancing scheme is proposed to effectively solve the dynamic controller provisioning problem (DCPP) for SDN. The proposed scheme employs progressive harmony search and K-means clustering of the switches to maximize the accuracy of finding the optimal solution and minimize the search time. The proposed scheme is evaluated by computer simulation in terms of accuracy and execution time of load balancing, and it turns out to be superior to the existing schemes.
与传统的网络基础设施不同,软件定义网络(SDN)将网络控制功能与数据传输功能分离开来。覆盖较大地理区域的SDN需要多个控制器,控制器的配置对整个网络的性能影响很大。为了有效解决SDN网络的动态控制器配置问题,提出了一种新的负载均衡方案。该方案采用渐进式和声搜索和开关的K-means聚类,以最大限度地提高寻找最优解的准确性和最小化搜索时间。通过计算机仿真对该方案进行了负载均衡精度和执行时间的评价,结果表明该方案优于现有方案。

In this paper, a novel load balancing scheme is proposed to effectively solve the dynamic controller provisioning problem (DCPP) for SDN. The proposed scheme employs progressive harmony search and K-means clustering of the switches to maximize the accuracy of finding the optimal solution and minimize the search time. The proposed scheme is evaluated by computer simulation in terms of accuracy and execution time of load balancing, and it turns out to be superior to the existing schemes.","PeriodicalId":136474,"journal":{"name":"2019 8th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121438640","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 learn the skill of self-regulated learning (SRL), it is important for learners to implement "metacognition of SRL" that monitors and controls SRL. However, we think there are two crucial difficulties in metacognition of SRL for non-experts of SRL skills: cognitive overload and the implicit process of metacognition of SRL. Our aim is to design a learning environment to alleviate these difficulties and motivate the metacognition of SRL. To focus learners' attention on the metacognition of SRL, we have designed a learning environment in which a learner is given an assignment to play the role of mentor to a pseudo mentee (non-human) to improve SRL. In the assignment, the learning environment provides representations about the mentee's learning situations and learner's utterances. We have designed a learning environment that allows learners to connect these representations and utterances to motivate the metacognition of SRL. This has been designed to alleviate cognitive load and promote the verbalization of SRL.
为了学习自我调节学习的技能,学习者需要实现“自我调节学习元认知”,对自我调节学习进行监控和控制。然而,我们认为对于非语言技能专家来说,语言元认知存在两个关键困难:认知超载和语言元认知的内隐过程。我们的目标是设计一个学习环境来缓解这些困难,并激发SRL的元认知。为了将学习者的注意力集中在SRL的元认知上,我们设计了一个学习环境,在这个学习环境中,学习者被分配一个任务,扮演一个导师的角色,以提高SRL。在作业中,学习环境提供了关于学员的学习情境和学习者的话语的表征。我们设计了一个学习环境,允许学习者将这些表征和话语联系起来,以激发SRL的元认知。这是为了减轻认知负荷,促进语言的语言化。
