Cognitive load classification has seen a boost in popularity lately among the speech analysis community. A number of handmade feature based methods and purely machine learning based methods were presented in the last few years, all trained on a small number of established datasets. This paper presents results of several machine learning methods used on an original dataset of voice samples from a preliminary pilot study into effects of cognitive load. Basic arithmetic problems were presented to the participants with instructions to answer them verbally. Acoustic voice features were extracted from the recorded utterances and modelled using methods like Support Vector Machines and Neural Networks. The accuracies of classification are presented over several conditions for a binary classification task (low cognitive load vs. high cognitive load). The viability of the basic arithmetic task as a dataset for cognitive load classification is discussed. Lessons learned during the analysis are also discussed and present a basis for a stronger experiment design using basic arithmetic tasks in the future.
认知负荷分类最近在语音分析社区中越来越受欢迎。在过去的几年里,出现了许多基于手工特征的方法和纯粹基于机器学习的方法,所有这些方法都是在少数已建立的数据集上进行训练的。本文介绍了几种机器学习方法在认知负荷影响的初步试点研究中使用的语音样本原始数据集的结果。研究人员向参与者展示了一些基本的算术问题,并要求他们口头回答。从记录的话语中提取声学语音特征,并使用支持向量机和神经网络等方法建模。对二元分类任务(低认知负荷和高认知负荷)的分类准确率进行了比较。讨论了基本算法任务作为认知负荷分类数据集的可行性。本文还讨论了分析过程中的经验教训,并为将来使用基本算术任务进行更强的实验设计奠定了基础。

Temporal issues within modeling organizational systems are examined generally and with fuzzy cognitive maps. These maps give the opportunity to consider temporal factors when studying organizational models. The knowledge we gain about the system is useful when the aim is not to optimize time intervals in well-known and instrumented contexts, but also to discover the behavior of the system while different temporal factors are implemented by the management. We will present an adapted resolution for including these factors as key elements in organizational models with fuzzy cognitive map examples for middle and back office application.
建模组织系统中的时间问题一般和模糊认知图进行检查。这些图提供了在研究组织模型时考虑时间因素的机会。当我们的目标不是在已知的和仪器化的环境中优化时间间隔,而是在管理人员实现不同时间因素时发现系统的行为时,我们获得的关于系统的知识是有用的。我们将提出一种适应的解决方案,将这些因素作为组织模型中的关键要素,并提供用于中后台应用的模糊认知地图示例。

The design of a cognitive agent requires a behaviour control of actions and observations for exploring an unknown world. Typically, observations are influenced by a certain degree of randomness which can be modeled as probabilities. In our scenario we let a mouse explore a maze with walls, boundaries and a random portal. All observations are stored and managed in a so-called inner stage. As a decision problem, we want to be able to plan actions and to predict their resulting observations. In our approach we develop models of the inner stage based on concepts of probabilistic databases and their mapping to denormalized density matrices which are known from quantum mechanics. Density matrices provide a compact representation of the powerful but unwieldy many-world-semantics. We show that density matrices make the many-world-semantics feasible and are well suited to model the inner stage. We propose algorithms for learning and predicting action results.
认知代理的设计需要对探索未知世界的行为和观察进行行为控制。通常,观察结果受到一定程度的随机性的影响,这种随机性可以建模为概率。在我们的场景中,我们让一只老鼠探索一个有墙、边界和随机入口的迷宫。所有的观察都被存储和管理在一个所谓的内部阶段。作为一个决策问题,我们希望能够计划行动并预测其结果观察。在我们的方法中,我们基于概率数据库及其映射到量子力学中已知的非规范化密度矩阵的概念开发了内部阶段的模型。密度矩阵提供了强大但笨拙的多世界语义的紧凑表示。我们证明了密度矩阵使得多世界语义可行,并且非常适合于内部阶段的建模。我们提出了学习和预测动作结果的算法。

Assessment of wetlands by the methods of waterchemistry and bioindication 用水化学和生物指示法评价湿地
Pub Date : 2017-09-01 DOI: 10.1109/coginfocom.2017.8268283

Wetlands across Europe suffered the greatest damages of all habitats. The state of surface waters is determined by their ecological and chemical conditions. The ecological state is defined by the physico-chemical, hydromorphological and biological characteristics of the water, while the chemical state depends on the measured concentration of contaminants. The flora and fauna of stagnant water bodies and rivers respond sensitively and specifically to such impacts [1]. The Water Framework Directive (WFD) of the European Union (2000/60/EK) aims to provide solutions for this situation. In Hungary, the National Water Catchment Management Plans (NWCMPs) mean the tools for the implementation of the WFD. The pilot project was the assessment of Lake Riha which is a protected oxbow lake on the Mohács Island.
整个欧洲的湿地在所有栖息地中遭受的破坏最为严重。地表水的状况是由其生态和化学条件决定的。生态状态是由水的物理化学、水文形态和生物特性定义的,而化学状态则取决于所测量的污染物浓度。滞水水体和河流的动植物对这种影响作出了敏感而具体的反应[1]。欧盟的水框架指令(2000/60/EK)旨在为这种情况提供解决方案。在匈牙利,国家集水区管理计划(NWCMPs)是实施《世界水fd》的工具。这个试点项目是对位于Mohács岛上的一个受保护的牛轭湖——里哈湖的评估。

In knowledge-based societies new generations are flooded more and more intensely with narratives of inherited and newly generated knowledge, which is simply accessible for these generations, or to be acquired by them. Informatics and computer sciences are continuously developing new information-storage devices and a multitude of software more rapidly than ever. However, effective information search and processing require an information literacy which the new generations characteristically, and more and more demonstrably, do not have. National and international empirical research proves that the algorithmic thinking of the younger generations, which is indispensable for the world of informatics, is underdeveloped when it comes to the effective and productive use of digital tools. Moreover, the phenomenon of hyper attention invades the everyday life and the learning habits of the younger generation to a greater and greater degree. The essence of the HY-DE model is to aid the students' learning process with the help of the teacher's purposeful control of the phases of attention (hyper, mixed and deep attention). One aim of the present study is to introduce a new application of the HY-DE model, entitled Data-Structure Validator HY-DE model (DaSVa HY-DE). In the introductory phase, the DaSVa model focuses on how the HY-DE attention-divisions manifest themselves in webpage-search as well as in the information retrieval that it yields, and what the roles of the hyper, mixed, and deep attention modes are in the development of computational thinking and algorithmic skills. In the full hyper attention status the search for specified contents is carried out, focusing on webpages which consist of data organized in table or table-like structures. The automated and semi-automated conversion of the webpages however requires the decreasing of hyper attention leading to deep or mixed attention. The final result of this conversion process is/are well-structured table(s) suitable for automated data retrieval in spreadsheets, database management, and programming. The application of the original HY-DE model would lead us to its modification. In the advanced phase of the DaSVa HY-DE model the students can also experience how the webpages are designed and structured, how they support information and data retrieval, how successful the algorithmic based retrieval can be, and how the approach would lead students to the application of the theory of well-structured webpage design. With this model, from the hyper attention data collection status, through a deep and/or mixed attention algorithm building and data analyzing process, students would reach a higher-level hyper attention, the developer status.
在以知识为基础的社会中,新一代越来越强烈地淹没在关于继承和新产生的知识的叙述中,这些知识对他们来说很容易获得,或者他们需要获得。信息学和计算机科学正在以前所未有的速度不断开发新的信息存储设备和大量软件。然而,有效的信息搜索和处理需要新一代的信息素养,而这一点越来越明显。国内外的实证研究证明,年轻一代的算法思维是信息学世界不可或缺的,但在有效和富有成效地使用数字工具方面却不发达。此外,注意力过度集中的现象越来越多地侵入了年轻一代的日常生活和学习习惯。HY-DE模式的本质是通过教师有目的地控制注意阶段(超注意、混合注意和深度注意)来辅助学生的学习过程。本研究的目的之一是介绍HY-DE模型的一种新应用,称为数据结构验证器HY-DE模型(DaSVa HY-DE)。在入门阶段,DaSVa模型关注HY-DE注意力划分如何在网页搜索和信息检索中表现出来,以及超、混合和深度注意力模式在计算思维和算法技能的发展中所起的作用。在完全超关注状态下,对指定内容进行搜索,重点是由表格或类似表格结构的数据组成的网页。然而,网页的自动化和半自动化转换需要减少导致深度或混合注意的过度注意。转换过程的最终结果是结构良好的表,适用于电子表格、数据库管理和编程中的自动数据检索。原HY-DE模型的应用将导致我们对其进行修正。在DaSVa HY-DE模型的高级阶段,学生还可以体验到网页是如何设计和构建的,它们如何支持信息和数据检索,基于算法的检索有多成功,以及该方法如何引导学生应用结构良好的网页设计理论。通过该模型,学生将从超注意数据收集状态出发,通过深度和/或混合注意算法构建和数据分析过程,达到更高层次的超注意状态,即开发者状态。

Joint acquisition of word order and word referent in a memory-limited and incremental learner 记忆有限型渐进式学习者语序和指称的共同习得

Word learning in ambiguous contexts is a challenging task which is intertwined with the process of understanding the referential intentions of the speaker. It has been suggested that infant word learning occurs across learning situations and is bootstrapped by syntactic regularities such as word order. Simulation results from ideal learners suggest that it is possible to jointly acquire word order and meanings and that learning is improved as each language capability bootstraps the other. We study the utility of joint acquisition of simple versions of word order and word meaning in early stages of acquisition in a memory-limited incremental model. Comparing learning results in the presence and absence of joint acquisition of word order, word order regularities can quickly converge on real world statistics even using small datasets, relying on imperfect learned interpretations of word meanings, and even given wrong prior biases. Improvement in word learning results in the presence of joint acquisition of word order, however, were limited and only pronounced in the presence of high referential ambiguity and delayed syntactic bootstrapping where word order acquisition was slowed down through the use of priors.
歧义语境中的词汇学习是一项具有挑战性的任务,它与理解说话人的指称意图的过程交织在一起。有研究表明,婴儿的词汇学习发生在不同的学习情境中,并受到词序等句法规则的引导。理想学习者的模拟结果表明,共同习得语序和词义是可能的,并且在每种语言能力相互引导的情况下,学习能力得到了提高。在记忆有限的增量模型中,我们研究了在习得的早期阶段,语序和词义简单版本的联合习得的效用。比较存在和不存在词序联合习得的学习结果,即使使用小数据集,依赖于不完美的学习到的词义解释,甚至给出错误的先验偏差,词序规律也可以快速收敛于现实世界的统计数据。然而,在词序联合习得的情况下,单词学习结果的改善是有限的,并且只有在高度指称歧义和延迟句法引导的情况下才会出现,在这种情况下,语序习得通过使用先验而减慢。

We introduce an implementation of a GIS (Geographic Information System) research and development subsystem in the CV4SensorHUB (Computer Vision for SensorHUB) framework. The main concept is the usage and connection of open-access online databases such as OpenStreetMaps, Citybik.es, BKK Futár, MÁV Elvira and others. These databases cover different fields in the geographic domain. By connecting these databases with MapReduce paradigm and implementing smart algorithms, we are about to create an online tool where users could parametrize their trips around the town, using the live information and then visualize them on a map. For example, with the OpenStreetMaps it is possible to extract the maps, streets, POIs (point of interest), then with the Citybik.es we can get the live data about public bicycle sharing system, and with the BKK Futár we can access the live public transportation data, vehicles, timetables. In this paper, we focus on the data sources, the architecture with its common data model, and the main implementation steps of the system.

The main concept is the usage and connection of open-access online databases such as OpenStreetMaps, Citybik.es, BKK Futár, MÁV Elvira and others. These databases cover different fields in the geographic domain. By connecting these databases with MapReduce paradigm and implementing smart algorithms, we are about to create an online tool where users could parametrize their trips around the town, using the live information and then visualize them on a map. For example, with the OpenStreetMaps it is possible to extract the maps, streets, POIs (point of interest), then with the Citybik.es we can get the live data about public bicycle sharing system, and with the BKK Futár we can access the live public transportation data, vehicles, timetables. In this paper, we focus on the data sources, the architecture with its common data model, and the main implementation steps of the system.","PeriodicalId":212559,"journal":{"name":"2017 8th IEEE International Conference on Cognitive Infocommunications (CogInfoCom)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127746855","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}

In Hungary, the implementation and use of digital diaries in high schools facilitates the administration significantly and also allows features that are lacking by a paper-based diary. The half-year since the e-diary has been introduced in our school in the Kossuth Lajos Bilingual Technical Secondary School, gave many experiences and opinions among the teaching staff and these were gathered in a study presented in this article. These opinions and minds about the digital diary were analyzed through the results of an on-line survey filled by the teaching staff. The pre-set hypotheses were examined on the basis of the results of the questionnaire, and following this the conclusions were drawn.
在匈牙利,数位日记在高中的实施和使用,极大地促进了管理,也提供了纸质日记所缺乏的功能。科苏斯-拉霍斯双语中专学校引进电子日记半年来,在教学人员中积累了许多经验和意见,并在本文中进行了一项研究。通过一项由教师填写的在线调查结果,分析了这些对数字日记的看法和想法。根据问卷调查的结果对预设的假设进行检验,并得出结论。
