As the importance of lifelong learning and recurrent education has been emphasized in recent years, it can be argued that people must study for the rest of their lives. Many people, however, find it difficult to engage in and maintain learning behavior, and adequate learning support is required for people to participate in and maintain learning. We developed a learning support system based on the learner’s self-efficacy by the robot partner and explored its utility in this study to create an efficient learning support system by a robot partner. As a result, the proposed method’s effectiveness was demonstrated by the fact that the proposed learning support system increased the learner’s self-efficacy.
近年来,随着终身学习和经常性教育的重要性被强调,可以说,人们必须在余生中学习。然而,许多人发现很难参与和维持学习行为,人们需要足够的学习支持来参与和维持学习。我们开发了一个基于学习者自我效能感的机器人伙伴学习支持系统,并在本研究中探讨了其实用性,以创建一个高效的机器人伙伴学习支持系统。结果表明,所提出的学习支持系统提高了学习者的自我效能感,证明了所提出方法的有效性。

In this paper, we conduct an investigation of available time for automated external defibrillators (AED) in a Japanese city. In Japan, there are about 600,000 AEDs available in cities or towns, but only 4.9% of AEDs are used by bystanders when citizens suffer a sudden cardiac arrest. One reason of such low usage rate comes from their available time. Since many AEDs are installed by business owners, they are not available when their business is closed. We investigate the available time of AEDs in a Japanese city, Takatsuki, Osaka Japan. The number of AEDs that are available 24 hours can be increased by installing new AEDs in 24-hour convenience stores and a koban that is a small police station with policemen.
在本文中,我们对日本一个城市的自动体外除颤器(AED)可用时间进行了调查。在日本,城镇有大约60万个aed,但只有4.9%的aed是在市民发生心脏骤停时由旁观者使用的。使用率如此之低的一个原因是他们的可用时间。由于许多自动除颤器是由企业主安装的,因此当他们的业务关闭时,这些除颤器就不可用了。我们调查了日本大阪高摫市的aed可用时间。通过在24小时营业的便利店和配备警察的小型警察局安装新的除颤器,可以增加24小时可用的除颤器数量。

Intracerebral hematoma (ICH) is the cause of intracerebral hemorrhage. Acute enlargement of the ICH is high risk, and emergency surgical treatment is required. Therefore, prediction of ICH enlargement is essential to improve a survival rate and outcome. The purpose of this study is to find factors to predict the ICH enlargement with thick slice head CT images. We propose three kinds of feature extraction methods, (1) shape and texture features, (2) layered texture features, and (3) anatomical location features. In addition, we introduce an ICH enlargement prediction method using support vector machine (SVM) and feature selection. The experimental results showed that the angular second order moment of the texture feature was the most effective in predicting the ICH enlargement. By using this feature, we were able to predict the ICH enlargement with an accuracy of 75.7%. In addition, we found that normalization of the location and posture improved the prediction accuracy by 2.7% compared to that without normalization.
脑内血肿(ICH)是脑出血的病因。脑出血急性扩大是高风险,需要紧急手术治疗。因此,预测脑出血扩大对提高生存率和预后至关重要。本研究的目的是寻找预测头部厚层CT图像脑出血扩大的因素。我们提出了三种特征提取方法:(1)形状和纹理特征,(2)分层纹理特征,(3)解剖位置特征。此外,我们还引入了一种基于支持向量机和特征选择的ICH扩展预测方法。实验结果表明,纹理特征的角二阶矩是预测ICH扩大最有效的方法。通过使用这一特征,我们能够以75.7%的准确率预测脑出血扩大。此外,我们发现位置和姿势的归一化比未归一化的预测精度提高了2.7%。

In this paper, we develop an agent-based simulation model to avoid tourist concentration in a sightseeing area. Among main tourist destinations, the tourist concentration called "overtourism" becomes an issue for both of tourists and residents in the destinations. While spreading COVID-19 among sightseeing areas, tourist concentration should be avoided from the standpoint of the public health. We develop an agent-based simulation model to estimate the effectiveness of "congestion information at the destination" among tourists. The simulation results show that the congestion information is effective when only 30% of tourists follow the information to avoid the concentration in the major attractions in a sightseeing area.
本文建立了一个基于智能体的仿真模型,以避免旅游区的游客集中。在主要旅游目的地中,游客集中现象“过度旅游”成为游客和当地居民共同面临的问题。从公共卫生的角度来看,在观光区传播新冠病毒的同时,应避免游客集中。我们建立了一个基于agent的仿真模型来估计游客中“目的地拥堵信息”的有效性。仿真结果表明,当只有30%的游客遵循信息,以避免在观光区内主要景点集中时,拥堵信息是有效的。

This paper describes a relationship between singing experience and laryngeal movement obtained by DeepLabCut software to investigate whether singing improves swallowing function. First, we track the coordinates of the laryngeal region in videos captured swallowing movements by using DeepLabCut. Second, we remove the unusual outliers, and perform linear interpolation and the normalization for the obtained coordinates. Third, we extracted the features such as RMS, peak width and swallowing time. Finally, we did Welch's test to them against two groups: one with singing experience and the other without singing experience. As a result, we found the feature with a significant difference, and that the singing experience affected the swallowing time.
本文描述了DeepLabCut软件获得的唱歌体验与喉部运动的关系,以研究唱歌是否能改善吞咽功能。首先,我们通过使用DeepLabCut跟踪吞咽运动视频中喉区域的坐标。其次,去除异常异常点,对得到的坐标进行线性插值和归一化处理。第三,提取图像的RMS、峰宽、吞咽时间等特征;最后,我们对他们做了韦尔奇测试,把他们分成两组:一组有唱歌经验,另一组没有唱歌经验。结果,我们发现了有显著差异的特征,即唱歌的经历影响了吞咽时间。

This paper focuses on the analysis of behavior of immune cells for supporting diagnosis. The previous work has proposed to detect immune cells from medical images by recognition frequency space. However, the work has a problem that selects a region including multiple cells as a single cell. This paper aims to relax the problem by focusing the locality of cell shapes. Our proposal uses gradient-weighted class activation mapping (GradCAM) to capture locality characteristics of immune cells. The results shows that the densely inhabited immune cells are correctly selected. Our proposal has some issues that a cell is occasionally detected as multiple ones. We consider that this issue is can be solved by image processing techniques such as non-maximum suppression.
本文主要对免疫细胞的行为进行分析,以支持诊断。以前的工作提出了利用识别频率空间从医学图像中检测免疫细胞。但是,该工作有一个问题,即选择包含多个单元格的区域作为单个单元格。本文旨在通过聚焦细胞形状的局部性来缓解这一问题。我们的建议使用梯度加权类激活映射(GradCAM)来捕获免疫细胞的局部特征。结果表明,密集免疫细胞的选择是正确的。我们的建议存在一些问题,即一个单元偶尔会被检测为多个单元。我们认为这个问题可以通过非极大值抑制等图像处理技术来解决。

In this paper, we attempt to use a method of estimating a convergence point of the population to accelerate the search of the multi-objective chaotic evolution optimization. The movement vectors between generations have powerful information for inducing the search direction of the global optimum solution. We use these movement vectors that are composed of the non-dominated Pareto solutions to estimate a convergence point in which is the first Pareto front solution to enhance the search of multi-objective chaotic evolution algorithm. The estimated point is constricted by the movement vectors, and we use the estimated point to replace the population’s dominated solution to achieve the objective of enhancing the multi-objective chaotic evolution algorithm. We use hypervolume, generational distance, and inverted generational distance to evaluate our proposal. The result indicates that using an estimated point can accelerate the search of the multi-objective chaotic evolution algorithm.
在本文中,我们尝试使用一种估计种群收敛点的方法来加速多目标混沌进化优化的搜索。代与代之间的运动向量对于诱导全局最优解的搜索方向具有强大的信息量。我们使用这些由非支配Pareto解组成的运动向量来估计一个收敛点,该收敛点是第一个Pareto前解,以增强多目标混沌进化算法的搜索能力。估计点被运动向量压缩,用估计点取代种群的主导解,达到增强多目标混沌进化算法的目的。我们使用hypervolume,代际距离和倒代际距离来评估我们的建议。结果表明,使用估计点可以加快多目标混沌进化算法的搜索速度。

It is desired in a variety of fields to identify which variables are dependent, and variable dependence measures have been studied. The majority of such measures detect a linear or a certain range of nonlinear dependence between paired variables. To go beyond them, a method based on Neural Network Regression, Group Lasso, and Information Aggregation has been proposed in our past study. It can detect a wide range of nonlinear dependences among multi variables and discover the sets and representatives of the detected dependences. Its fundamental effectiveness has already been examined using synthesized artificial datasets containing a single dependence. For further evaluation in the present study, we conducted an experiment using those containing multi dependences. The proposed method succeeded in discovering the sets and representatives, and its performance was robust to data size and noise rate. The experimental results suggested that the proposed method works well for difficult tasks to handle multi dependences.
在许多领域都需要确定哪些变量是相关的,并且已经研究了变量依赖度量。大多数这类测量方法检测成对变量之间的线性或一定范围的非线性依赖关系。在过去的研究中,我们提出了一种基于神经网络回归、分组套索和信息聚合的方法。它可以检测多变量之间广泛的非线性依赖关系,并发现被检测到的依赖关系的集合和表示。它的基本有效性已经使用包含单一依赖的合成人工数据集进行了检验。为了在本研究中进一步评估,我们使用包含多依赖项的实验进行了实验。该方法成功地发现了集合和代表,并且对数据大小和噪声率具有鲁棒性。实验结果表明,该方法可以很好地处理复杂的多依赖项任务。

Stock Prediction Using Optimized LightGBM Based on Cost Awareness 基于成本意识的优化LightGBM库存预测
Pub Date : 2021-06-08 DOI: 10.1109/CYBCONF51991.2021.9464148

The application of machine learning in stock market prediction has generated widespread attention. This paper proposes a new method for short-term stock investment using optimized LightGBM based on cost awareness. By cost awareness here we define that the decision process is more aware of the false-positive errors, or is more aware of ‘fake chances’, and the cost for investment can be reduced. The main contribution of the research is to design an investment method for stock price prediction. Based on the principles of short-term investment and current quantitative investment research, we select a series of technical indicators that meet the requirements of this research to improve the reliability of the prediction results. We propose the concept of cost awareness to improve the accuracy of prediction. By comparing with the previous results, we demonstrated that the performance of the optimized model based on cost awareness could be improved significantly. we eventually examined and compared results with XGBoost and Random Forest, and found that LightGBM provides better performances in prediction accuracy, profitability, and risk control ability.
机器学习在股市预测中的应用已经引起了广泛的关注。本文提出了一种基于成本意识的优化LightGBM短期股票投资新方法。通过成本意识,我们在这里定义决策过程更了解假阳性错误,或者更了解“假机会”,从而降低投资成本。本研究的主要贡献在于设计了一种股票价格预测的投资方法。根据短期投资原理和目前定量投资研究的现状,我们选取了一系列符合本研究要求的技术指标,以提高预测结果的可靠性。为了提高预测的准确性,我们提出了成本意识的概念。通过与之前的结果比较,我们证明了基于成本意识的优化模型的性能可以得到显著提高。我们最终将结果与XGBoost和Random Forest进行了检验和比较,发现LightGBM在预测精度、盈利能力和风险控制能力方面具有更好的性能。

By comparing with the previous results, we demonstrated that the performance of the optimized model based on cost awareness could be improved significantly. we eventually examined and compared results with XGBoost and Random Forest, and found that LightGBM provides better performances in prediction accuracy, profitability, and risk control ability.","PeriodicalId":231194,"journal":{"name":"2021 5th IEEE International Conference on Cybernetics (CYBCONF)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114159692","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 recent years, osteotomy has been used as a treatment for osteomyelitis of the jaw. However, the extent of osteomyelitis that can be determined from preoperative images is ambiguous, which causes problems such as lengthy surgery. Therefore, it is necessary to estimate the resection area with high accuracy. In this study, we proposed a method that combines deep metric learning and anomaly detection to estimate the area of osteomyelitis before surgery. As a result of experiments, we were able to estimate the presence or absence of osteomyelitis with F value of 0.85.
近年来,截骨术已被用于治疗颌骨骨髓炎。然而,从术前图像可以确定的骨髓炎的程度是模糊的,这导致了诸如冗长的手术等问题。因此,有必要对切除面积进行高精度估计。在这项研究中,我们提出了一种结合深度度量学习和异常检测的方法来估计术前骨髓炎的面积。通过实验,我们可以估计是否存在骨髓炎,F值为0.85。
