An Exploratory Experiment of Layout Design Curriculum with Layered Grids Approach 分层网格布局设计课程的探索性实验
Kuei To Wang, Yao-Hua Lee
This exploratory study was conducted to understand importing layered grids as an assignment in editorial design courses, and to explore relevant variables which may affect curriculum performance. A double-grid layered experimental poster design assignment was assigned to sophomore design students. A self-evaluation questionnaire and expert group meeting followed for comparison analysis. Results showed that students with positive attitudes towards grid-based design assignments have stronger motivation to face challenges, and can solve the problem more distinctly and delicately. Those who consider grid designs as a constraint tend to take conservative and safer approaches towards designing. How to overcome students' psychological barriers and break away from the limitation of personal work habits are proposed as the essential goal for further curriculum reform. The study suggests that a variety of effective problem-solving approaches found from the experiment may be provided in advance, in the course description, to improve students' self-confidence synchronously.
本探索性研究旨在了解导入分层网格作为编辑设计课程的作业,并探讨可能影响课程绩效的相关变量。一个双网格分层的实验性海报设计作业被分配给设计专业大二的学生。随后进行自我评价问卷和专家组会议进行比较分析。结果表明,对网格设计作业持积极态度的学生面对挑战的动力更强,解决问题的能力也更清晰细致。那些认为网格设计是一种约束的人倾向于采取保守和安全的设计方法。如何克服学生的心理障碍,摆脱个人工作习惯的限制,是进一步课程改革的根本目标。本研究建议可以在课程描述中预先提供实验中发现的各种有效的问题解决方法,以同步提高学生的自信心。

Dong Xiaoxiao, Zhou Dongdai
Learning investment is considered to be an important predictor of academic achievement, and learning investment affects the realization of deep learning. The article uses the revised learning engagement scale and deep learning scale in an online learning environment to select high school students in science to conduct a questionnaire survey and collect data. The data is researched from three aspects: overall descriptive statistical analysis, correlation analysis between learning investment and deep learning, and regression analysis of learning investment and deep learning. The results show that (1) The overall level of student investment and deep learning is relatively high, but students' learning interests, the maintenance and cultivation of good learning habits, and their ability to transfer and use knowledge are lacking. (2) The student's investment in learning It has a significant positive correlation with deep learning, in which learning behavior investment has the most significant impact on deep learning, cognitive investment is the second, and emotional investment is the lowest. (3) Students' behavioral and cognitive investment can positively predict deep learning capabilities, and behavioral investment has the biggest impact, and emotional investment has no impact on deep learning. Based on the above research results, the article gives the strategies for improving students' deep learning ability.

Designs and Comparisons of Facial Direction Detection Technology with YOLO Based Deep Learning Networks 基于YOLO的深度学习网络面部方向检测技术的设计与比较
Min-Chi Lin, Shih-Chieh Lin, Y. Hwang, Chih-Peng Fan
By utilizing the deep learning model to develop the pedestrian facial direction classifier, in this paper, the proposed You only look once (YOLO)-based deep-learning technology is applied to analyze the images captured by camera to identify the facial directions of pedestrians. To enhance the training effect of mirror categories, the selected images are horizontally flipped to expand the datasets. To avoid misclassification of facial directions, the softmax scheme of the original YOLOv2 model is replaced with the logistic classifier used in YOLOv3, and the improved model is called YOLOv2_ logistic. By the same parameters on the webcam captured dataset, the experimental results show that the YOLOv2_logistic has the best performances on recall, precision, and mean Average Precision (mAP), which are 85%, 81%, 86.28%, respectively. The YOLOv3 tiny has the second performances, and its recall, precision, and mAP is 81%, 80%, 78.83%, respectively. In the frame per second (fps) test, the YOLOv3 tiny has the second best performance, and it reaches 30 fps on the Xavier platform. Although the facial direction detection performance of the YOLOv3 tiny model is slightly lower than that of the YOLOv2_logistic model, the performance of fps by the YOLOv3 tiny model is more than that by the YOLOv2_logistic model.
本文利用深度学习模型开发行人面部方向分类器,将提出的基于You only look once (YOLO)的深度学习技术应用于对摄像头拍摄的图像进行分析,识别行人的面部方向。为了增强镜像分类的训练效果,对选中的图像进行水平翻转,扩展数据集。为了避免面部方向的误分类,将原YOLOv2模型的softmax方案替换为YOLOv3中使用的logistic分类器,将改进后的模型称为YOLOv2_ logistic。实验结果表明,在相同的参数下,YOLOv2_logistic在查全率(recall)、查准率(precision)和平均查准率(mAP)方面表现最佳,分别为85%、81%和86.28%。YOLOv3 tiny的召回率(recall)为81%,准确率(precision)为80%,mAP为78.83%。在每秒帧数(fps)测试中,YOLOv3 tiny具有第二好的性能,在Xavier平台上达到30 fps。虽然YOLOv3微小模型的面部方向检测性能略低于YOLOv2_logistic模型,但YOLOv3微小模型的fps性能优于YOLOv2_logistic模型。

Performance Evaluation of Feature Encoding Methods in Network Traffic Prediction Using Recurrent Neural Networks 基于递归神经网络的网络流量预测特征编码方法性能评价
Yusuke Tokuyama, Ryo Miki, Y. Fukushima, Yuya Tarutani, T. Yokohira
Recurrent neural network method considering traffic volume, timestamp and day of the week (RNN-VTD method) is a promising network traffic prediction method because of its high prediction accuracy. The RNN-VTD method encodes timestamp and day of the week, which are categorical data, to numerical data using label encoding. The label encoding, however, gives magnitude to the encoded values, which may cause misunderstanding of recurrent neural network models, and consequently, the prediction accuracy of the RNN-VTD method may be degraded. In this paper, we investigate the effect of using one-hot encoding instead of label encoding for a feature encoding method in the RNN-VTD method. In the one-hot encoding, each input data is encoded to an k-dimensional 0--1 vector where k is the number of category types. Because the encoded data do not have magnitude, it is expected that the prediction accuracy of the RNN-VTD method is improved.
考虑流量、时间戳和星期几的递归神经网络方法(RNN-VTD方法)具有较高的预测精度,是一种很有前途的网络流量预测方法。RNN-VTD方法使用标签编码将时间戳和星期几这类分类数据编码为数值数据。然而,标签编码给编码值赋予了大小,这可能会引起递归神经网络模型的误解,从而降低RNN-VTD方法的预测精度。本文研究了在RNN-VTD方法中使用单热编码代替标签编码的一种特征编码方法的效果。在one-hot编码中,每个输入数据被编码为k维的0- 1向量,其中k是类别类型的数量。由于编码后的数据没有幅度,期望提高RNN-VTD方法的预测精度。

Effect of Virtual Channels for a Fault-Tolerant XY Routing Method with the Passage of Faulty Nodes 虚拟通道对有故障节点通过的容错XY路由方法的影响
Yota Kurokawa, Masaru Fukushi
The purpose of this paper is to reveal the effect of Virtual Channels (VCs) for our novel proposed fault-tolerant routing method which allows the passage of faulty nodes in Network on Chips (NoCs). Conventional fault-tolerant routing methods can be classified into two approaches; that is, (1) approach with VCs and (2) that without VCs. However, due to the large difference in the hardware amount required for the implementation, performance comparison has not been made between those approaches. VCs can be added for congestion mitigation; therefore, they can be added to even the methods based on (2). In this paper, we employ VCs in our method [6] which is based on (2) and make performance comparison between our method with Chalasani's method [2] which necessitates four VCs. Simulation results show that our method with four VCs can reduce average communication latency by about 96%, compared with Chalasani's method.
本文的目的是揭示虚拟通道(VCs)对我们提出的新的容错路由方法的影响,该方法允许芯片网络(noc)中的故障节点通过。传统的容错路由方法可以分为两种方法;即:(1)有风险投资的方法和(2)没有风险投资的方法。但是,由于实现所需的硬件数量差异很大,因此没有对这些方法进行性能比较。可以添加vc来缓解拥塞;因此,他们甚至可以添加到基于(2)的方法。在这篇文章中,我们使用VCs方法[6]基于(2),使我们的方法之间的性能比较与Chalasani方法[2]需要四个风投。仿真结果表明,与Chalasani的方法相比,采用4个vc的方法可以将平均通信延迟降低96%左右。

How Online Whiteboard Promotes Students' Collaborative Skills in Laboratory Learning 在线白板如何提高学生在实验室学习中的协作能力
T. Rojanarata
This work reports on the use of an online whiteboard in producing a collaborative and interactive report in laboratory learning at the Faculty of Pharmacy, Silpakorn University, Thailand. In this strategy, 166 students worked in groups of 8-9 to create experimental flow charts, to record data and to discuss results with friends on the board. Along with the students' activities, the instructors accessed the boards to monitor student progress and to provide feedback. From the questionnaires, most students reported that they were satisfied with using the tool and agreed that the learning activities were effective. While most of them had never used an online whiteboard before, they reported that the tool was not difficult to use and had useful and attractive features. Furthermore, they gained digital skills and teamwork skills from learning with the whiteboard. Therefore, online whiteboard can be used a tool to engage students in collaborative learning, active learning and formative assessment.
这项工作报告了在泰国Silpakorn大学药学院实验室学习中使用在线白板制作协作和互动报告的情况。在这个策略中,166名学生以8-9人为一组,制作实验流程图,记录数据,并在黑板上与朋友讨论结果。随着学生的活动,教师访问板来监控学生的进步,并提供反馈。从问卷调查中,大多数学生报告他们对使用工具感到满意,并同意学习活动是有效的。虽然他们中的大多数人以前从未使用过在线白板,但他们报告说该工具不难使用,并且具有有用和吸引人的功能。此外,他们还从白板学习中获得了数字技能和团队合作技能。因此,在线白板可以作为一种工具,让学生参与到协作学习、主动学习和形成性评估中来。
