Perception verbs are the linguistic realization of human perceptual behavior. Based on the physiological stress response mechanism, this study deconstructs each English perception verb into a two-tuple which contains lexical core and lexical tentacle. The lexical core characterizes language features of perception verb and the lexical tentacle carries language information of perception verb. In this way, the process of perception verb cognition is activated by lexical core, along with lexical tentacle spreading. Language information like polysemy and collocation is described by lexical tentacle, more specifically, is described by word chains inside the lexical tentacle. The word chains record the linguistic information of perception verbs. And the numbers of word chains measure the lexical value of perception verbs. According to the lexical value, the perception verbs are ordered as see>feel>hear>smell > taste.
感知动词是人类感知行为的语言实现。基于生理应激反应机制,本研究将英语感知动词解构为包含词汇核心和词汇触手的二元组。词汇核表征感知动词的语言特征,词汇触手承载感知动词的语言信息。这样,感知动词的认知过程是由词汇核心激活的,词汇触手随之展开。多义、搭配等语言信息是通过词汇触手来描述的,更具体地说,是通过词汇触手内的词链来描述的。词链记录了感知动词的语言信息。词链的数量衡量感知动词的词汇价值。感知动词按词汇价值排序为:看>感觉>听>闻>尝。

In person re-identification (ReID) task, the variance between the samples are quite large, and there is no standard sample as a comparison. The current common method is to implement it as a classification task, which can get better results than the classical methods in verification task such as contrastive loss. However, the identification loss used in classification task only seeks the boundary of the classification, the intra-class distance between samples is still large so that it is insufficient for ReID task. In this paper, we consider to overcome these difficulties by proposing a joint loss with an identification loss and constrains of modeling the Euclidean distances between samples and their corresponding eigen data which is constructed by Principal Component Analysis method (PCA), we call it EigenPerson. The entire loss is formed in a linear combination. This work is mainly motivated by the center loss for face recognition problems, of which regularizations are restricted by a simultaneously learned center. We substitute the center with EigenPerson which we constructed offline as an auxiliary training sample. The learned model with our proposed method is evaluated on the benchmark of Market1501 and CUHK03 and achieve comparable results to those methods proposed in the same period.
在人员再识别(ReID)任务中,样本之间的差异很大,并且没有标准样本作为比较。目前常用的方法是将其作为一个分类任务来实现,在对比损失等验证任务中,该方法可以获得比经典方法更好的效果。然而,分类任务中使用的识别损失只寻求分类的边界,样本之间的类内距离仍然较大,不足以用于ReID任务。在本文中,我们考虑克服这些困难,提出了一种具有识别损失和约束的联合损失,该联合损失是由主成分分析方法(PCA)构建的样本与其对应的特征数据之间的欧几里得距离建模,我们称之为特征人。整个损失形成一个线性组合。本研究的主要动机是人脸识别问题的中心损失,该问题的正则化受到同时学习中心的限制。我们用离线构造的EigenPerson作为辅助训练样本来代替中心。用我们提出的方法学习的模型在Market1501和CUHK03的基准上进行了评估,并取得了与同期提出的方法相当的结果。

This study attempts to improve the forecasting accuracy of rolling grey model by applying Gaussian bare-bones differential evolution (GBDE) to optimize the weight of background value and number of data points used to construct a rolling-GM(1,1). Experimental results on two real time series forecasting problems show that the proposed GBDE-based rolling-GM(l,l) outperforms the traditional rolling-GM(l,l) in terms of fitting accuracy and forecasting accuracy.

Image-based obstacle avoidance has been studied for decades. One weak point of image-based approaches is that the performance usually depends on the lighting condition. That is, the performance can be very poor in dark environments. In this research, we investigate the possibility of the depth image-based approach for full-time indoor patrolling. As the first step, we consider a 3-class problem. Each depth image is classified as “danger” if some obstacle is too close, as “notice” if the obstacle is close, and as “normal” if there is no obstacle in the vicinity. The label of each depth image is defined based on the RGB image captured at the same time, and an AlexNet, which is a well-trained convolutional neural network, is retrained via transfer learning, and used for classification. In our primary experiment, we collected 102,776 image data in the Research Quadrangle of the University of Aizu. Test results show that the performance of the depth image-based approach is good during both day and night, and in most cases, it is better than the RGB image-based approach. This result can provide new insights when designing more practical full-time patrol robots.
基于图像的避障技术已经研究了几十年。基于图像的方法的一个弱点是性能通常取决于光照条件。也就是说,在黑暗的环境中,性能可能非常差。在本研究中,我们探讨了基于深度图像的方法用于全职室内巡逻的可能性。作为第一步,我们考虑一个3类问题。如果障碍物太近,每个深度图像被分类为“危险”,如果障碍物很近,则分类为“注意”,如果附近没有障碍物,则分类为“正常”。基于同时捕获的RGB图像定义每个深度图像的标签,并通过迁移学习对训练良好的卷积神经网络AlexNet进行重新训练,并用于分类。在我们的初步实验中,我们在会津大学的研究四合院收集了102776张图像数据。测试结果表明,基于深度图像的方法在白天和夜间都具有良好的性能,并且在大多数情况下优于基于RGB图像的方法。这一结果可以为设计更实用的全职巡逻机器人提供新的见解。

Predicting stock price has been a challenging project for many researchers, investors, and analysts. Most of them are interested in knowing the stock price trend in the future. To get a precise and winning model is the wish of them. Recently, Neural Network has been a prevalent means for stock prediction. However, there are many ways and different predicting models such as Convolutional Neural Networks (CNN), Recurrent Neural Network (RNN), Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU). In this paper, we propose a novel idea that average previous five days stock market information (open, high, low, volume, close) as a new value then use this value to predict, and use the predicted value as the average of the stock price information for the next five days. Moreover, we utilize Technical Analysis Indicators to consider whether to buy stocks or continue to hold stocks or sell stocks. We use Foxconn company data collected from Taiwan Stock Exchange for testing with the Neural Network Long Short-Term Memory (LSTM).

This study aims to extract symptom profiles and functional impairments of major depressive disorder from electronic health records (EHRs). A chart review was conducted by three annotators on 500 discharge notes randomly selected from a medical center in Taiwan to compile annotated corpora for nine depressive symptoms and four types of functional impairment. Named entity recognition techniques including the dictionary-based approach., a conditional random field model, and deep learning approaches were developed for the task of recognizing depressive symptoms and functional impairments from EHRs. The results show that the average micro-F-measures of the supervised learning approaches in extracting depressive symptoms is almost perfect (>0.90) but less accurate for the extraction of functional impairment.

Histogram of oriented gradients (HOG) is a highly important feature representation in computer vision for many applications such as objection detection. The HOG computes local histograms of oriented gradients of pixel luminance on a dense grid of uniformly spaced cells and normalized to be a feature vector. Its computational complexity is high, and its implementation on edge computing and embedded devices is challenging. This paper proposes a hardware software codesign strategy to redesign the HOG algorithm. Pipelining and hardware acceleration by FPGA are applied in the design to the performance improvement of HOG. The design is implemented on a heterogeneous computing platform and with high level synthesis techniques exploiting C-code to accelerate the design of hardware circuits. Our results of full HD images achieve 500 times speed-up compared with software implementation.
定向梯度直方图(Histogram of oriented gradients, HOG)是计算机视觉中一个非常重要的特征表示方法,可用于目标检测等领域。HOG在均匀间隔的密集网格上计算像素亮度方向梯度的局部直方图,并归一化为特征向量。它的计算复杂度很高,并且在边缘计算和嵌入式设备上的实现具有挑战性。本文提出了一种软硬件协同设计策略来重新设计HOG算法。在设计中采用流水线技术和FPGA硬件加速技术来提高HOG的性能。该设计在异构计算平台上实现,采用高级综合技术,利用c代码加速硬件电路的设计。与软件实现相比,我们的全高清图像的速度提高了500倍。

This paper presents a head motion detection and recognition study using a smart helmet for motorcycle rider which can potential be used for the analysis of behavior of motorcycle riders. The smart helmet is a full face motorcycle helmet integrated with an intelligent system embedded an Inertial Measurement Unit (IMU) sensor. In the analysis, the motions and the corresponding signals are assessed with the video footage with a data acquisition and visualization platform.

本文提出了一种基于智能头盔的摩托车驾驶员头部运动检测与识别方法,为摩托车驾驶员的行为分析提供了一种潜在的方法。智能头盔是一种全面摩托车头盔,集成了嵌入惯性测量单元(IMU)传感器的智能系统。在分析中,通过数据采集和可视化平台对视频片段的运动和相应的信号进行评估。我们引入了一种特征提取方法,从信号数据中提取最具判别性的特征,并将头部运动识别问题制定为基于机器学习的分类模型。实验结果表明,陀螺仪传感器数据比加速度计传感器数据更有利于头部运动识别,对不同头部运动的分类准确率在95.9% ~ 99.1%之间。

Although learning style is an important issue in STEM (Science, Technology, Engineering, and Mathematics), most of previous studies adopted questionnaire instrument to identify learning style. Therefore, this study proposes a concept framework of using artificial neural networks to identify students' learning styles based on the learning portfolio data in our designed education balance game with the Felder-Silverman learning style model (FSLSM). An education balance game is designed to train student's physical balance knowledge and collect their learning portfolio data. These portfolio data is input variables in support vector machine to identify students' learning style.
虽然学习风格是STEM (Science, Technology, Engineering, and Mathematics,科学、技术、工程和数学)中的一个重要问题,但以往的研究大多采用问卷调查的方法来识别学习风格。因此,本研究提出了一个概念框架,基于我们设计的费尔德-西尔弗曼学习风格模型(FSLSM)的教育平衡博弈中的学习组合数据,使用人工神经网络识别学生的学习风格。教育平衡游戏旨在培养学生的身体平衡知识,并收集他们的学习档案数据。这些组合数据是支持向量机的输入变量,用于识别学生的学习风格。
