For deep learning applications, large numbers of samples are essential. If this condition is not met, effective features cannot be generated and overfitting occurs especially for the small datasets such as in medical applications. To address this issue, we propose a new dynamic ensemble merging algorithm that iteratively adjusts the weights of a convolutional neural network (CNN) ensemble's elements in an online manner. For given test instance, the proposed algorithm1, initially assigns equal weights to each of the classifiers and increases the weights of best k ones along iterations. Experiments that we conduct on a small deep learning dataset lead to promising ensemble results compared to its counterparts.
对于深度学习应用来说,大量的样本是必不可少的。如果不满足这个条件,就无法生成有效的特征,特别是对于医疗等小数据集,就会出现过拟合。为了解决这个问题,我们提出了一种新的动态集成合并算法,该算法以在线方式迭代调整卷积神经网络(CNN)集成元素的权重。对于给定的测试实例,所提出的算法1最初为每个分类器分配相等的权重,并随着迭代增加最佳k个分类器的权重。我们在一个小的深度学习数据集上进行的实验,与同类实验相比,得到了有希望的集成结果。

In this study, two-channel surface electromyogram (sEMG) signals were used to classify hand open/close with fingers. The bispectrum analysis of the sEMG signal recorded with surface electrodes near the region of the muscle bundles on the front and back of the forearm was classified by extreme learning machines (ELM) based on phase matches in the EMG signal. EMG signals belonging to 17 persons, 8 males and 9 females, with an average age of 24 were used in the study. The fingers were classified using ELM algorithm with 94.60% accuracy in average. From the information obtained through this study, it seems possible to control finger movements and hand opening/closing by using muscle activities of the forearm which we hope to lead to control of intelligent prosthesis hands with high degree of freedom.
本研究采用双通道肌电图(sEMG)信号对手指张开/闭合的手进行分类。在前臂前后肌束区域附近的表面电极记录的表面肌电信号的双谱分析,基于表面肌电信号的相位匹配,采用极限学习机(ELM)对表面肌电信号进行分类。研究对象为17人,男8人,女9人,平均年龄24岁。采用ELM算法对手指进行分类,平均准确率为94.60%。从本研究获得的信息来看,利用前臂的肌肉活动来控制手指的运动和手的开合似乎是可能的,我们希望能够实现对高度自由的智能假手的控制。

The use of computer technology in medical sciences is spreading with technology. The use of computers especially for imaging has become a third eye for physicians. In orthopedic surgeons, after simple roentgenograms for fracture detection, the use of computerized tomography and magnetic resonance has provided great convenience in the detection of fracture, typing, and therefore the appropriate treatment of the patient. The advancing technology has increased the quality of the images in the x-rayograms, reduced artifacts and enabled digital measurements. In this study, image processing and learning techniques were used to diagnose long bone fractures. The proposed artificial neural network has 89% success rate.

In industrial fabric productions, real time systems are needed to detect the fabric defects. This paper presents a real time defect detection approach which compares the time performances of Matlab and C++ programming languages. In the proposed method, important texture features of the fabric images are extracted using CoHOG method. Artificial neural network is used to classify the fabric defects. The developed method has been applied to detect the knitting fabric defects on a circular knitting machine. An overall defect detection success rate of 93% is achieved for the Matlab and C++ applications. To give an idea to the researches in defect detection area, real time operation speeds of Matlab and C++ codes have been examined. Especially, the number of images that can be processed in one second has been determined. While the Matlab based coding can process 3 images in 1 second, C++/Opencv based coding can process 55 images in 1 second. Previous works have rarely included the practical comparative evaluations of software environments. Therefore, we believe that the results of our industrial experiments will be a valuable resource for future works in this area.
在工业织物生产中,需要实时系统来检测织物缺陷。本文提出了一种实时缺陷检测方法,并对Matlab和c++编程语言的实时性进行了比较。在该方法中,使用CoHOG方法提取织物图像的重要纹理特征。采用人工神经网络对织物疵点进行分类。该方法已应用于圆型针织机上的针织物疵点检测。对于Matlab和c++应用程序,总体缺陷检测成功率达到93%。为了给缺陷检测领域的研究提供思路,对Matlab和c++代码的实时运行速度进行了测试。特别是,确定了一秒钟内可以处理的图像数量。基于Matlab的编码可以在1秒内处理3张图像,而基于c++ /Opencv的编码可以在1秒内处理55张图像。以前的工作很少包括软件环境的实际比较评估。因此,我们相信我们的工业实验结果将是这一领域未来工作的宝贵资源。

Estimating short-term power load is a fundamental issue in the power distribution system. Since short-term power load is related to many parameters such as weather conditions, and time. The aim of this study is to determine the relevant parameters in estimating short-term power load not only in order to decrease the computational cost, but also to achieve higher success rates. Furthermore, by using selected features the required memory, equipment and communication costs are also decreased in real time applications. Feature selection by extreme learning machine method was used in determining relevant features. The short-term power loads of two houses (one of them has a power generation capability) were used in tests and achieved results showed lower error rates were obtained by using less number of features.

Gaze analysis in dynamic environments has remained an unresolved problem due to the complexities that pertain to the detection and tracking of objects in the visual environment. This study provides a solution to the problem for face-to-face communication, in which the visual objects in the environment are faces. The application that has been developed for this purpose is able to detect and track faces in video steram, and it maps gaze locations to the images, thus allowing the user to detect gaze behavior, such as gaze aversion. The application is also capable of segmentation and diarization of speech syncronously with the vide o stream and eye movement overlay. It allows the user to annotate speech by speech act labels. The pilot studies reveal that the application provides acceptable accuracy values in the analysis, as well as significantly reducing the time for the analyses.
动态环境中的注视分析一直是一个未解决的问题,因为它涉及到视觉环境中物体的检测和跟踪的复杂性。本研究提供了一种解决面对面交流问题的方法,其中环境中的视觉对象是人脸。为此目的开发的应用程序能够检测和跟踪视频中的人脸,并将凝视位置映射到图像,从而允许用户检测凝视行为,例如凝视厌恶。该应用程序还能够与视频流和眼动覆盖同步分割和分割语音。它允许用户通过语音行为标签对语音进行注释。初步研究表明,该应用程序在分析中提供了可接受的精度值,并显着减少了分析时间。

The aim of this study was to detect sleep stages of human by using EEG signals. In accordance with this purpose, discrete wavelet transforms (DWT) and empirical mode decomposition (EMD) were separately used for feature extraction. Subcomponents of EEG signals obtained by the two methods were assumed as feature vectors. Statistical parameters were used to reduce dimension of feature vectors. The same statistical parameters were used to compare performance of methods related to DWT and EMD. K nearest neighborhood (kNN) algorithm was used in classification final feature vectors that obtained EEG segments related to different sleep stages. The classification accuracies for feature vectors based on DWT and EMD were obtained as 100% and 88.13%, respectively.

In this study, we will present a rule based fuzzy gesture recognition system where a user will interact with a spherical robot with hand gestures performed with a smart phone and the droid will respond by imitating this movements. In this context, we will take up the Gesture Recognition, Fuzzy Logic and Internet of Things (IoT) frameworks to construct such a Human-Machine Interface (HMI). In the proposed structure, the IoT collect the necessary IMU data from the smart phone for classification purposes while also providing the necessary data to the Sphero 2.0 droid. To recognize/classify the hand gestures performed with a smart phone, we will use and train fuzzy classifier. For proof of concept purposes, we have defined two hand gesture movements which are circular and linear gesture movement. The presented results clearly show that the performance of the fuzzy classifier is satisfactory even though each user has unique gesture characteristic (different magnitudes and velocities). Finally, we have also tested the proposed system in real-time with a user from whom we have not collected any IMU data. The presented results of the paper will show that the performance fuzzy logic based gesture recognition and interaction system is satisfactory.
在这项研究中,我们将提出一个基于规则的模糊手势识别系统,用户将与一个球形机器人交互,用智能手机执行手势,机器人将通过模仿这个动作来做出反应。在此背景下,我们将采用手势识别,模糊逻辑和物联网(IoT)框架来构建这样的人机界面(HMI)。在提议的结构中,物联网从智能手机收集必要的IMU数据用于分类目的,同时也向Sphero 2.0机器人提供必要的数据。为了识别/分类用智能手机执行的手势,我们将使用和训练模糊分类器。为了验证概念,我们定义了两种手势运动,即圆形手势运动和线性手势运动。结果清楚地表明,即使每个用户具有独特的手势特征(不同的幅度和速度),模糊分类器的性能也令人满意。最后,我们还用一个没有收集任何IMU数据的用户对所提出的系统进行了实时测试。本文的研究结果表明,基于模糊逻辑的手势识别交互系统的性能是令人满意的。

It offers easy-to-use tools for students and researchers working in the field of system analysis. This paper presents the motivation of its development, an overview of the uncertainty module of the toolbox and the relation with existing tools concerned to system analysis. One of the two main modules of the toolbox is introduced which deals with systems including parametric uncertainties. Analysis tools such as step response, Bode and Nyquist diagrams, interlacing property, root analysis on the first Riemann sheet and value set analysis have been studied overall the toolbox. Main motivation of FGATool lays on its ease of use without much knowledge on mathematical background and its user friendly graphical interface.
