Integrated Transfer Learning Based on Group Sparse Bayesian Linear Discriminant Analysis for Error-Related Potentials Detection 基于组稀疏贝叶斯线性判别分析的集成迁移学习误差相关电位检测
Jing Wang, Tianyou Yu, Zebin Huang
Brain-computer interface is a technology that is helpful for these people with dyspraxia or strokes to obtain the ability to communicate with others or control devices again. However, due to the brain signal collected by the system has terrible quilty, the error decision is often made by the BCI system, which hinders the development of the technology. Therefore, detecting the error from the BCI system holds a great significance by error-related potential (ErrP) generated when erroneous feedback from the system is found by the subject. In this paper, we propose an integrated transfer learning based on Group Sparse Bayesian Linear Discriminant Analysis (ITL_GSBLDA) to detect ErrPs. In this way, the Group Sparse Bayesian Linear Discriminant (GSBLDA) has better performance with the help of transfer learning. The experiment has been finished with the dataset of Kaggle competition. In the experiment, sensitivity, specificity, and Area Under Curve (AUC) are used to evaluate the performance of the decoder. Finality, the results are 71.49% sensitivity, 66.49% specificity, and 0.7624 AUC when using the signal features and meta-feature. And in this condition, our decoder surpasses the 5th place in the competition.
脑机接口是一种帮助有运动障碍或中风的人重新获得与他人交流或控制设备的能力的技术。然而,由于BCI系统采集到的脑信号质量差,导致BCI系统经常做出错误的决策,阻碍了该技术的发展。因此,通过被试发现系统的错误反馈时产生的错误相关电位ErrP (error-related potential)来检测BCI系统的错误具有重要意义。本文提出了一种基于群稀疏贝叶斯线性判别分析(ITL_GSBLDA)的集成迁移学习方法来检测errp。这样,在迁移学习的帮助下,组稀疏贝叶斯线性判别(GSBLDA)具有更好的性能。实验使用Kaggle竞争数据集完成。在实验中,使用灵敏度、特异性和曲线下面积(AUC)来评估解码器的性能。最后,当使用信号特征和元特征时,结果灵敏度为71.49%,特异性为66.49%,AUC为0.7624。在这种情况下,我们的解码器在比赛中超过了第五名。

An improved binocular LSD_SLAM method for object localization 一种改进的双目LSD_SLAM目标定位方法
Jianwei Ren
Vision sensors can simulate human eyes to process visual scenes. Vision-based object localization technology has been widely studied and applied in some fields such as autonomous driving. SLAM technology can estimate the surrounding environment and locate itself in real time without prior knowledge. The existing binocular vision positioning SLAM has problems such as insufficient positioning accuracy, high data requirements and high computational cost. This paper proposes an improved binocular LSD_SLAM method with census transform, which purpose is to reduce the requirement for the initial value and optimize the localization accuracy. Experiments in several office scenarios show that the proposed method is improved on Average Precision and Average Recall, and its computing cost still needs to be improved.

Code Plagiarism Detection Method Based on Code Similarity and Student Behavior Characteristics 基于代码相似度和学生行为特征的代码抄袭检测方法
Qiubo Huang, Xuezhi Song, Guozheng Fang
We proposed a plagiarism detection approach based on code similarity and student behavior characteristics in educational scenarios. The traditional plagiarism check is based on the code only, which enables that students can escape inspection by modifying a small amount of code. We proposed that if the behavioral characteristics of students when submitting code can be considered, the suspected plagiarism can be more accurately identified. We proposed the concept of code similarity concentration (SCD) with reference to the Gini coefficient idea. SCD can reflect the similarity distribution between all the codes submitted by a student and others' codes. A large value of SCD means that a student's codes are always the most similar to the codes of some particular classmates. In addition, we also extracted other features to help detection. Finally, we classify the plagiarism detection problem as a binary classification problem and use LightGBM to make decisions. The experimental results show that the accuracy is close to 99% and f1-score is close to 98%.
我们提出了一种基于代码相似度和学生行为特征的教育场景抄袭检测方法。传统的抄袭检查只基于代码,这使得学生可以通过修改少量代码来逃避检查。我们提出,如果可以考虑学生提交代码时的行为特征,可以更准确地识别出涉嫌抄袭的行为。我们借鉴基尼系数的思想,提出了代码相似度浓度的概念。SCD可以反映学生提交的所有代码与其他代码之间的相似度分布。SCD值越大,意味着学生的代码总是与某些特定同学的代码最相似。此外,我们还提取了其他特征来帮助检测。最后,我们将抄袭检测问题归类为二元分类问题,并使用LightGBM进行决策。实验结果表明,该方法的准确率接近99%,f1-score接近98%。

Residual Adaptive Mask Generative Adversarial Network for Image Raindrop Removal 残差自适应蒙版生成对抗网络去除图像雨滴
Zihui Jia, Yuesheng Zhu
Single image raindrop removal is an extremely challenging task since the raindrop regions of various shapes and sizes are not given and the background information of the occluded regions is completely lost for most part. In this paper, a novel two-stage residual adaptive mask generative adversarial network (RAM-GAN) is developed for single image raindrop removal, in which the raindrop regions can be automatically detected and a restored image without raindrops is generated. Moreover, the residual adaptive mask block (RAMB) structures and residual dense adaptive mask modules (RDAMM) are proposed to be the main components constructing the network. The proposed RAMB structure can serve as a feature selector which adaptively enhances the effective information and suppress the invalid information. Each block is processed into two branches: soft mask branch and trunk branch. A mask is generated by the soft mask branch to softly weigh the features processed by the trunk branch. In addition, RDAMM, the residual densely connected module based on RAMB structure, is proposed to maximize the information flow among different blocks and guarantee better convergence. Our experimental results have demonstrated that our method can effectively remove raindrops while well preserving the image details, which outperforms the state-of-the-art methods quantitatively and qualitatively.
单幅图像的雨滴去除是一项极具挑战性的任务,因为没有给出各种形状和大小的雨滴区域,遮挡区域的背景信息在很大程度上是完全丢失的。本文提出了一种新的两阶段残差自适应掩模生成对抗网络(RAM-GAN),用于单幅图像的雨滴去除,该网络可以自动检测雨滴区域并生成无雨滴的恢复图像。提出残差自适应掩码块(RAMB)结构和残差密集自适应掩码模块(RDAMM)作为网络的主要组成部分。所提出的RAMB结构可以作为自适应增强有效信息和抑制无效信息的特征选择器。每个块被加工成两个分支:软掩模分支和主干分支。软掩码分支生成掩码,对主干分支处理的特征进行软加权。此外,提出了基于RAMB结构的残差密连接模块RDAMM,使不同块之间的信息流最大化,保证更好的收敛性。实验结果表明,该方法可以有效地去除雨滴,同时很好地保留图像细节,在数量和质量上都优于目前最先进的方法。

Optimal fatigue life design of double row angular contact ball bearings by an adaptive RL-BFGS algorithm 基于自适应RL-BFGS算法的双列角接触球轴承疲劳寿命优化设计
Qing Shao, Tao Xu, Yoshino Tatsuo
An adaptive RL-BFGS (ARL-BFGS) algorithm was proposed for fatigue life design to speed up the convergence and obtain the global optimal solution under the circumstances of fewer optimization times. Fatigue life is one of the most essential criteria for the optimal design of double row angular contact ball bearings. The contact angle was selected as a design parameter besides the basic geometric parameters. The design constraints considering the manufacturing and mounting situations were processed by a penalty function. Three different constraint non-linear optimization models were established for the optimal dynamic and static load capacity, and their weighted form. The bearing model 3210 was optimized successfully to prove the correctness and effectiveness of the proposed algorithm. The overall performance of the ARL-BFGS algorithm was checked by the comparative experiments of different optimization methods and different bearing models. The result showed that the dynamic load capacity and static load capacity of the optimized bearing series 32 are approximately 60% and 30% higher than the standard value in Rolling Bearing Handbook by using the ARL-BFGS algorithm, respectively. The weighted form of the dynamic and static load capacity was also optimized to provide more selection for designers.
提出了一种自适应RL-BFGS (ARL-BFGS)算法用于疲劳寿命设计,以加快收敛速度,在优化次数较少的情况下获得全局最优解。疲劳寿命是双列角接触球轴承优化设计的重要指标之一。除了基本几何参数外,还选择了接触角作为设计参数。考虑制造和安装情况的设计约束通过惩罚函数进行处理。建立了三种不同约束的最优动、静态承载能力非线性优化模型,并给出了它们的加权形式。对3210轴承模型进行了优化,验证了算法的正确性和有效性。通过不同优化方法和不同轴承模型的对比实验,验证了ARL-BFGS算法的整体性能。结果表明,采用ARL-BFGS算法优化后的轴承系列32的动载能力和静载能力分别比滚动轴承手册中的标准值高出约60%和30%。对动、静载能力的加权形式也进行了优化,为设计人员提供了更多的选择。

Fatigue life is one of the most essential criteria for the optimal design of double row angular contact ball bearings. The contact angle was selected as a design parameter besides the basic geometric parameters. The design constraints considering the manufacturing and mounting situations were processed by a penalty function. Three different constraint non-linear optimization models were established for the optimal dynamic and static load capacity, and their weighted form. The bearing model 3210 was optimized successfully to prove the correctness and effectiveness of the proposed algorithm. The overall performance of the ARL-BFGS algorithm was checked by the comparative experiments of different optimization methods and different bearing models. The result showed that the dynamic load capacity and static load capacity of the optimized bearing series 32 are approximately 60% and 30% higher than the standard value in Rolling Bearing Handbook by using the ARL-BFGS algorithm, respectively. The weighted form of the dynamic and static load capacity was also optimized to provide more selection for designers.","PeriodicalId":113564,"journal":{"name":"2020 IEEE International Conference on Artificial Intelligence and Computer Applications (ICAICA)","volume":"60 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116434872","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}

Risk Assessment of Logistics Projects based on BP Neural Network: A Case Study on African Countries 基于BP神经网络的物流项目风险评估——以非洲国家为例
Dafeng Xu, Tongtong Xu, Chunmei Liu, Jingbo Yang
In recent years, China's direct investments in Africa have grown substantially, making the risk analysis of direct investments by logistics companies increasingly important. Many specialised agencies in the world measure the national investment risk. However, their assessments only analyse the political and economic environment of each country without emphasising the importance of risk assessment in terms of logistics projects. This study fills the gap by presenting the risk assessment of logistics projects in 10 major African countries where China has the highest foreign direct investment. On the basis of existing research, an artificial neural network is mainly used to establish China's risk index system for African logistics projects and a macro early warning model for the investment risk of such logistics projects. Several suggestions on how to prevent the risks of logistics projects in African countries are provided.
近年来,中国在非洲的直接投资大幅增长,使得物流企业直接投资的风险分析变得越来越重要。国际上有许多专门机构对国家投资风险进行评估。然而,他们的评估只分析了每个国家的政治和经济环境,而没有强调物流项目风险评估的重要性。本研究通过对中国对外直接投资最多的10个非洲主要国家的物流项目进行风险评估,填补了这一空白。在已有研究的基础上,主要采用人工神经网络建立中国对非洲物流项目的风险指标体系和非洲物流项目投资风险的宏观预警模型。对如何防范非洲国家物流项目风险提出了几点建议。
