In recent years, the in-depth development of the Internet has given birth to the learning mode of knowledge payment. Since 2016 to date, knowledge payment has gone through the process of fumbling to maturity from its infancy to emergence, and its market scale has expanded, and is expected to reach $50 billion after 2020, with college students expected to account for up to $10 billion in the interim. In this explosion of the knowledge payment industry, countless platforms have emerged and grown. However, among the existing platforms, most of them target at the whole society, and the products are many and miscellaneous, with insufficient quality control ability and low product repurchase rate. Today, with the rapid development of distributed ledger and big data mining technologies, this situation can be precisely solved.

With the diverse development of human-computer interaction. The gesture recognition-based interaction has a large-scale application prospect in collaborative robotics and smart home control. However, due to the similarity of gestures and occlusion, the previous methods have problems with the poor accuracy and shift of detection box. Aiming at the above issues, a gesture recognition method based on the Yolov4 deep learning algorithm is proposed. Firstly, gesture images were collected and annotated, and the data was processed by the GridMask and scale adjustment of data augmentation in order to improve the generalization performance of the network. Then K-means clustering algorithm was used to cluster the annotation boxes in the annotation dataset, by this way, the anchor box of YOLOV4 was optimized to improve the IOU accuracy. Finally, during the training process, focal loss and Consine warmup were adopted to improve the unbalanced sample number of classes and overfitting of the network. The experimental results shows that the proposed algorithm outperforms the main target detection models which include Yolov4, Yolov3 and Faster RCNN, the average recognition accuracy of this method reaches 99.4% and the FPS is 33fps. The proposed algorithm has good real-time performance.
随着人机交互的多样化发展。基于手势识别的交互在协同机器人和智能家居控制中具有广泛的应用前景。然而,由于手势和遮挡的相似性,以往的方法存在精度差和检测盒移位的问题。针对上述问题,提出了一种基于Yolov4深度学习算法的手势识别方法。首先,对手势图像进行采集和标注,并对数据进行GridMask和尺度调整的数据增强处理,以提高网络的泛化性能;然后使用K-means聚类算法对标注数据集中的标注框进行聚类,从而对YOLOV4的锚框进行优化,提高IOU精度。最后,在训练过程中,采用焦点损失和conine预热来改善网络的类样本数量不平衡和过拟合。实验结果表明,该算法优于yolo4、Yolov3和Faster RCNN等主要目标检测模型,平均识别准确率达到99.4%,帧率达到33fps。该算法具有良好的实时性。

Because of the low cost, strong mobility, and wide aerial view, the UAV is more and more widely used in the field of inspection and emergency rescue. Most of the traditional fire detection methods are based on the RGB color model, and their detection speed and accuracy are inadequate. In this paper, a fire detection method based on an autonomous drone platform is proposed. The drone flies on a designated route and carries an Ultra96-V2 development board with YOLOv3 fire detection algorithms deployed, which acts as an edge computing device to transmit the detection results back to the ground station in real time. Experimental results show that the recognition rate of the algorithm is 80%, the model memory compression is more than 75%, and the real-time detection frame rate is more than 3 FPS.

To solve the problems of low recognition accuracy and undetectable helmet of small targets in helmet detection in complex scenes, a helmet detection algorithm based on improved YOLOv5 and dynamic anchor box matching is proposed to improve the detection efficiency of small helmets in complex scenes. Firstly, by adding a small target detection layer in the YOLOv5 network, the detection accuracy of small targets is preliminarily improved; Secondly, convolution block attention model (CBAM) is added to the feature extraction network to enhance the information transmission between feature layers and the recognition of foreground and background by the neural network; Finally, to further improve the detection rate of small target helmet, the accuracy of a priori frame matching is enhanced by dynamic topK anchor frame matching. The weight of pre-training on the COCO data set is fused for detection and recognition to improve the generalization and accuracy of detection. The experimental results show that in the helmet data set constructed in this paper, the detection accuracy of helmets is 98.2%, and the helmet detection of small targets is realized.

This paper aims to build a model to predict used cars' reasonable prices based on multiple aspects, including vehicle mileage, year of manufacturing, fuel consumption, transmission, road tax, fuel type, and engine size. This model can benefit sellers, buyers, and car manufacturers in the used cars market. Upon completion, it can output a relatively accurate price prediction based on the information that users input. The model building process involves machine learning and data science. The dataset used was scraped from listings of used cars. Various regression methods, including linear regression, polynomial regression, support vector regression, decision tree regression, and random forest regression, were applied in the research to achieve the highest accuracy. Before the actual start of model-building, this project visualized the data to understand the dataset better. The dataset was divided and modified to fit the regression, thus ensure the performance of the regression. To evaluate the performance of each regression, R-square was calculated. Among all regressions in this project, random forest achieved the highest R-square of 0.90416. Compared to previous research, the resulting model includes more aspects of used cars while also having a higher prediction accuracy.

Therefore, we must find the causes and solutions fundamentally, and bring higher guarantee to the safety of laboratories. This paper mainly discusses the problems of laboratory safety management. It is of great significance to reduce the occurrence of safety accidents and improve the safety management level of computer laboratory.","PeriodicalId":164745,"journal":{"name":"2021 IEEE International Conference on Emergency Science and Information Technology (ICESIT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114659879","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 the background of “Internet+”, the use of advanced information technology and Internet of Things technology to create brand-new “smart venues” has become the main trend now. However, due to the large number of people, complex personnel types and frequent emergencies, it is a challenging task to manage the venue intelligently. This paper introduces a multidimensional feature fusion trajectory clustering algorithm, and designs a visual analysis system. The system can monitor the movement track of the venue personnel in real time, analyze the type of personnel, dig the movement rule of personnel, find abnormal situations in time, prevent and deal with emergencies, and well meet the demand of “smart venue”. By contrast with the existing trajectory clustering methods, the clustering algorithm logic more closely, clustering richer, more realistic value, provides strong technical support for emergency management of venues.
在“互联网+”的大背景下,利用先进的信息技术和物联网技术打造全新的“智慧场馆”已成为当前的主要趋势。然而,由于场馆人数众多,人员类型复杂,突发事件频发,对场馆进行智能化管理是一项具有挑战性的任务。介绍了一种多维特征融合轨迹聚类算法,并设计了可视化分析系统。该系统可以实时监控场馆人员的运动轨迹,分析人员类型,挖掘人员的运动规律,及时发现异常情况,预防和处理突发事件,很好地满足了“智慧场馆”的需求。与现有的轨迹聚类方法相比,该聚类算法逻辑更紧密,聚类内容更丰富,更具现实价值,为场馆应急管理提供了强有力的技术支持。
