The purpose of this study was to investigate the clinical value of CT angiography (CTA) images processed by the segmentation denoising technique based on deep convolution neural network algorithm in the diagnosis of abdominal aortic aneurysm (AAA) and the detection of disease changes. A total of 98 patients with ruptured AAA were retrospectively selected as the study subjects. Patients were grouped according to whether the CTA images were optimized, the images receiving artificial intelligence segmentation and denoising were set as the observation group, and the CTA images without optimization were set as the control group. The detection and diagnosis effects of CTA images before and after the treatment were compared. The surgical results were used as the standard to analyze the diagnostic effect, and the maximum diameter measurement results of AAA and the proportion results of intraluminal thrombus (ILT) were compared. Although the sensitivity and accuracy of diagnosis in the observation group (97.73% and 94.9%) were higher than those in the control group (95.45% and 92.86%), there was no significant statistical significance ( P > 0.05 ). When the diameter of AAA was no less than 5 cm, all results showed that the coverage percentage of intraluminal thrombus (ILT) was over 50%. When the diameter of AAA was less than 5 cm, only 55.56% of the results showed that the percentage of ILT coverage was over 50%, with considerable differences ( P > 0.05 ). According to the results of the study, it was found that there was a certain relationship between the thrombus coverage of the abdominal aortic wall and the growth rate of AAA. The deep convolution neural network algorithm had a certain effect on the treatment of CTA, but it is not obvious. However, CTA had a better clinical diagnostic effect on AAA.
本研究旨在探讨基于深度卷积神经网络算法的分割去噪技术处理的CT血管造影(CTA)图像在腹主动脉瘤(AAA)诊断和疾病变化检测中的临床价值。回顾性选择98例AAA破裂患者作为研究对象。根据CTA图像是否优化进行分组,将经过人工智能分割去噪的图像设为观察组,未优化的CTA图像设为对照组。比较治疗前后CTA图像的检测和诊断效果。以手术结果为标准分析诊断效果,并比较AAA最大直径测量结果与腔内血栓(ILT)比例测量结果。观察组诊断的敏感性和准确性(97.73%和94.9%)均高于对照组(95.45%和92.86%),但差异无统计学意义(P > 0.05)。当AAA直径不小于5cm时,所有结果均显示腔内血栓(ILT)覆盖率大于50%。当AAA直径小于5 cm时,只有55.56%的结果显示ILT覆盖率超过50%,差异有统计学意义(P > 0.05)。根据研究结果,发现腹主动脉壁血栓覆盖与AAA生长速率存在一定关系,深度卷积神经网络算法对CTA治疗有一定效果,但不明显。而CTA对AAA的临床诊断效果较好。

In recent times, the utility and privacy are trade-off factors with the performance of one factor tends to sacrifice the other. Therefore, the dataset cannot be published without privacy. It is henceforth crucial to maintain an equilibrium between the utility and privacy of data. In this paper, a novel technique on trade-off between the utility and privacy is developed, where the former is developed with a metaheuristic algorithm and the latter is developed using a cryptographic model. The utility is carried out with the process of clustering, and the privacy model encrypts and decrypts the model. At first, the input datasets are clustered, and after clustering, the privacy of data is maintained. The simulation is conducted on the manufacturing datasets over various existing models. The results show that the proposed model shows improved clustering accuracy and data privacy than the existing models. The evaluation with the proposed model shows a trade-off privacy preservation and utility clustering in smart manufacturing datasets.
近年来,效用和隐私是一种权衡因素,其中一个因素的表现往往会牺牲另一个因素。因此,没有隐私就不能发布数据集。因此,保持数据的实用性和隐私性之间的平衡至关重要。本文提出了一种实用与隐私权衡的新技术,其中前者采用元启发式算法,后者采用密码学模型。该实用程序通过聚类过程实现,隐私模型对模型进行加密和解密。首先对输入数据集进行聚类,聚类后保持数据的隐私性。在各种现有模型的制造数据集上进行了仿真。结果表明,与现有模型相比,该模型具有更高的聚类精度和数据隐私性。该模型在智能制造数据集中体现了隐私保护和效用聚类的权衡。

In the educational sector, an evaluation index is required to draw up planning. The establishment of an evaluation index is useful to properly predict the employment quality of graduates. Such valuable indices help educational administrative departments to formulate talent training standards. Multicriteria decision making is a decision-making tool that can be used in the formulation of the evaluation index. This research work proposes an effective evaluation model to assess the employment quality of graduate students. The model uses 10 evaluation indicators which are considered to be the standard employment quality. The proposed evaluation method utilizes the entropy method and fuzzy comprehensive evaluation. Correlation between the employment quality evaluation index and employment quality is computed. The analytic hierarchy model is used to solve the weight of each employment quality evaluation index to the employment quality evaluation coefficient. According to the value characteristics of the 14 employment indicators, the expert method is used to assign scores to the sample data on each indicator. Thus, the indicator scores of the sample corresponding to the item are obtained. Through the evaluation of the employment quality of a certain university, the evaluation results are consistent with the actual employment quality of graduates. The employment quality evaluation model of college graduates established in this paper provides effective means and applications.

The traditional image object detection algorithm applied in power inspection cannot effectively position power components, and the accuracy of recognition is low in scenes with some interference. In this research, we proposed a data-driven power detection method based on the improved YOLOv4-tiny model, which combined the ResNet-D module and the adjusted Res-CBAM to the backbone network of the existing YOLOv4-tiny module. We replaced the CSPOSANet module in the YOLOv4-tiny backbone network with the ResNet-D module to reduce the FLOPS required by the model. At the same time, the adjusted Res-CBAM whose feature fusion ways were replaced with stacking in the channels was combined as an auxiliary classifier. Finally, the features of five different receptive scales were used for prediction, and the display of the results was optimized by merging the prediction boxes. In the experiment, 57134 images collected on the power inspection line were processed and labeled, and the default anchor boxes were re-clustered, and the speed and accuracy of the model were evaluated by video and validation set of 3459 images. Processing multiple pictures and videos collected from the power inspection projects, we re-clustered the default anchor box and tested the speed and accuracy of the model. The results show that compared with the original YOLOv4-tiny model, the accuracy of our method that can position objects under occlusion and complex lighting conditions is guaranteed while the detection speed is about 13% faster.
传统的图像目标检测算法在电力巡检中不能有效定位电力部件,在存在一定干扰的场景中识别精度较低。在本研究中,我们提出了一种基于改进的YOLOv4-tiny模型的数据驱动功率检测方法,将ResNet-D模块和调整后的Res-CBAM结合到现有YOLOv4-tiny模块的骨干网中。我们将YOLOv4-tiny骨干网中的cspoanet模块替换为ResNet-D模块,以降低模型所需的FLOPS。同时,结合调整后的Res-CBAM作为辅助分类器,将其特征融合方式替换为通道中的叠加。最后,利用5种不同接受尺度的特征进行预测,并通过合并预测框优化结果的显示。在实验中,对电力巡检线上采集的57134幅图像进行处理和标记,对默认锚盒进行重新聚类,并通过3459幅图像的视频和验证集对模型的速度和准确性进行评估。处理从电力巡检项目中收集的多张图片和视频,对默认锚盒进行重新聚类,并测试模型的速度和准确性。结果表明,与原始的YOLOv4-tiny模型相比,我们的方法在遮挡和复杂光照条件下的目标定位精度得到了保证,检测速度提高了13%左右。

In recent years, due to the rapid development of rural tourism, rural tourism has lost its unique rurality, which has led to a certain impact on the sustainable development of rural tourism. Primarily, based on the rural characteristics, the social environment development, population development, and economic development are taken as the research indexes, and the evaluation index system of rural tourism destination is constructed. Afterward, an empirical study on the spatial pattern of rural tourism is carried out with examples, and the model is simulated and analyzed by MATLAB software. Finally, the spatial autocorrelation method is used to analyze the evolution characteristics of the rural tourism spatial pattern. The results show that through the analysis of the evaluation error curve of the Back Propagation Neural Network (BPNN), the evaluation error and the actual error range are within 0.08%, which proves that the BPNN algorithm has good calculation accuracy. The BPNN rural tourism destination rurality evaluation model established here can make an effective evaluation of rural tourism space. The results show that the proportion of employees in the primary industry and the penetration rate of mobile phones are the decisive factors in the adjustment of industrial structure and social environmental factors, respectively. Rural per capita tourism income and the proportion of primary industry output value will also have a certain impact on rural evolution. Certain guiding significance is provided for the sustainable development of rural tourism.
近年来,由于乡村旅游的快速发展,乡村旅游失去了其独特的乡村性,这对乡村旅游的可持续发展造成了一定的影响。首先,根据乡村特点,以社会环境发展、人口发展和经济发展为研究指标,构建乡村旅游目的地评价指标体系。随后,结合实例对乡村旅游空间格局进行实证研究,并利用MATLAB软件对模型进行仿真分析。最后,运用空间自相关方法分析了乡村旅游空间格局的演化特征。结果表明:通过对bp神经网络(Back Propagation Neural Network, BPNN)评估误差曲线的分析,评估误差与实际误差范围在0.08%以内,证明了bp神经网络算法具有良好的计算精度。本文建立的BPNN乡村旅游目的地乡村性评价模型可以对乡村旅游空间进行有效的评价。研究结果表明,第一产业从业人员占比和手机普及率分别是产业结构调整的决定性因素,社会环境因素的决定性因素是手机普及率。农村人均旅游收入和第一产业产值占比也会对乡村演化产生一定的影响。对乡村旅游的可持续发展具有一定的指导意义。

To retain valuable information to the maximum extent and enhance the ability to mine the crude oil trade purchase price demand, this paper proposes a crude oil trade purchase model based on the DEA-Malmquist algorithm. The intranet of the management and control platform shall share the same database, and the intranet shall only allow managers to access and manage the system and only allow all registered users to access and realize data exchange between the intranet and the intranet through two-dimensional code scanning; moreover, due to the resource sharing between the intranet and the intranet for crude oil trade procurement, suppliers and other registered users can immediately grasp the procurement trends of enterprises. Under the DEA-Malmquist algorithm, the uncertainty of procurement management is analyzed by fuzzy theory, and the refined procurement decision model with fuzzy parameters is established. The optimal order time and purchase quantity are determined through the symbol distance and the method of the center of gravity. Experimental results show that the method can effectively retain valuable information in the initial sequence and has better practical application value of material procurement demand intelligent mining. The proposed model obtained the highest accuracy of 98.62%.
为了最大限度地保留有价值的信息,增强对原油交易购买价格需求的挖掘能力,本文提出了一种基于DEA-Malmquist算法的原油交易购买模型。管控平台的内部网应共享同一数据库,内部网只允许管理人员访问和管理系统,只允许所有注册用户访问,并通过二维码扫描实现内部网与内部网之间的数据交换;此外,由于内部网与原油贸易采购内部网之间的资源共享,供应商和其他注册用户可以立即掌握企业的采购动态。在DEA-Malmquist算法下,运用模糊理论分析了采购管理的不确定性,建立了带有模糊参数的精细化采购决策模型。通过符号距离和重心法确定最优订货时间和采购数量。实验结果表明,该方法能有效保留初始序列中有价值的信息,对物资采购需求智能挖掘具有较好的实际应用价值。该模型获得了98.62%的最高准确率。

The Influence of Artificial Intelligence on Art Design in the Digital Age 数字时代人工智能对艺术设计的影响
Pub Date : 2021-12-27 DOI: 10.1155/2021/4838957
Yan Shen, Fangzheng Yu
With the advancement of technology represented by artificial intelligence, art creation is becoming increasingly rich, and content expression is intelligent, interactive, and data-driven, making the relationship between technology, art, and people increasingly close and bringing opportunities for the development of emerging interaction. Artificial intelligence technologies aim to perfectly replicate the human mind by enabling natural responses based on the surrounding environment, decoding emotions, and recognizing human traits within the energy range. Driven by AI technology, interactive art no longer focuses on a single audiovisual sensory experience but rather on integrated artistic expressions that are highly interactive, kinetic, and emotional, based on the study of natural human behavior and integrated senses, combined with intelligence. In this paper, we first sort out the intersection of AI technology development and interactive art expression streams on the timeline based on historical development and analyze the deconstructive relationship between the two from the macroperspective of the historical development of technology and art. First, based on the conceptual connotation, development history, technical application, and singularity outlook of AI, we identify the current characteristics and development trends of interactive art; second, based on exploring the advantages of AI technology, we propose the impact of AI on the creative thinking, creative mode, and artistic experience of interactive art and establish the paradigm of interactive art creation in the context of AI. It solves the problem that experts are unable to quickly locate the category of painters when facing different styles of unsigned digital Chinese painting images in the authenticity identification task.
随着以人工智能为代表的技术进步,艺术创作日益丰富,内容表达智能化、互动性、数据化,使得技术、艺术、人三者之间的关系日益紧密,为新兴互动的发展带来机遇。人工智能技术的目标是根据周围环境做出自然反应,解码情绪,识别能量范围内的人类特征,从而完美地复制人类的思维。在人工智能技术的推动下,互动艺术不再专注于单一的视听感官体验,而是基于对人类自然行为和综合感官的研究,结合智能,进行交互性、动态性、情绪性强的综合艺术表现。本文首先在历史发展的时间轴上梳理人工智能技术发展与互动艺术表现流的交集,并从技术与艺术的历史发展的宏观角度分析两者之间的解构关系。首先,基于人工智能的概念内涵、发展历史、技术应用、奇点展望,明确当前互动艺术的特点和发展趋势;其次,在探索AI技术优势的基础上,提出AI对互动艺术创作思维、创作模式、艺术体验的影响,建立AI背景下的互动艺术创作范式。解决了专家在真伪鉴定任务中面对不同风格的无签名数字中国画图像时无法快速定位画家类别的问题。

The study aims to improve the economic income of pig breeding industry under environmental regulation and control the environmental pollution caused by pig breeding. Long short-term memory (LSTM) neural network combined with environmental regulation is proposed to forecast the price of live pigs, to reduce the cost of environmental pollution control and improve the production efficiency of pig breeding. Primarily, analyses are made on the industrial structure and pollution of pigs in China, and studies are carried out on the inevitability of large-scale and intensive pig breeding. Then, pig breeding and environmental pollution are coordinated under the environmental regulation. From the perspective of green total factor productivity, calculation is made on the profit of pig breeding and the cost of environmental pollution control. Next, the LSTM neural network is used to predict the price of live pigs, thus effectively controlling the scale of pig breeding and making timely decisions that conform to market rules. The results show that with the increase of feed and land prices, the advantages of large-scale pig breeding gradually become prominent, which leads to the small- and medium-sized scale farmers withdrawing from the market. Compared with other similar models, the designed model can better simulate the future trend of hog price, of which the prediction accuracy is over 80%. When combined with environmental regulations, the prediction accuracy of the model for different data sets reaches 83%, so the designed model can better predict the changing trend of the price of live pigs, thus improving the production efficiency of large-scale pig farmers.
本研究旨在提高生猪养殖业在环境调控下的经济收入,控制生猪养殖对环境的污染。提出了长短期记忆(LSTM)神经网络与环境调控相结合的生猪价格预测方法,以降低环境污染治理成本,提高生猪养殖生产效率。首先对中国生猪产业结构和污染进行了分析,研究了生猪规模化集约化养殖的必然性。然后,在环境监管下协调生猪养殖和环境污染。从绿色全要素生产率的角度,计算生猪养殖利润和环境污染治理成本。其次,利用LSTM神经网络对生猪价格进行预测,有效控制生猪养殖规模,及时做出符合市场规律的决策。结果表明,随着饲料和土地价格的上涨,生猪规模化养殖的优势逐渐凸显,导致中小养殖户退出市场。与其他同类模型相比,所设计的模型能较好地模拟生猪价格未来走势,预测准确率达80%以上。结合环境法规,模型对不同数据集的预测准确率达到83%,因此所设计的模型可以更好地预测生猪价格的变化趋势,从而提高规模化养猪户的生产效率。
