The MDSC paradigm design for serverless computing defense 无服务器计算防御的MDSC范式设计
Zesheng Xi, Bo Zhang, Yuanyuan Ma, Chuan He, Yu-Na Wang
Serverless computing aims to handle all the system administration operations needed in cloud computing, thus, to provide a paradigm that greatly simplifies cloud programming. However, the security in serverless computing is regarded as an independent technology. The lack of security consideration in the initial design makes it difficult to handle the increasingly complicated attack scenario in serverless computing, especially for the vulnerabilities and backdoor based network attack. In this paper, we propose MDSC, a mimic defense enabled paradigm for serverless computing. Specifically, MDSC paradigm introduces Dynamic Heterogeneous Redundancy (DHR) structural model to serverless computing, and make fully use of features introduced by serverless computing to achieve an intrinsic security system with acceptable costs. We show the feasibility of MDSC paradigm by implementing a trial of MDSC paradigm based on Kubernetes and Knative. Analysis and experimental results show that MDSC paradigm can achieve high level security with acceptable cost.
无服务器计算旨在处理云计算中所需的所有系统管理操作,从而提供一种极大地简化云编程的范例。然而,无服务器计算中的安全性被视为一种独立的技术。由于在初始设计中缺乏安全考虑,使得无服务器计算中日益复杂的攻击场景难以应对,特别是针对漏洞和基于后门的网络攻击。在本文中,我们提出了MDSC,这是一种无服务器计算的模拟防御范例。MDSC范式将动态异构冗余(Dynamic Heterogeneous Redundancy, DHR)结构模型引入到无服务器计算中,充分利用无服务器计算引入的特性,实现成本可接受的内在安全系统。我们通过实现基于Kubernetes和Knative的MDSC范式的试验来展示MDSC范式的可行性。分析和实验结果表明,MDSC模式可以在可接受的成本下实现高水平的安全性。

Pei Zhang, Chengye Zhang, Weilong Gai
Path planning algorithm is the basis of unmanned ground platform to realize unmanned driving function. Traditional path planning algorithms mostly regard path planning as a geometric problem, which has great limitations on the work of unmanned platforms in the current complex environment. The reinforcement learning algorithm focuses on online planning and has the advantage of continuing to explore and find better solutions on the basis of effective actions. This paper studies path planning of unmanned ground platform based on reinforcement learning method. Aiming at the problems of low flexibility and slow convergence of the current reinforcement learning method in path planning, this paper improves the Q-learning algorithm based on the reinforcement learning algorithm and conducts simulation experiments and analyzes the experimental results. The analysis shows that the path planning algorithm of unmanned ground platform based on reinforcement learning has obvious advantages in performance.

The entity and event recognition method of power dispatching text information based on BERT-CRF 基于BERT-CRF的电力调度文本信息实体与事件识别方法
Wenteng Liang, Shang Dai, Yizhen You, Kang Yang, Jianan Zhang, Tai Sun, Ruyi Li, Yue Zhang, linxi zou
In order to improve the accuracy of power dispatching text analysis and the ability to guide the operation of the power grid, a power dispatch text entity recognition method is proposed based on Bidirectional Encoder Representations from Transformers-Conditional Random Field (BERT-CRF). Taking the power grid fault handling plan text as the research object, the entity marking method of the fault handling plan is proposed. The word vector of the plan entity is calculated based on the BERT pre-training model, the characterization ability of the professional entity of the plan is enhanced by fine-tuning the initial BERT parameters, and the recognition ability of the plan text sequence is improved from the overall situation to access the CRF layer in the neural network. Thus, an entity recognition model of fault handling plan is established based on the BERT-CRF. Through the verification of a power grid fault handling plan, the proposed method has higher power dispatch entity and event recognition accuracy compared with other algorithms.

Zheng Han, Zehao Jiang, Yuan Ju
Global pandemic due to the spread of COVID-19 has post challenges in a new dimension on facial recognition, where people start to wear masks. Under such condition, the authors consider utilizing machine learning in image inpainting to tackle the problem, by complete the possible face that is originally covered in mask. In particular, autoencoder has great potential on retaining important, general features of the image as well as the generative power of the Generative Adversarial Network (GAN). The authors implement a combination of the two models, context encoders and explain how it combines the power of the two models and train the model with 50,000 images of influencers faces and yields a solid result that still contains space for improvements. Furthermore, the authors discuss some shortcomings with the model, their possible improvements, as well as some area of study for future investigation for applicative perspective, as well as directions to further enhance and refine the model.

Evaluate the performance of the support vector machines ensemble 评估支持向量机集成的性能
Bowen Liu, Yihui Qiu
Diversity among the members of classifiers is deemed to be a key point in classifier ensemble. However, there doesn’t exist a widely accepted diversity measure and construct. In this paper, we propose a sample and feature double random construction of training sample variability. A support vector machine is used as the base classifier to construct the difference by distinguishing the regularization term C and the kernel function. Based on the negative correlation theory, the base classifier generalization error and disparity judgment functions are proposed, and the base classifier is integrated by ranking according to the judgment functions, which could achieve a higher accuracy rate by the support vector machine ensemble.

A comparative study of stock price prediction based on BP and LSTM neural network 基于BP和LSTM神经网络的股价预测比较研究
Shujia Huang, Ben Wang, Lingbo Hao, Zebin Si
In recent years, stock price prediction has become a research hotspot. The price of the stock market is unstable, which often rises or falls sharply due to the national policies, which makes it difficult for investors to achieve stable returns in the stock market. With the rapid rise of artificial intelligence, computers have become flexible in dealing with mathematical problems. Therefore, the extraordinary computing power of computers has been used to analyze and predict the trend of the stock market. More and more computer professionals began to enter the financial market and use neural network to study the trend of the stock market. This paper uses BP neural network and LSTM neural network to learn and predict the stock data of Shanghai Composite Index from January 2012 to June 2022. LSTM is a kind of RNN, but it is superior to other neural networks. It can effectively deal with data forgetting and gradient explosion problems and bring reliability to the prediction results of the model. The two models are evaluated by analyzing MAE, MSE and the time required for model training. The results show that LSTM model can not only learn longer time span than BP model, but also better than BP model in MAE and MSE indexes, which provides some reference and guidance for the prediction of medium and long-term stocks.
近年来,股票价格预测已成为一个研究热点。股票市场的价格不稳定,经常因为国家政策的影响而大幅上涨或下跌,这使得投资者很难在股票市场中获得稳定的回报。随着人工智能的迅速崛起,计算机在处理数学问题方面变得更加灵活。因此,计算机非凡的计算能力被用来分析和预测股票市场的趋势。越来越多的计算机专业人士开始进入金融市场,利用神经网络来研究股票市场的走势。本文采用BP神经网络和LSTM神经网络对上证综指2012年1月至2022年6月的股票数据进行学习和预测。LSTM是RNN的一种,但它优于其他神经网络。它能有效地处理数据遗忘和梯度爆炸问题,使模型的预测结果更加可靠。通过分析MAE、MSE和模型训练所需时间对两个模型进行评价。结果表明,LSTM模型不仅学习时间跨度比BP模型大,而且在MAE和MSE指标上也优于BP模型,为中长期股票预测提供了一定的参考和指导。

Flight disruption impact assessment based on expert system 基于专家系统的航班中断影响评估
Bingjie Liang, Fujun Wang, Jun Bi
When an abnormal flight occurs, if the previous flight cannot take off as planned, it will affect the subsequent flight, resulting in a downward impact. Therefore, airlines often adopt different recovery measures (including flight delays, flight cancellations, aircraft swaps, etc.) to eliminate or mitigate the downward impact. When evaluating the pros and cons of the recovery plan, the loss of delay, loss of flight cancellation and loss of aircraft exchange are generally considered. However, in fact, many complex factors are ignored when measuring these losses, such as food, transportation and accommodation costs of crew and passengers caused by flight delay, and compensation for delay, etc. Expert systems are suitable for situations where no or little data is available and the business logic is complex, and their introduction into flight disruption impact assessment is an exploration of artificial intelligence in civil aviation. The evaluation of the impact of flight disruptions by an expert system not only quantifies the benefits of recovery solutions, but also provides some reference for evaluating the advantages and disadvantages of existing models and algorithms.
当飞行发生异常时,如果前一个航班不能按计划起飞,会影响后续航班,造成向下冲击。因此,航空公司往往采取不同的恢复措施(包括航班延误、航班取消、飞机互换等)来消除或减轻下行影响。在评估恢复计划的利弊时,一般会考虑延误损失、航班取消损失和飞机交换损失。然而,实际上,在衡量这些损失时,忽略了许多复杂的因素,如航班延误造成的机组人员和旅客的饮食、交通和住宿费用,以及延误赔偿等。专家系统适用于无数据或数据少、业务逻辑复杂的情况,将专家系统引入航班中断影响评估是民航领域人工智能的探索。专家系统对航班中断影响的评估不仅量化了恢复方案的效益,而且为评估现有模型和算法的优缺点提供了一定的参考。

A training method for face representation models in realistic scenarios 一种现实场景下人脸表征模型的训练方法
C. Li
Face recognition has been widely used in daily life, but the existing model systems use processed high-quality datasets in training, while the face pictures in real scenes usually contain the influence of blurring, lighting, obscuring and other factors, thus making the existing face recognition models cannot perform well, and secondly, the existing face datasets have less data of Asian descent, resulting in the distribution learned by the models with the actual application. There is a certain error in the actual application. We propose a method to train face recognition models for realistic scenes by image augment of local face data to improve the classification accuracy of the models for low-quality images, and we demonstrate the feasibility of our method through experiments. Our method improves 0.619% and 0.414% in classifying images with added illumination and added random squares, respectively, compared to the current state-of-the-art methods.
人脸识别在日常生活中已经得到了广泛的应用,但是现有的模型系统在训练中使用的是经过处理的高质量数据集,而真实场景中的人脸图像通常会受到模糊、光照、遮挡等因素的影响,从而使得现有的人脸识别模型不能很好地发挥作用,其次,现有的人脸数据集中亚裔数据较少,导致模型在实际应用中学习到的分布不均匀。在实际应用中存在一定的误差。为了提高模型对低质量图像的分类精度,提出了一种通过局部人脸数据增强训练真实场景人脸识别模型的方法,并通过实验验证了该方法的可行性。与现有方法相比,我们的方法在增加光照和增加随机平方的情况下分别提高了0.619%和0.414%。

Low-cost, intelligence and short development cycle has become its trend of small satellites. A hybrid on-board avionics topology based on CAN bus and router was proposed. The telemetry was collected by On-Board Computer (OBC) via CAN bus, while the router integrated RS422, LVDS, Ethernet, Camera Link and TLK2711 interfaces, which support data rate varying from 1Mbps to 10Gbps and usually used by payloads, so it makes regular payloads integrated into the avionics much easier. The OBC used the PowerPC MPC8548 processor, which run at 1GHz. Plug and play mechanism was adopted to make the OBC recognize the devices dynamically when they powered on, which accelerated the system integration; furthermore, the software modules were also allowed to install or uninstall dynamically on-line for flexibility. For the modular and various interfaces supported, payload modules such as GNSS-R receiver, ADS-B receiver and camera electronics was easily integrated into the avionics box, so the signaling were transferred via the backplane instead of cables.
低成本、智能化、研制周期短已成为其发展的趋势。提出了一种基于CAN总线和路由器的混合机载航空电子拓扑结构。遥测数据由机载计算机(OBC)通过CAN总线收集,而路由器集成了RS422、LVDS、以太网、Camera Link和TLK2711接口,支持1Mbps到10Gbps的数据速率,通常用于有效载荷,因此使常规有效载荷集成到航空电子设备中变得更加容易。OBC使用PowerPC MPC8548处理器,运行频率为1GHz。采用即插即用机制,使OBC在设备上电时动态识别,加快了系统集成;此外,软件模块还允许在线动态安装或卸载,以提高灵活性。由于支持模块化和各种接口,GNSS-R接收机、ADS-B接收机和相机电子设备等有效载荷模块很容易集成到航空电子设备盒中,因此信号通过背板而不是电缆传输。
