Yingshi Chen
As technology is much more developed, it has already merged with the daily life of people. Because of the characteristic of the network— no limitation, part of people believe that they are closer to their family and friends, while it makes people feel lonelier since companions are virtual. Therefore, it is easier to cause negative emotions and then lead to a more serious downside such as depression if those emotions cannot be alleviated or even eliminated on time. In this paper, the author focuses on the analysis of how to minimize the negative emotions so that to avoid more serious problems. All data are collected from COVID-19 Real World Worry Dataset which is related to Twitter. The author utilizes the comparison of P-value for each variable and Stepwise. Selection method to identify the most effective factor for causing negative emotions (anxiety, worry, fear, anger, disgust, and sadness). The author found that the frequency of participants on Twitter is the most influential variable. In other words, it is important to study ways to relieve negative emotions from Twitter emotions cannot be alleviated or even eliminated on time.
随着科技的发展,它已经融入了人们的日常生活。由于网络不受限制的特点,一部分人认为他们与家人和朋友更亲近,但由于同伴是虚拟的,这让人们感到更孤独。因此,如果这些情绪不能及时缓解甚至消除,就更容易引起消极情绪,进而导致抑郁等更严重的负面影响。在本文中,作者着重分析了如何将负面情绪最小化,从而避免更严重的问题。所有数据收集自与Twitter相关的COVID-19真实世界担忧数据集。作者采用了各变量p值的比较和Stepwise。识别导致负面情绪(焦虑、担心、恐惧、愤怒、厌恶和悲伤)的最有效因素的选择方法。作者发现,参与者使用Twitter的频率是最具影响力的变量。换句话说,研究如何缓解Twitter上无法及时缓解甚至消除的负面情绪是很重要的。

Momentum Method for Improving the Convergence of Newton-Raphson Method for Nonlinear Circuit Transient Simulations 改进非线性电路暂态仿真牛顿-拉夫逊法收敛性的动量法
Wen Hu
With the growing scale of circuits designed nowadays, the computational efficiency of transient circuit simulations that verify the behavior of circuits becomes an important topic. The popular Newton-Raphson method applied in simulation programs like SPICE exhibit convergence issues when processing circuits with a mix of linear and nonlinear devices. Traditional methods proposed to tackle these issues are either effective to a limited group of circuits or entail more computation. This paper proposes the momentum method to improve convergence without requiring additional computation, demonstrates its effectiveness, and provides experimental results on an example.
随着当今电路设计规模的不断扩大,验证电路行为的瞬态电路仿真的计算效率成为一个重要的课题。在SPICE等仿真程序中应用的流行牛顿-拉夫森方法在处理混合线性和非线性器件的电路时会出现收敛问题。解决这些问题的传统方法要么对有限的电路组有效,要么需要更多的计算。本文提出了一种无需额外计算就能提高收敛性的动量方法,并对其有效性进行了验证,给出了一个算例的实验结果。

ParallelMOT: Pay More Attention in Tracking ParallelMOT:更注重跟踪
Changzhi Lv, Changdong Shu, Yingjun Lv, Chunsheng Song
Modern multiple object tracking has made great progress of the JDE model. Because the JDE model uses a shared model, its calculation speed and accuracy have been greatly improved. But using the same network to predict detection and re- ID will affect each other when the network feedback, thereby reducing the MOTA (Evaluation Measures for MOTChallenge) accuracy, and when the network detects the object and ID information separately, it will greatly increase the computing time. We propose a new MOT method named ParallelMOT, which uses two different branches to reduce the mutual influence of network feedback, and uses object information fusion to improve the feature extraction of the object, and uses a new network model to predict embedding for achieving better MOT accuracy.
现代多目标跟踪在JDE模型上取得了很大的进步。由于JDE模型使用了共享模型,其计算速度和精度都得到了很大的提高。但使用同一网络进行预测检测和重识别时,网络反馈会相互影响,从而降低MOTA (Evaluation Measures for MOTChallenge)的精度,并且当网络分别检测对象和ID信息时,会大大增加计算时间。我们提出了一种新的MOT方法——并行MOT,该方法使用两个不同的分支来减少网络反馈的相互影响,使用目标信息融合来改进目标的特征提取,并使用新的网络模型来预测嵌入以获得更好的MOT精度。

Chenge Hu, Huaqing Zhang, Yuyu Zhou, Ruixin Guan
Hilbert-Schmidt independence criterion (HSIC) which is a kernel-based method for testing statistical dependence between two random variables. It is widely applied in a variety of areas. However, this approach comes with a question of the selection of kernel functions. In this paper, we conduct an experiment using the forest fire data from UCI in the context of independence test, contrasting four commonly used kernel functions: Linear kernels, Gaussian kernels, Brownian kernels, Matern kernels. Through comparing p-value and rejection rate of hypothesis test we constructed; it is shown that the different choices in associated kernel function of HSIC give comparable performance on results.
希尔伯特-施密特独立准则(Hilbert-Schmidt independence criterion, HSIC)是一种基于核函数的检验两个随机变量之间统计相关性的方法。它被广泛应用于各种领域。然而,这种方法带来了核函数选择的问题。本文利用UCI的森林火灾数据,在独立性检验的背景下进行了实验,对比了四种常用的核函数:线性核函数、高斯核函数、布朗核函数和Matern核函数。通过比较假设检验的p值和拒绝率,我们构造了;结果表明,HSIC相关核函数的不同选择对结果的影响是相当的。

Improve Semantic Segmentation of Remote sensing Images with K-Mean Pixel Clustering: A semantic segmentation post-processing method based on k-means clustering 利用k-均值像素聚类改进遥感图像语义分割:一种基于k-均值聚类的语义分割后处理方法
Xiaohui Zeng, Isabelle Chen, Pai Liu
Semantic image segmentation has been used to detect objects and label pixels in images. It has been applied to high-resolution remote sensing images to detect different types of terrains and landforms. However, the accuracy of the existing methods is not always satisfactory. Here we propose a semantic segmentation post-processing method using K-mean clustering. Our method aggregates the predictions from network training algorithms such as Unet and HrNet [1], and then performs postprocessing using K-Mean clustering iteratively [2] [3]. The accuracy of our method improves as the number of iterations increases. Source code is at https://github.com/carlsummer/SSK.

In this paper, we propose a method to predict the sales of electric vehicles by analyzing people's comments on social media. We scrap user comments from a Chinese social media “Weibo” and try to predict the electric vehicle sales in China by using Natural Language Processing (NLP). Sentiment score, number of comments and likes, and keyword existence are treated as input indicators. We test linear regression, random forest, and gradient boosting algorithm during the experiment. The result shows that the model which using gradient boosting algorithm to predict the market share of electric vehicles has the best performance.

Adaptive firefly algorithm based on reverse search strategy 基于反向搜索策略的自适应萤火虫算法
H. Yin, Huipeng Meng, YuChen Zhang
Firefly algorithm is proposed by Prof. Yang Xinshe for solving global optimization problems, which uses the principle of mutual attraction of fireflies in nature. The firefly algorithm is a branch of evolutionary algorithms, which is often used to solve single-objective global optimization problems with fewer parameters, easy to implement and easy to understand. However, the traditional firefly algorithm uses the full-attraction model in updating, which is easy to fall into local optimum. Therefore, a firefly algorithm that performs backward search with Poisson distributed probabilities is proposed, which enables the firefly to search more widely in the solution space and easily jump out of the local optimum. Comparative experiments are conducted on 28 functions of the CEC2013 test set. The experimental results show that in 22 of the functions the firefly with the reverse search strategy performs more accurately than the other improved firefly algorithms and in 26 of the functions the firefly with the reverse search strategy converges faster than the other fireflies.
萤火虫算法是杨新社教授利用自然界萤火虫相互吸引的原理,提出的求解全局优化问题的算法。萤火虫算法是进化算法的一个分支,常用于解决参数少、易于实现、易于理解的单目标全局优化问题。而传统的萤火虫算法在更新时采用全吸引模型,容易陷入局部最优。因此,提出了一种利用泊松分布概率进行反向搜索的萤火虫算法,使萤火虫在解空间中搜索范围更广,容易跳出局部最优。对CEC2013测试集的28个函数进行了对比实验。实验结果表明,在22个功能中,反向搜索策略的萤火虫比其他改进的萤火虫算法执行得更准确;在26个功能中,反向搜索策略的萤火虫比其他改进的萤火虫收敛得更快。

Jinyang Jia, Gongxuan Liu
Data center networks are a critical part in building a powerful data center, while tasks may start at any container and VMs may move around in physical machines as well. Not mentioning network traffic should be balanced while using network resources such as switches as efficient as possible. This paper summarizes two papers that talks about the data center networks. The first section summarizes a paper that describes efficient protocols in data centers, PortLand[1], where VMs could move to new physical machines without breaking TCP connection and achieve fast plug-and-play for new machine. The second section summarizes a survey paper which studies one of Facebook's data centers that provides web services. It mainly focuses on network traffic stability on server hosts and the traffic patterns on switches with different responsibilities.
