Ziyang Pan, Zhishan Huang, Xiaowen Lin, Songxia Li, Huanze Zeng, Daifeng Li
The intelligent analysis and marketing prediction of high-tech enterprises based on artificial intelligence is a hot topic in the field. Most of the existing researches mainly focus on taking the internal structural features of the enterprise as the starting point to study the influencing factors of enterprise marketing trends. Different with previous studies, This research attempts to simulate the analyzing and decision processes of domain experts towards issues of enterprise operations by using artificial intelligent. One main challenge of the research is to simulate domain experts’ behaviors of analyzing multi-data including both structured and unstructured data, especially how to extract knowledge, patterns and import factors from unstructured data to support enterprise decisions. In order to solve the challenge mentioned above, an intelligent analysis framework MS-LSTM based on business management theory is proposed. Firstly, MS-LSTM collects, processes and analyzes multi-data by using an encoder strategy module, which contains more than 10 strategy models such as normalization, one-hot, distribution fitting, time series completion, semantic encoding, Bert, etc., providing high quality input for downstream tasks. Finally, a LSTM based time series processing model is proposed to make marketing prediction based on upstream processed multi-source data. Extensive experiments are conducted to verify the proposed model. Compared with traditional benchmark model, the proposed MS-LSTM could efficiently extract meaningful knowledge and patterns, which could be explained to a certain extent by business management theory, from multi-source data. The model has improved the accuracy of enterprise trend prediction by 19.3 times compared with state-of-art baselines, which further verify the application values of the research.
基于人工智能的高新技术企业智能分析与营销预测是该领域的研究热点。现有的研究大多集中在以企业内部结构特征为出发点,研究企业营销趋势的影响因素。与以往的研究不同,本研究试图利用人工智能模拟领域专家对企业运营问题的分析和决策过程。研究的一个主要挑战是如何模拟领域专家分析包括结构化和非结构化数据在内的多数据的行为,特别是如何从非结构化数据中提取知识、模式和导入因素以支持企业决策。为了解决上述问题,提出了基于企业管理理论的智能分析框架MS-LSTM。首先,MS-LSTM通过编码器策略模块对多数据进行采集、处理和分析,该模块包含归一化、一热、分布拟合、时间序列补全、语义编码、Bert等10多个策略模型,为下游任务提供高质量的输入。最后,提出了一种基于LSTM的时间序列处理模型,基于上游处理的多源数据进行营销预测。进行了大量的实验来验证所提出的模型。与传统的基准模型相比,本文提出的MS-LSTM可以从多源数据中高效地提取有意义的知识和模式,这些知识和模式在一定程度上可以用企业管理理论来解释。该模型对企业趋势预测的准确率较现有基线提高了19.3倍,进一步验证了研究的应用价值。

Early Diagnosis of Alzheimer's Disease Using Hybrid Word Embedding and Linguistic Characteristics 基于混合词嵌入和语言特征的阿尔茨海默病早期诊断
Yangyang Li
Early detection of Alzheimer's Disease (AD) is of great importance to the benefits of AD patients, including lessening symptoms and alleviating the financial burden of health care. As one of the leading signs of AD, changes of language capability can potentially be used for early diagnosis of AD. In this paper, I develop an automatic and accurate diagnostic model by using the linguistic characteristics of the subjects and hybrid word embedding. I detected linguistic features such as pauses, unintelligible words, repetitions, etc. from transcripts of interviews. Then I create a text embedding by combining word vectors from Doc2vec and ELMo. Moreover, by tuning hyperparameters of the machine learning pipeline (e.g., model regularization parameter, learning rate and vector size of Doc2vec, and vector size of ELMo), I achieve 91% classification accuracy and an Area Under the Curve (AUC) of 97% for distinguishing early AD from healthy subjects. Compared with the method which only uses word count, I improved the absolute detection accuracy by 10%, and the absolute AUC by 9%. Moreover, I study the stability of the model by repeating experiment and find out that the model is stable even though my training data is split randomly. My algorithms have high detection accuracy and are stable. This model could be used as a large-scale screening method for AD, as well as a complement to doctors’ detection of AD.
早期发现阿尔茨海默病(AD)对阿尔茨海默病患者的利益非常重要,包括减轻症状和减轻医疗保健的经济负担。作为阿尔茨海默病的主要症状之一,语言能力的变化有可能用于阿尔茨海默病的早期诊断。本文利用主题的语言特征和混合词嵌入,建立了一个自动准确的诊断模型。我从采访记录中发现了语言特征,如停顿、难以理解的单词、重复等。然后我通过结合Doc2vec和ELMo的词向量来创建文本嵌入。此外,通过调整机器学习管道的超参数(例如,模型正则化参数,Doc2vec的学习率和向量大小,ELMo的向量大小),我实现了91%的分类准确率和97%的曲线下面积(AUC),用于区分早期AD和健康受试者。与仅使用单词计数的方法相比,我的绝对检测准确率提高了10%,绝对AUC提高了9%。此外,我通过重复实验来研究模型的稳定性,发现即使我的训练数据是随机分割的,模型也是稳定的。该算法具有较高的检测精度和稳定性。该模型可作为AD的大规模筛选方法,也可作为医生对AD检测的补充。

A Graph Convolution model considering label co-occurrence LC_GCN 考虑标签共现的图卷积模型LC_GCN
Chaoshun Chang, Xiaoyong Li, Yali Gao
Graph convolution network (GCN) is a Semi-supervised algorithm that applies the idea of convolution to graph structure data, and it is used for node classification tasks in graphs. Original algorithm only considers the characteristics and adjacency of the nodes in the graph, but fails to consider the association between label and simply represents the label as a one-hot vector. In this paper, we propose LC_GCN. This model contains a label convolution module based on the original GCN, and use it to get a better classifier. An open pre-trained word vector is used as the label feature, and we designed an algorithm to use the conditional probability of the association between label to generate adjacency matrix of labels to obtain the classifier by GCN. Then combine it with the original node GCN, and put the vector obtained by the node through the GCN into this classifier. Experimental results show that our proposed LC_GCN outperforms the existing algorithms.
图卷积网络(GCN)是一种将卷积思想应用于图结构数据的半监督算法,用于图中的节点分类任务。原始算法只考虑图中节点的特征和邻接性,没有考虑标签之间的关联,简单地将标签表示为一个单热向量。本文提出LC_GCN。该模型包含一个基于原始GCN的标签卷积模块,并使用它来获得更好的分类器。使用开放的预训练词向量作为标签特征,设计了一种算法,利用标签之间关联的条件概率生成标签邻接矩阵,通过GCN获得分类器。然后将其与原始节点GCN结合,将该节点通过GCN得到的向量放入该分类器中。实验结果表明,我们提出的LC_GCN算法优于现有算法。

Ensemble Neural Networks with Random Weights for Classification Problems 基于随机权值的集成神经网络分类问题
Ye Liu, Weipeng Cao, Zhong Ming, Qiang Wang, Jiyong Zhang, Zhiwu Xu
To improve the prediction accuracy and stability of neural networks with random weights (NNRWs), we propose a novel ensemble NNRWs (E-NNRW) in this paper, which initializes its base learners by different distributions to improve their diversity. The final prediction results of the E-NNRW model are determined by these base learners through a voting mechanism, which minimizes the specific "blind zone" of a single learner, thus achieving higher prediction accuracy and better stability. Taking the random vector functional link network (RVFL), one of the most representative algorithms in NNRWs, as an example, we fully evaluate the performance of the proposed algorithm on nine benchmark classification problems. Extensive experimental results fully demonstrate the effectiveness of our method.
为了提高随机权重神经网络(nnrw)的预测精度和稳定性,本文提出了一种新的集成nnrw (E-NNRW),该方法通过不同的分布初始化其基础学习器,以提高其多样性。E-NNRW模型的最终预测结果由这些基础学习器通过投票机制决定,最大限度地减少了单个学习器的特定“盲区”,从而达到更高的预测精度和更好的稳定性。以NNRWs中最具代表性的随机向量函数链接网络(RVFL)算法为例,对该算法在9个基准分类问题上的性能进行了全面评价。大量的实验结果充分证明了该方法的有效性。

Generating Adversarial Examples Based on Subarea Noise Texture for Efficient Black-Box Attacks 基于子区域噪声纹理生成对抗样本的高效黑盒攻击
Zhijian Chen, Jing Liu, Hui Chen
Nowadays, machine learning algorithms play a vital role in the field of artificial intelligence. However, it has been proved that deep convolutional networks (DCNs) are vulnerable to interference from adversarial examples. In this paper, we innovatively simulate natural textures by adding continuous noise to image subareas to generate adversarial examples, which can achieve up to 90% fooling rate on the object detection tasks (YOLOv3/Inceptionv3). The experimental results show that DCNs based on ImageNet dataset training relies too much on the feature aggregation of lower subareas in the classification task. It is instructive that when training DCNs, we need to consider not only the pursuit of accuracy but also the nature of model feature learning.
如今,机器学习算法在人工智能领域发挥着至关重要的作用。然而,已经证明深度卷积网络(DCNs)容易受到对抗性示例的干扰。在本文中,我们创新地通过在图像子区域中添加连续噪声来模拟自然纹理来生成对抗样例,在目标检测任务(YOLOv3/Inceptionv3)上可以达到高达90%的愚弄率。实验结果表明,在分类任务中,基于ImageNet数据集训练的DCNs过于依赖下层子区域的特征聚合。在训练DCNs时,不仅要考虑对准确性的追求,还要考虑模型特征学习的本质,这是很有指导意义的。

Zhixiang Luo, Jie Zhu, Zhensong Li, Saihu Liu
Tibetan word segmentation and part-of-speech tagging are the most basic parts of Tibetan natural language processing, and its accuracy and performance have a crucial impact on many subsequent tasks. Considering the insufficiency of the pipeline model of word segmentation and part-of-speech tagging, this paper uses an integrated model of BiGRU-CRF word segmentation and part-of-speech tagging based on deep learning to simultaneously process two tasks of Tibetan word segmentation and part-of-speech tagging in one step. After conducting experiments on the Tibetan corpus collected in "Humanistic Tibet", the joint F1 value of Tibetan word segmentation and part-of-speech tagging was 92.48%.

TDOA Parameter Estimation based on VMD-WTD in Satellite Interference Location 卫星干扰定位中基于VMD-WTD的TDOA参数估计
Shibing Zhu, Haifeng Shuai, Changqing Li, Rui Liu
Satellite interference source location system is one of the important means of satellite communication anti-interference. High-precision satellite interference source positioning technology can accurately lock the location of the interference source and take measures to remove the interference. Time difference of arrival (TDOA) parameter estimation is a key link in the satellite interference source location system, and the accuracy of TDOA parameter estimation directly affects the location accuracy. This paper proposes a new TDOA parameter estimation algorithm that combines variational model decomposition (VMD) and wavelet threshold denoising (WTD). Firstly, the signal is adaptively decomposed into multiple components through the VMD algorithm to ensure the preservation of the original signal during the denoising process, then an improved WTD algorithm is used to remove the influence of noise in the satellite reception signal. Finally, accurate TDOA parameters are obtained. Numerical simulations show that the accuracy of the improved algorithm are better than conventional methods, thereby indirectly improving the accuracy of satellite interference source location.

Qiangwang Shen, Meng Ding, Shuqin Li, Wentao Du, Wenlong Zhao
Tibetan Jiuqi is a two-person chess type of Chinese ethnic minorities. In 2019, it was listed as one of the chess types of China Computer Game Championship. There are relatively few researches on Jiuqi's game strategy at home and abroad. The layout of the pieces of Jiuqi is generally divided into three stages: the opening, the middle game, and the endgame. This article is mainly based on the rules of the game to study the shape of the game in the opening and middle games. In the opening stage, the opening library is used to assist the game. In the middle stage, a strategy of forming a chess shape is proposed. This strategy is based on a single Dalian and further derives a more aggressive and flexible chess shape on this basis. The experimental results show that the strategy proposed in this article is effective.

In this paper, a complete solution of virtual experiments is proposed which includes both overall design and module design. The overall design of the virtual experiment can be divided into three modules i.e. hardware platform design, software platform design, and unified access portal design, which are all illustrated. In the end, the results of virtual experiments are shown. These steps, which should require the generation of the final output from the styled paper, are mentioned here in this paragraph. Firstly, users have to run "Reference Numbering" from the "Reference Elements" menu and this is the first step to start the bibliography marking (it should be clicked while keeping the cursor at the beginning of the reference list). After the marking is complete, the reference element runs all the options under the "Cross Linking" menu.
随着人工智能、虚拟现实和多媒体技术的发展,以电子学习为目的的数字化交互学习资源层出不穷,其中虚拟实验起着至关重要的作用。它不仅为学习者提供了一种先进的学习工具,而且为学习者提供了一个具有高质量学习资源的开放平台,供学习者进行研究性学习、自主实验和创新实践。这种方法提高了人才培养的质量,为实践教学和实验室建设的改革增添了额外的活力和动力。本文提出了一个完整的虚拟实验方案,包括总体设计和模块设计。虚拟实验的总体设计分为硬件平台设计、软件平台设计和统一接入门户设计三个模块,并进行了说明。最后给出了虚拟实验的结果。这些步骤需要生成样式论文的最终输出,在这一段中有提到。首先,用户必须在“参考书目”菜单中运行“参考书目编号”,这是开始书目标记的第一步(要在鼠标停留在参考书目列表开头的情况下点击)。标记完成后,参考元素将运行“交叉链接”菜单下的所有选项。
