Metaverse is a collective term for all economic and social activities in the space where the physical world, digital world, and consciousness world are interactively integrated and mutually empowered. The metaverse is the advanced stage of digital civilization and the future formation of human society. The basis for developing metaverse is general digital technologies such as high-performance network, high-performance storage, high-performance computing, high-performance security, and artificial intelligence. On the basis of the above, the key to developing the metaverse lies in researching core technologies such as digital life technologies, trusted collaborative network technologies, natural interaction technologies, ubiquitous operating system technologies, technologies and methods for computational experiments, and theories and technologies for crowd intelligence science. We should take typical metaverse application scenarios as entry points, such as the key fields of agriculture, industry, service industry, military, social governance, and other economic and social areas, to break through key metaverse technologies and implement pilot demonstration projects of metaverse. Through the demonstration, we can systematically promote the application of metaverse in economy and society from point to line, and continuously iterate and evolve the metaverse technology to advance the metaverse to a higher stage. This paper systematically analyzes the current development status and future directions of metaverse from the concept, key technology, and vision of metaverse, paving the way for the subsequent research of metaverse.

Crowd collaboration system, originating from cooperation among animals in nature, is composed of intelligent subjects, characterized by complex dynamic interactions, and has many applications in daily life. In the fields of psychology and computing, scientists have tried to quantify individual intelligence with performance on tasks. In this paper, we explore the main factors affecting group performance for small production factories from the perspective of intelligence. Based on the individual daily efficiency and the average process efficiency, we evaluate individual intelligence level and interaction intensity by integrating group size and efficiency difference, and thus propose crowd intelligence evaluation method. The rationality of the method is analyzed from overall group performance and change in the average individual performance. In the future, the intelligence evaluation method can be applied to more general production scenarios, and the impact of external uncertainty on the intelligence can be studied with simulation to achieve real-time and quantitative optimization of intelligence level of the crowd collaboration system.

With the rapid economic development, megacities have gathered a large number of population and industries, and a series of “urban diseases” have also emerged. To alleviate these problems, various administrative measures have been taken to control population and optimize industrial distribution. Meanwhile, home-purchase restriction (HPR) has been introduced to control the soaring housing prices. Existing research focuses on the impact of policy on its own market, without paying attention to the linkage between markets and spillover effect. We take Beijing, the capital of China, as an example to study the impact of the HPR on the population distribution and industry development of megacities. By analyzing the industry location quotient and population economy matching degree, we conclude that HPR effectively promotes the efficiency of population and industry dispersal, but increases the mismatching between industry and population. City is a typical intelligent system that gathers various intelligent agents, and the development of its population and industry is the fundamental evolution of the system. This paper explores the role of policies in the evolution of urban intelligent systems, and therefore has important theoretical and practical significance for intelligent systems.
随着经济的快速发展,特大城市聚集了大量的人口和产业,一系列的“城市病”也随之出现。为了缓解这些问题,采取了各种行政措施来控制人口和优化产业布局。与此同时,住房购买限制(HPR)已经出台,以控制飙升的房价。现有的研究侧重于政策对自身市场的影响,而没有关注市场与溢出效应之间的联系。我们以中国首都北京为例,研究了HPR对超大城市人口分布和产业发展的影响。通过对产业区位商和人口经济匹配度的分析,我们得出结论:HPR有效地促进了人口和产业的分散效率,但增加了产业与人口的不匹配。城市是一个典型的聚集了各种智能主体的智能系统,其人口和产业的发展是该系统的根本进化。本文探讨了政策在城市智能系统进化中的作用,因此对智能系统具有重要的理论和实践意义。

The evaluation and prediction of credit risk have always been a research hotspot to ensure the healthy and orderly development of the credit market. Most researchers use deep learning to predict credit risk. However, when training data are too small, deep learning models often lead to overfitting. Although we have a large amount of available training data, we often cannot ensure that the data are evenly distributed, which is still not conducive to model training. In addition, deep learning is often difficult to explain, and the unexplained model is often difficult to gain the trust of users, thus reducing the usefulness of the model. To solve these problems, we propose an integrated cross-domain credit default prediction network, called Transfer Light Gradient Boosting Machine (TrLightGBM), based on interpretable integration transfer. This network considers the weight of data from different domains in training and implements cross-domain credit default prediction by adjusting the weight. The experiment shows that our method TrLightGBM not only achieves the interpretability of the model to a certain extent but also has good performance.
信用风险的评估和预测一直是保证信贷市场健康有序发展的研究热点。大多数研究人员使用深度学习来预测信贷风险。然而,当训练数据太小时,深度学习模型往往会导致过拟合。尽管我们有大量可用的训练数据,但我们往往无法确保数据均匀分布,这仍然不利于模型训练。此外,深度学习往往难以解释,无法解释的模型往往难以获得用户的信任,从而降低了模型的有用性。为了解决这些问题,我们提出了一种基于可解释积分转移的跨域信用违约预测网络,称为转移光梯度提升机(TrLightGBM)。该网络在训练中考虑了来自不同领域的数据的权重,并通过调整权重来实现跨领域信用违约预测。实验表明,我们的方法TrLightGBM不仅在一定程度上实现了模型的可解释性,而且具有良好的性能。

Digital music has various characteristics, such as melody, rhythm, timbre, and harmony. According to these characteristics, music can be classified using artificial intelligence (AI). Music can reduce cognitive dissonance and improve memory in humans; however, occasionally, dissonant music can cause negative effects, such as aggravating depression. Therefore, music can be classified using technical methods and used selectively for human mood regulation, sleep improvement, disease relief, and treatment. Herein we present a survey of the fields of music, AI, and health to shed light on the digitization of music. In this survey, we (1) summarize the various characteristic elements of music, such as melody, rhythm, timbre, and harmony; (2) discuss the role of neural networks in classifying music based on these musical characteristics; (3) summarize the positive and negative effects of music with respect to five areas: sleep, memory, attention, mood, and movement; (4) summarize the therapeutic effect of music intervention with respect to various illnesses; and (5) present the future of music therapy as well as provide a few suggestions with respect to music therapy.
数字音乐具有多种特征,如旋律、节奏、音色和和声。根据这些特征,可以使用人工智能(AI)对音乐进行分类。音乐可以减少人类的认知失调,提高记忆力;然而,偶尔,不和谐的音乐会引起负面影响,比如加重抑郁。因此,音乐可以通过技术方法进行分类,并选择性地用于调节人类情绪、改善睡眠、缓解疾病和治疗。在此,我们对音乐、人工智能和健康领域进行了调查,以阐明音乐的数字化。在这项调查中,我们(1)总结了音乐的各种特征元素,如旋律、节奏、音色和和声;(2) 讨论了神经网络在基于这些音乐特征的音乐分类中的作用;(3) 从睡眠、记忆、注意力、情绪和运动五个方面总结音乐的积极和消极影响;(4) 总结音乐干预对各种疾病的治疗效果;以及(5)介绍了音乐治疗的未来,并对音乐治疗提出了一些建议。

Part Deviation Correction Method Based on Geometric Feature Recognition 基于几何特征识别的零件偏差校正方法
Q2 Decision Sciences Pub Date : 2023-09-01 DOI: 10.26599/IJCS.2023.9100005

To realize the automatic loading process of parts, one of the core tasks is to identify the geometric contour of the part's surface and the angular direction. Since the angular direction of each part is not the same when it arrives at the loading position, for example, there are two same types of parts with the same pattern, when they arrive at the loading position, the pattern on one part may be on the right side of the part surface, and the pattern on the other part may be on the left side of the part surface, the gripper of the mechanical arm needs to rotate above the parts in order to grab the parts during each loading process. If the rotation angle is wrong, there will be an impact between the gripper and the parts. Therefore, in order to solve the problem of different angles, this paper proposes a method of parts deviation correction based on geometric features. In this work, firstly, the acquired image is preprocessed, the image background is separated, and the geometric features of the parts are obtained. Then edge detection is used to obtain the set of edge pixels to obtain the contour in the image. Finally, the image moment and measurement model are used to output angular direction. Through 500 repeated detection experiments, the results show that this method can perform better angular direction correction. The maximum angular direction difference is 0.073°, which is 0.856° and 1.793° higher than the Least square method and Hough transform circle detection accuracy, respectively. The average detection time is 1.89 s and is 0.336 s and 1.39 s less than the Least square method and Hough transform circle detection, which meets the requirements of industrial applications.
为了实现零件的自动加载过程,核心任务之一是识别零件表面的几何轮廓和角度方向。由于每个零件到达装载位置时的角度方向不相同,例如,存在具有相同图案的两种相同类型的零件,因此当它们到达装载位置后,一个零件上的图案可以在零件表面的右侧,而另一个零件的图案可以位于零件表面的左侧,机械臂的夹具需要在零件上方旋转,以便在每次装载过程中抓取零件。如果旋转角度错误,夹持器和零件之间会发生碰撞。因此,为了解决不同角度的问题,本文提出了一种基于几何特征的零件偏差校正方法。本文首先对采集的图像进行预处理,分离图像背景,得到零件的几何特征。然后使用边缘检测来获得边缘像素集,从而获得图像中的轮廓。最后,利用图像矩和测量模型输出角度方向。通过500次重复检测实验,结果表明该方法可以进行较好的角方向校正。最大角方向差为0.073°,分别比最小二乘法和霍夫变换圆检测精度高0.856°和1.793°。平均检测时间为1.89s,比最小二乘法和霍夫变换圆检测分别短0.336s和1.39s,满足工业应用的要求。

The study of product maps in e-commerce has garnered significant attention from academics and practitioners, as they provide insights into the relationship between products, such as complementarity and competition. However, existing studies have focused on the perspectives of large manufacturers and retailers, using data from these central sources. This paper adopts a bottom-up approach based on crowd intelligence, with small- and medium-sized e-commerce (SME) sites serving as independent data providers. This approach allows for the decentralized processing of data and enables the aggregation of diverse perspectives and insights from a large number of independent sources. A graph term frequency-inverse document frequency method is proposed, which can measure the similarities of products and build a product map. The method was employed to find a hierarchical community structure using data from over 90 000 products from 52 SME sites. The results showed that products within the same site tend to be distributed across the same community. Our findings can assist e-commerce sites in making informed decisions about pricing and product offerings, leading to more diversified production.
电子商务中的产品地图研究引起了学术界和从业者的极大关注,因为它们深入了解了产品之间的关系,如互补性和竞争性。然而,现有的研究集中在大型制造商和零售商的角度,使用这些中心来源的数据。本文采用了一种基于群体智能的自下而上的方法,中小电子商务(SME)网站作为独立的数据提供商。这种方法允许对数据进行分散处理,并能够汇集来自大量独立来源的不同观点和见解。提出了一种图项频率逆文档频率方法,该方法可以测量产品的相似性并建立产品映射。该方法使用来自52个中小企业网站的900000多种产品的数据来寻找分层社区结构。结果表明,同一网站内的产品往往分布在同一社区。我们的研究结果可以帮助电子商务网站在定价和产品供应方面做出明智的决定,从而实现更多元化的生产。

However, existing studies have focused on the perspectives of large manufacturers and retailers, using data from these central sources. This paper adopts a bottom-up approach based on crowd intelligence, with small- and medium-sized e-commerce (SME) sites serving as independent data providers. This approach allows for the decentralized processing of data and enables the aggregation of diverse perspectives and insights from a large number of independent sources. A graph term frequency-inverse document frequency method is proposed, which can measure the similarities of products and build a product map. The method was employed to find a hierarchical community structure using data from over 90 000 products from 52 SME sites.

Increasing the number, diversity, or uniformity of opinions in a group does not necessarily imply that those opinions will converge into a single more “intelligent” one, if an objective definition of the term intelligent exists as it applies to opinions. However, a recently developed approach called human-centric functional modeling provides what might be the first general model for individual or collective intelligence. In the case of the collective intelligence of groups, this model suggests how a cacophony of incoherent opinions in a large group might be combined into coherent collective reasoning by a hypothetical platform called “general collective intelligence” (GCI). When applied to solving group problems, a GCI might be considered a system that leverages collective reasoning to increase the beneficial insights that might be derived from the information available to any group. This GCI model also suggests how the collective reasoning ability (intelligence) might be exponentially increased compared to the intelligence of any individual in a group, potentially resulting in what is predicted to be a collective superintelligence.
如果“智能”一词在适用于意见时存在客观定义,那么增加一个群体中意见的数量、多样性或一致性并不一定意味着这些意见会汇聚成一个更“智能”的意见。然而,最近开发的一种称为以人为中心的功能建模的方法提供了可能是个人或集体智能的第一个通用模型。在群体的集体智慧的情况下,该模型表明,一个名为“一般集体智慧”(GCI)的假设平台可能会将一个大群体中不连贯的意见的不和谐声音组合成连贯的集体推理。当应用于解决群体问题时,GCI可能被认为是一个利用集体推理来增加从任何群体可用的信息中获得的有益见解的系统。这个GCI模型还表明,与群体中任何个人的智力相比,集体推理能力(智力)可能会呈指数级增长,从而可能导致被预测为集体超级智能的结果。
