Dunhuang Murals are one of China's intangible cultural heritages, which have received extensive attention. Identifying and classifying the dynasties of ancient murals quickly and accurately is extremely important for the study of Dunhuang Murals and the digital protection and inheritance. A method to classify Dunhuang Murals dynasties based on convolutional neural network (CNN) is proposed in this paper. First, the Dunhuang Murals data set is constructed from the mural materials; then, four convolutional neural network models with different depths and structures are constructed and trained; finally, the network model is tested using the test set and an appropriate classification model is selected. The experimental results show that for the Dunhuang mural image data sets of five different dynasties in this paper,the four models obtain high classification accuracy, and the accuracy of VGG11 and VGG19 reach 96%. Among them,the classification accuracy of murals in the Sui Dynasty and the Five Dynasties and Song Dynasties is lower than that of other dynasties in this paper.

Today, with the strong return of traditional culture, the integration of the two will deeply affect the protection of traditional handicrafts and the field of cultural communication. The industrialized production mode has gradually replaced the labor-intensive production mode, and handicrafts have gradually faded out of the public consumption field. The brain drain is serious, and many handicrafts with a long history have no successors. Under the background of AI(artificial intelligence) empowerment, this paper combines AI with traditional handicraft skills, and makes an in-depth study on the inheritance and dissemination of traditional handicraft skills. On this basis, it further thinks about the relationship between traditional handicraft skills display and experience, and the relationship between technology and experience, and studies the change of design concept from technology-oriented to human experience-oriented in traditional handicraft skills display design, and explores the development trend of experience design concept in future traditional handicraft skills display design. Develop the path and method of innovation, protection and inheritance with the comprehensive digital virtual traditional handicraft skill framework. The integration of AI and traditional culture will inevitably broaden and upgrade the path of inheritance and innovation of traditional handicraft skills, and make it achieve new development.

This paper aims to investigate a fractional order prey predator model with group defense and time delay through differential equation linearization theory and predictor-corrector scheme. In this model, we use the Holling-IV functional response, called Monod-Haldane function, for interactions between prey and predator species. Firstly, the uniqueness of the solution to the initial value problem of this system are proved. Secondly, the existence of equilibrium points is discussed, and the Hopf bifurcation of this system is studied using time lag as the bifurcation parameter. Finally, based on the predictor-corrector scheme, we conduct numerical simulations with corresponding parameters and different time delay parameters to analyze the impact of time delay on dynamics.

Ziheng Qu
In recent years, deep learning models have greatly improved the performance of pedestrian detection and tracking. Although the accuracy of neural network-based modeling methods is high, they often require large computational and storage resource overheads, which makes them difficult to apply to robots with high resource requirements. Pedestrian tracking for robots still faces great challenges in the problems of occlusion, multi-target, and target loss. In this thesis, we focus on solving the problem of real-time pedestrian tracking by lightweight fusion of deep learning target detection models for robots, firstly, through the lightweight YOLO network, we perform pedestrian detection and feature extraction, and then we propose a Gaussian mixture model based feature matching method to construct the target pedestrian tracker, and finally, we use the PID-based control algorithm for real-time control of the robot's motion, and finally realize the real-time pedestrian Tracking. In this thesis, we validate the feature matching method based on the Gaussian mixture model on the ETH dataset, and at the same time, combined with the motion control algorithm, we carry out the actual validation, and the experimental results show that our proposed method can realize the real-time pedestrian tracking.
近年来,深度学习模型大大提高了行人检测和跟踪的性能。基于神经网络的建模方法虽然精度高,但往往需要大量的计算和存储资源开销,因此很难应用于对资源要求较高的机器人。机器人的行人跟踪仍然面临着遮挡、多目标和目标丢失等问题的巨大挑战。在本论文中,我们重点通过轻量级融合机器人深度学习目标检测模型来解决行人实时跟踪问题,首先通过轻量级YOLO网络进行行人检测和特征提取,然后提出基于高斯混合模型的特征匹配方法构建目标行人跟踪器,最后利用基于PID的控制算法对机器人的运动进行实时控制,最终实现行人实时跟踪。在本论文中,我们在 ETH 数据集上验证了基于高斯混合模型的特征匹配方法,同时结合运动控制算法进行了实际验证,实验结果表明我们提出的方法可以实现行人的实时跟踪。

A Computational Linguistic Approach to English Lexicography 英语词汇学的计算语言学方法
Pub Date : 2023-12-21 DOI: 10.62051/wepk6t89
Fan Yang
Focusing on computational linguistic approaches to English linguistics, this research explores how computational methods can be applied to dissect, understand and utilise the English language. We first looked at text analysis and processing, delving into natural language processing techniques such as text categorisation, sentiment analysis and machine translation, and their application to social media and automated text processing. In the area of lexicography and semantics, we explored how techniques such as distributed word vectors, semantic role labelling and sentiment analysis can deepen our understanding of vocabulary and semantics. We highlight the importance of these techniques in natural language processing tasks such as sentiment analysis and information retrieval. In addition, we focus on cross-language comparative and multilingual research, emphasising how big data and cross-language comparative research can reveal similarities and differences between languages and their implications for global linguistics. Finally, we explore corpus linguistics and big data analytics, highlighting the richness of linguistic data and tools they provide for linguistic research. Overall, this study highlights the importance of computational linguistic approaches to English linguistics and how they have transformed the way linguistics is studied and language technology has evolved. Future research trends will continue to drive the further development of computational linguistics methods, leading to a closer integration of linguistics with big data analytics and computational methods, creating more opportunities for the future of the field of linguistics.
本研究以英语语言学的计算语言学方法为重点,探索如何将计算方法应用于剖析、理解和利用英语语言。我们首先关注文本分析和处理,深入研究文本分类、情感分析和机器翻译等自然语言处理技术,以及它们在社交媒体和自动文本处理中的应用。在词汇学和语义学领域,我们探讨了分布式词向量、语义角色标签和情感分析等技术如何加深我们对词汇和语义的理解。我们强调了这些技术在情感分析和信息检索等自然语言处理任务中的重要性。此外,我们还关注跨语言比较和多语言研究,强调大数据和跨语言比较研究如何揭示语言之间的异同及其对全球语言学的影响。最后,我们探讨了语料库语言学和大数据分析,强调了语言数据的丰富性及其为语言学研究提供的工具。总之,本研究强调了计算语言学方法对英语语言学的重要性,以及它们如何改变了语言学的研究方式和语言技术的发展。未来的研究趋势将继续推动计算语言学方法的进一步发展,促使语言学与大数据分析和计算方法更紧密地结合,为语言学领域的未来创造更多机遇。
