In the contemporary era of data-driven processes, addressing the challenge of processing vast volumes of data has become a pressing concern. With the rapid advancement of computer science and information technology, data processing efficiency has significantly improved. Within this expansive domain, three prominent clustering techniquesnamely, K-Means clustering, spectral clustering, and Density-based spatial clustering of applications with noise (DBSCAN)have assumed pivotal roles due to their versatility and effectiveness. This essay embarks on a systematic examination of these three methods, deconstructing their fundamental principles and navigating through their practical applications.

Fully homomorphic encryption (FHE) in privacy-preserving machine learning (PPML) is a current area of research value, aiming to achieve the protection of users private data by applying the concept of full homomorphic encryption to machine learning privacy preservation. The integration of the two involves extensive model modifications and performance issues. The current difficulties mainly focus on how to improve encryption efficiency through hardware or software, and how to apply homomorphic encryption to neural network models such as RNN that process sequence data. This paper introduces this complex research field, outlines two machine learning service models (MLaas and AIaas) that are concerned by the industry, summarizes the most advanced research technologies based on these two models in recent years, and discusses the technical difficulties and future research directions. As a difficult problem that has never been overcome in cryptography in recent decades, homomorphic technology has received extensive attention from experts and scholars and ushered in new opportunities in the current explosive development of machine learning.

The development of international trade depends to a large extent on the progress of international logistics. However, international logistics cannot exist independently of international trade. Without goods provided by international trade, international logistics loses its foundation. Therefore, in order to accurately assess the demand for international logistics, it is necessary to have a detailed understanding of the development of international trade and to predict its future trends accordingly. In this work, we utilize backpropagation neural networks to predict trends and needs in international trade logistics. Specifically, we build a multi-layer perceptron model, which selects a variety of input variables such as goods circulation, economic indicators, trade policies, and seasonal factors. By training this model, it is possible to effectively learn and capture the complex relationships that affect international trade logistics from historical data. In the experimental analysis, the model has been repeatedly trained and adjusted, and finally demonstrated high accuracy and reliability.
国际贸易的发展在很大程度上取决于国际物流的进步。然而,国际物流不能脱离国际贸易而独立存在。没有国际贸易提供的货物,国际物流就失去了基础。因此,要准确评估国际物流的需求,就必须详细了解国际贸易的发展情况,并据此预测其未来的发展趋势。在这项工作中,我们利用反向传播神经网络来预测国际贸易物流的趋势和需求。具体来说,我们建立了一个多层感知器模型,该模型选择了多种输入变量,如货物流通、经济指标、贸易政策和季节性因素等。通过训练该模型,可以从历史数据中有效地学习和捕捉影响国际贸易物流的复杂关系。在实验分析中,该模型经过反复训练和调整,最终表现出较高的准确性和可靠性。

In modern communication technology, people have higher and higher requirements for communication quality because the data transmission based on digital signal is better than the transmission of analog signal, so the transmission of digital signal becomes more and more important. DPSK, as an intermediate mode of digital modulation, has the advantages of high bandwidth utilization, low bit error rate and easier implementation, and has been widely concerned by people. This paper will compare DPSK with other digital modulation, analyze the advantages of DPSK and predict the future development prospects of DPSK.

Conditional Generative Adversarial Networks (cGANs) have revolutionized digital art by enabling the creation of high-quality, artistically coherent images guided by conditional inputs. This paper examines key factors influencing the performance of cGANs, including the quality of training data, network architecture improvements, and loss function optimization. We introduce a mathematical model to quantify training data quality, emphasizing dataset diversity, data augmentation, and cleaning. Network architectural enhancements such as residual connections, attention mechanisms, and progressive growing are explored for their impact on image quality. Additionally, we discuss the integration of conditional inputs, such as labels and textual descriptions, for precise content control. Challenges in balancing realism with artistic expression, managing mode collapse, and interpreting conditional inputs are also addressed. This study provides a comprehensive framework for enhancing cGAN-generated artworks, offering insights into applications in personalized art generation, art restoration, and collaborative art projects.

Target detection from the perspective of UAV has great potential in the field of urban regulation, limited by the dense small targets, severe environmental obstructions, camera shake, and changes in lighting conditions in the aerial view of drones, the existing object detection algorithms cannot effectively undertake this task. This paper introduces two lightweight feature extraction modules based on YOLOv5, which are C3-Faster with PConv and COT3 with transformer structure. Meanwhile, an extra small detection head is added to the output layer. These approaches enhance accuracy while maintaining the advantages of being lightweight and easy to deploy. The ablation experiments and comparative experiments are designed to verify the effectiveness of these modules. The algorithm presented in this paper can be deployed into embedded systems of small UAVs to assist UAVs in completing various regulatory tasks in complex urban scenarios.
无人机视角下的目标检测在城市监管领域具有巨大潜力,受限于无人机航拍视角下密集的小目标、严重的环境障碍物、相机抖动、光照条件变化等因素,现有的目标检测算法无法有效承担这一任务。本文介绍了两种基于 YOLOv5 的轻量级特征提取模块,分别是带有 PConv 的 C3-Faster 和带有变压器结构的 COT3。同时,在输出层增加了一个额外的小型检测头。这些方法在提高精度的同时,还保持了轻便和易于部署的优点。本文设计了烧蚀实验和对比实验来验证这些模块的有效性。本文介绍的算法可部署到小型无人机的嵌入式系统中,以协助无人机在复杂的城市场景中完成各种监管任务。

Meanwhile, an extra small detection head is added to the output layer. These approaches enhance accuracy while maintaining the advantages of being lightweight and easy to deploy. The ablation experiments and comparative experiments are designed to verify the effectiveness of these modules. The algorithm presented in this paper can be deployed into embedded systems of small UAVs to assist UAVs in completing various regulatory tasks in complex urban scenarios.","PeriodicalId":502253,"journal":{"name":"Applied and Computational Engineering","volume":"12 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141804454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to 2023, over 200 million people worldwide are visually impaired. The needs of people with visual impairments receive scant attention in todays world. Most of them cannot walk independently on Crowded thoroughfares. There are still some challenges in developing assistive devices for the visually impaired. This paper focuses on a classification system within the earphone worn on the ear that can distinguish between different sounds and can be located by the Sharpless of the sound waves. The proposed method comprises two main modules: the first is to transfer the audio signals to Spectrograms, which is done in Python, and then a trained Convolutional Neural Network (CNN) is used in Matlab to identify different types of sounds. When tested in a real-life environment, this system proved useful and accurate in identifying dangerous signals. This innovation is intended to provide them with the optimal time to evacuate dangerous areas, ensuring their safety.
到 2023 年,全球将有超过 2 亿人视力受损。在当今世界,视障人士的需求很少受到关注。他们中的大多数人无法在拥挤的大街上独立行走。为视障人士开发辅助设备仍面临一些挑战。本文的重点是在佩戴在耳朵上的耳机内建立一个分类系统,该系统可以区分不同的声音,并可以通过声波的夏普定位。所提议的方法包括两个主要模块:首先是将音频信号转换为频谱图,这是在 Python 中完成的,然后在 Matlab 中使用训练有素的卷积神经网络(CNN)来识别不同类型的声音。在实际环境中进行测试时,该系统被证明在识别危险信号方面非常有用和准确。这项创新旨在为他们提供撤离危险区域的最佳时机,确保他们的安全。
