Mobile edge caching (MEC) is a promising technology to alleviate traffic congestion in the network. Current studies explored deep reinforcement learning (DRL)-based MEC methods. These methods consider the dynamics of the request size to maximize the cache hit rate. However, they usually ignored the potential request relationships among contents. Two contents with a strong relationship are usually requested sequentially. Inspired by this assumption, this paper proposes a relationship-enhanced content caching algorithm using DRL, named RECC. Our RECC infers user preferences by mining the request relationships among contents. In this work, the relationships are modeled as request sequences, and the request features are learned by using graph embedding. These features will be used as input of state in our DRL-based algorithm. We utilize the Wolpertinger architecture to solve the limitation of large discrete action space. The simulation results indicate that our RECC outperformed the traditional cache policies and state-of-the-art DRL-based method in cache hit rate. Furthermore, the proposed RECC has advantages in long-term stability in the environment where content popularity changes dynamically, and also has a higher cache hit rate when handling the requests with number changes dynamically.
移动边缘缓存(MEC)是一种很有前途的缓解网络流量拥塞的技术。目前的研究探索了基于深度强化学习(DRL)的MEC方法。这些方法考虑请求大小的动态变化,以最大限度地提高缓存命中率。然而,它们通常忽略了内容之间潜在的请求关系。通常顺序请求具有强关系的两个内容。受此假设的启发,本文提出了一种使用DRL的关系增强内容缓存算法,称为RECC。我们的RECC通过挖掘内容之间的请求关系来推断用户偏好。在这项工作中,将关系建模为请求序列,并通过图嵌入来学习请求特征。这些特征将被用作我们基于drl的算法的状态输入。我们利用Wolpertinger架构来解决大离散动作空间的限制。仿真结果表明,RECC在缓存命中率方面优于传统的缓存策略和最先进的基于drl的方法。此外,所提出的RECC在内容流行度动态变化的环境中具有长期稳定性的优点,并且在处理数量动态变化的请求时具有更高的缓存命中率。

Determination of the Mechanical Origination of Wheel-Rail Rolling Noise Based on Spectrum Analysis 基于频谱分析的轮轨滚动噪声机械来源的确定

Acoustic emission technology has a great advantage over existing nondestructive technologies for real-time inspection, which will significantly improve the efficiency of wheel/rail defect detection. However, wheel-rail rolling noise impedes the application of acoustic emission technology in on-line operation, especially in high-speed or heavy-load condition. The key problem lies in that current researches haven’t developed adequate knowledge of the noise, making it difficult to gain the defect signal under the strong noise. To study mechanical originations of the noise and reveal its intrinsic properties, a spectral analysis method is proposed based on a fractal description of rough surfaces. Power spectra of the surface and those of the noise, as well as the relation of their fractal dimensions, are investigated. Then, under the instruction of spectral distributions of microscopic mechanical behaviors, the noise originations and influence of the vehicle speed are determined. It is found that the noise is generated based on the surface topography, while sliding friction, particle behavior, and abrasive wear are the main mechanical sources. The sliding friction dominates among the three behaviors. The speed promotes all the behaviors and then enhances the power level, while its effects on the sliding friction is relatively severer. The work offers a theoretical basis and mechanical explanation for the noise, which provides further guidance for the real-time detection of defect signals.
声发射技术在实时检测方面比现有的无损检测技术有很大的优势,将显著提高轮轨缺陷检测的效率。然而,轮轨滚动噪声阻碍了声发射技术在在线运行中的应用,特别是在高速或重载工况下。关键问题在于目前的研究对噪声的认识不够,在强噪声下难以获得缺陷信号。为了研究噪声的力学来源并揭示其固有特性,提出了一种基于粗糙表面分形描述的谱分析方法。研究了表面的功率谱和噪声的功率谱及其分形维数的关系。然后,在微观力学行为谱分布的指导下,确定噪声的来源和车速对噪声的影响。研究发现,噪声是基于表面形貌产生的,而滑动摩擦、颗粒行为和磨粒磨损是主要的机械来源。在三种行为中,滑动摩擦占主导地位。速度对这些行为都有促进作用,进而提高动力水平,但对滑动摩擦的影响相对较大。该工作为噪声提供了理论基础和力学解释,为缺陷信号的实时检测提供了进一步的指导。

ASHN for Multi-Human Pose Estimation 多人体姿态估计的ASHN算法
Pub Date : 2022-12-09 DOI: 10.1109/ACAIT56212.2022.10137930

Due to the diversity of human body posture, there are problems such as occlusion of key points, difference of target scale and background blur among people. Therefore, multi-human pose estimation is still a challenging task. The existing deep learning-based multi-body pose estimation methods are mainly divided into top-down and bottom-up, but most of them do not make full use of local features in the network. In this paper, convolutional block attention module(CBAM) and Focal L2 Loss were used to process the context information of convolutional neural network and consolidate local features. Specifically, we propose attention-containing stacked hourglass network (ASHN). ASHN is based on a stacked hourglass network, with the addition of a convolutional block attention module (CBAM) module to improve performance, combined with Focal L2 Loss in the model. Compared with the existing methods, our method achieves competitive performance, achieving 66.8% AP, 72.1% AP75 and 65.4% APM on COCO data sets.
由于人体姿态的多样性,人与人之间存在关键点遮挡、目标尺度差异、背景模糊等问题。因此,多人体姿态估计仍然是一项具有挑战性的任务。现有的基于深度学习的多体姿态估计方法主要分为自顶向下和自底向上两种,但大多数方法都没有充分利用网络中的局部特征。本文采用卷积块注意模块(convolutional block attention module, CBAM)和Focal L2 Loss对卷积神经网络的上下文信息进行处理,巩固局部特征。具体来说,我们提出了包含注意力的堆叠沙漏网络(ASHN)。ASHN基于堆叠沙漏网络,增加了卷积块注意模块(CBAM)模块以提高性能,并结合了模型中的Focal L2 Loss。与现有方法相比,我们的方法在COCO数据集上实现了66.8%的AP、72.1%的AP75和65.4%的APM,具有较强的竞争力。

When consumers choose to buy clothing online, virtual try-on technology can provide them with a better shopping experience. The optimization of virtual try-on technology not only helps consumers to evaluate the selected clothing, but also can improve the profit for merchants. However, the traditional virtual try-on technology has problems such as high cost, image distortion, and deviation of clothing style. In order to solve the above problems, this paper proposes a virtual try-on model with enhanced feature representation capability. Through the improved residual block of Squeeze-and-Excitation Networks (SENet) and the style encoding module introduced by the Pyramid Squeeze Attention (PSA) module, our model enriches the content and style information, strengthens the representation ability of features, and the reconstructed image preserves the more details. Compared with related work, we improve the structural similarity measure by 1.1% and the Inception Score by 10.1%. It is demonstrated that our model can reconstruct more accurate and realistic images.

Artificial intelligence (AI) is trained with data, especially texts, numbers, images, videos and music on Internet. These data all together across time and space make a collective memory of the world. The latest large-scale AI models give people a chance to create out of a large pool of this collective memory, which they won’t be able to access before, and communicate with AI in both human natural language and the unique machine supported ways. As demonstrated and discussed in this paper, effective and efficient workflows can be built up for human and AI to co-create meaningful results based on both the collective memory of the world and the personalized ideas and tastes. This kind of human-AI co-creation has a new force with great potential, and expect a new strategy and philosophy to guide human-AI collaboration.

Fine-grained image classification is very difficult task and there is currently no effective machine learning method yet. Taking the butterfly images as an example, this paper comprehensively studies image classification methods for finegrained and complex images, focusing on improving the existing methods in the four aspects of image preprocessing, feature extraction, feature coding, and classifier design. An effective machine learning method for butterfly classification is established. In the aspect of image preprocessing, we firstly introduce the edge breakpoint connection method to make up for the defect that discontinuous edge can’t extract the target region effectively. In terms of feature extraction, nonseparable Shannon wavelet is used to combine with corner feature, blob feature, edge curvature feature and invariant moment feature selection to further improve the utilization of image information. In the aspect of feature encoding, most features in this paper are encoded by histogram, which increases the classification efficiency, and for histogram encoding features, an improved histogram intersection distance is proposed, which makes it more effective in KNN classifier. Finally, in the classifier design, the Bagging ensemble method is integrated into the parallel KNN classifier. Experiments show the effectiveness and robustness of the proposed method.

Experiments show the effectiveness and robustness of the proposed method.","PeriodicalId":398228,"journal":{"name":"2022 6th Asian Conference on Artificial Intelligence Technology (ACAIT)","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129174271","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}

Optimization in energy-harvesting cognitive radio networks is accomplished by the amalgamation of metaheuristics with wireless networks. The design of an optimized energy-harvesting cognitive radio network (EHCRN) is challenging in the realm of wireless networks. This paper proposes a modified optimization technique rank-based multiobjective antlion optimization (RMOALO) based on antlions that finds an approximate solution to the optimization problem of sensing duration and energy consumption with throughput maximization. The search behavior of antlions is improved thus reaching an optimal solution while considering the constraints on collision and energy. The simulated results obtained in this paper show that the average throughput of the secondary wireless network gets maximized for an optimized sensing duration. The results also demonstrate the effect of spectrum sensing duration on the average harvested energy and average throughput for the energy-sufficient and energy-deficit regions.
能量收集认知无线网络的优化是将元启发式算法与无线网络相结合来实现的。在无线网络领域,优化能量收集认知无线网络(EHCRN)的设计是一个具有挑战性的问题。本文提出了一种改进的基于秩的多目标蚁群优化算法(RMOALO),该算法以吞吐量最大化为目标,寻找感知时间和能量消耗优化问题的近似解。改进蚁群的搜索行为,在考虑碰撞约束和能量约束的情况下得到最优解。仿真结果表明,在优化的感知持续时间下,二级无线网络的平均吞吐量达到最大。结果还表明,频谱感知持续时间对能量充足区和能量不足区平均收获能量和平均吞吐量的影响。

This paper mainly uses the comparative analysis method and the case analysis method to explain the explainable artificial intelligence (XAI) in music. The use of XAI in music is real-time interactive, and the more explainable and transparent, the more accurate it is. Interpretability can occur in or after modeling, and deep learning provides theoretical support for XAI. Professor Nick Bryan-Kinns' team made a breakthrough through experimental research on “XAI+Music” with the difficulties currently being explained by artificial intelligence, XAI technology has been directly applied to the creative AI model, for “XAI+Music” development and innovation provide references and ideas.
