Prompt learning is an effective paradigm that bridges gaps between the pre-training tasks and the corresponding downstream applications. Approaches based on this paradigm have achieved great transcendent results in various applications. However, it still needs to be answered how to design a general-purpose framework based on the prompt learning paradigm for various information extraction tasks. In this article, we propose a novel composable prompt-based generative framework, which could be applied to a wide range of tasks in the field of information extraction. Specifically, we reformulate information extraction tasks into the form of filling slots in pre-designed type-specific prompts, which consist of one or multiple sub-prompts. A strategy of constructing composable prompts is proposed to enhance the generalization ability in data-scarce scenarios. Furthermore, to fit this framework, we transform relation extraction into the task of determining semantic consistency in prompts. The experimental results demonstrate that our approach surpasses compared baselines on real-world datasets in data-abundant and data-scarce scenarios. Further analysis of the proposed framework is presented, as well as numerical experiments conducted to investigate impact factors of performance on various tasks.
即时学习是一种有效的范式,可以弥合预训练任务和相应的下游应用程序之间的差距。基于这种范式的方法在各种应用中取得了卓越的成果。然而,如何为各种信息提取任务设计一个基于即时学习范式的通用框架仍然需要回答。在本文中,我们提出了一种新的基于提示的可组合生成框架,该框架可以应用于信息提取领域的广泛任务。具体来说,我们将信息提取任务重新表述为在预先设计的特定类型提示中填充空位的形式,该提示由一个或多个子提示组成。提出了一种构建可组合提示的策略,以增强数据稀缺场景下的泛化能力。此外,为了适应这个框架,我们将关系提取转换为确定提示中语义一致性的任务。实验结果表明,在数据丰富和数据匮乏的情况下,我们的方法超过了真实世界数据集上的比较基线。对所提出的框架进行了进一步的分析,并进行了数值实验来研究各种任务的性能影响因素。

In this article, we study the problem of differentially private multi-party data sharing, where the involved parties assisted by a semi-honest curator collectively generate a shared dataset while satisfying differential privacy. Inspired by the success of data synthesis with the generative adversarial network (GAN), we propose a novel GAN-based differentially private multi-party data sharing approach named ATLAS. In ATLAS, we extend the original GAN to multiple discriminators, and let each party hold a discriminator while the curator holds a generator. To update the generator without compromising each party's privacy, we decompose the calculation of the generator's gradient and selectively sanitize the discriminators’ responses. Additionally, we propose two methods to improve the utility of shared data, i.e., the collaborative discriminator filtering (CDF) method and the adaptive gradient perturbation (AGP) method. Specifically, the CDF method utilizes trained discriminators to refine synthetic records, while the AGP method adaptively adjusts the noise scale during training to reduce the impact of deferentially private noise on the final shared data. Extensive experiments on real-world datasets validate the superiority of our ATLAS approach.
在这篇文章中,我们研究了差异隐私的多方数据共享问题,其中参与方在半诚实的策展人的协助下共同生成共享数据集,同时满足差异隐私。受生成对抗性网络(GAN)数据合成成功的启发,我们提出了一种新的基于GAN的差分私有多方数据共享方法ATLAS。在ATLAS中,我们将原始GAN扩展到多个鉴别器,并让每一方持有一个鉴别者,而策展人持有一个生成器。为了在不损害各方隐私的情况下更新生成器,我们分解生成器梯度的计算,并选择性地净化鉴别器的响应。此外,我们提出了两种提高共享数据效用的方法,即协作鉴别器滤波(CDF)方法和自适应梯度扰动(AGP)方法。具体而言,CDF方法利用经过训练的鉴别器来细化合成记录,而AGP方法在训练期间自适应地调整噪声规模,以减少不同私有噪声对最终共享数据的影响。在真实世界数据集上进行的大量实验验证了我们的ATLAS方法的优越性。

Missing data pattern identification and recovery (MDIR) is vital for accurate air pollution monitoring. To recover the missing air pollution data, GCN-ST-MDIR, a Graph Convolutional Network (GCN)-based MDIR framework, is proposed to identify daily missing data patterns and automatically select the best recovery method. GCN-ST-MDIR presents four novelties: (1) A new graph construction is developed to improve GCN data representation for MDIR using S-T similarity matrix and domain-specific knowledge (e.g., weekend/weekday). (2) A TL component is used to pre-train LSCE and ILSCE models. (3) A GCN structure outputs a selection indicator to determine the dominant missing pattern for daily input. The pre-trained data recovery model's accuracy is incorporated into the GCN loss function to penalize the wrong indicator. (4) The output of the GCN structure is used as a score to combine LSCE and ILSCE. Results show that the domain-specific S-T regularity and irregularity can be used as the prior information for both GCN and ILSCE/LSCE to enhance feature extraction. Our model considerably improves the recovery performance as compared to the baselines. GCN-ST-MDIR has achieved an accuracy of 88.48% for general missing data recovery with consecutively and sporadically missing data. GCN-ST-MDIR can be extended to many other S-T MDIR challenges.
缺失数据模式识别和恢复(MDIR)对于准确监测空气污染至关重要。为了恢复缺失的空气污染数据,提出了基于图卷积网络(GCN)的MDIR框架GCN- st -MDIR,用于识别每日缺失的数据模式并自动选择最佳恢复方法。GCN- st -MDIR提出了四个新颖之处:(1)利用S-T相似矩阵和领域特定知识(例如,周末/工作日),开发了一种新的图结构,以改进MDIR的GCN数据表示。(2)使用TL组件对LSCE和ILSCE模型进行预训练。(3) GCN结构输出一个选择指标,以确定日常输入的主要缺失模式。将预训练的数据恢复模型的准确性纳入GCN损失函数中,对错误指标进行惩罚。(4)以GCN结构的输出作为评分,将LSCE和ILSCE结合起来。结果表明,域特有的S-T正则性和不规则性可以作为GCN和ILSCE/LSCE的先验信息,以增强特征提取。与基线相比,我们的模型大大提高了恢复性能。GCN-ST-MDIR对于连续和零星缺失数据的一般缺失数据恢复准确率达到了88.48%。GCN-ST-MDIR可以扩展到许多其他S-T MDIR挑战。

3D semi-supervised medical image segmentation is extremely essential in computer-aided diagnosis, which can reduce the time-consuming task of performing annotation. The challenges with current 3D semi-supervised segmentation algorithms includes the methods, limited attention to volume-wise context information, their inability to generate accurate pseudo labels and a failure to capture important details during data augmentation. This article proposes a dual uncertainty-guided mixing consistency network for accurate 3D semi-supervised segmentation, which can solve the above challenges. The proposed network consists of a Contrastive Training Module which improves the quality of augmented images by retaining the invariance of data augmentation between original data and their augmentations. The Dual Uncertainty Strategy calculates dual uncertainty between two different models to select a more confident area for subsequent segmentation. The Mixing Volume Consistency Module that guides the consistency between mixing before and after segmentation for final segmentation, uses dual uncertainty and can fully learn volume-wise context information. Results from evaluative experiments on brain tumor and left atrial segmentation shows that the proposed method outperforms state-of-the-art 3D semi-supervised methods as confirmed by quantitative and qualitative analysis on datasets. This effectively demonstrates that this study has the potential to become a medical tool for accurate segmentation. Code is available at: https://github.com/yang6277/DUMC.
三维半监督医学图像分割在计算机辅助诊断中至关重要,可以减少耗时的注释任务。当前的3D半监督分割算法面临的挑战包括方法、对体积上下文信息的关注有限、无法生成准确的伪标签以及无法在数据增强过程中捕捉重要细节。本文提出了一种用于精确三维半监督分割的双不确定性引导混合一致性网络,可以解决上述挑战。所提出的网络由对比训练模块组成,该模块通过保持原始数据与其增强之间的数据增强不变性来提高增强图像的质量。双重不确定性策略计算两个不同模型之间的双重不确定性,以选择一个更有信心的区域进行后续分割。混合体积一致性模块指导分割前后混合的一致性,以进行最终分割,使用双重不确定性,并可以完全学习体积上下文信息。脑肿瘤和左心房分割的评估实验结果表明,通过对数据集的定量和定性分析,所提出的方法优于最先进的3D半监督方法。这有效地证明了这项研究有潜力成为精确分割的医疗工具。代码位于:https://github.com/yang6277/DUMC.

The Internet of Things, privacy, and technical constraints increase the demand for edge-based data-driven services, which is one of the major goals of Industry 4.0 and Society 5.0. Big data analysis (BDA) is the preferred approach to unleash hidden knowledge. However, BDA consumes excessive resources and time. These limitations hamper the meaningful adoption of BDA, especially the time and situation critical edge use cases, and hinder the goals of Industry 4.0 and Society 5.0. Automating the BDA process at the edge is a cognitive approach to address the aforementioned concerns. Data science workflow is an indispensable challenge for successful automation. Therefore, we conducted a systematic literature survey on data science workflow platforms as the first contribution. Moreover, we learned that the BDA workflow depends on diversified constraints and undergoes rigorous data-mining stages. These caused an increase in the solution space, dynamic constraints, complexity issues, and NP-hardness of BDA workflow. Graphplan is a heuristic AI-planning technique that can address concerns associated with BDA workflow. Therefore, as the second contribution, we adopted the graphplan to generate a workflow for edge-based BDA automation. Experiments demonstrate that the proposed method achieved our objectives.

The exploration of self-supervised information mining of heterogeneous datasets has gained significant traction in recent years. Heterogeneous graph neural networks (HGNNs) have emerged as a highly promising method for handling heterogeneous information networks (HINs) due to their superior performance. These networks leverage aggregation functions to convert pairwise relations-based features from raw heterogeneous graphs into embedding vectors. However, real-world HINs contain valuable higher-order relations that are often overlooked but can provide complementary information. To address this issue, we propose a novel method called Self-supervised Nodes-Hyperedges Embedding (SNHE), which leverages hypergraph structures to incorporate higher-order information into the embedding process of HINs. Our method decomposes the raw graph structure into snapshots based on various meta-paths, which are then transformed into hypergraphs to aggregate high-order information within the data and generate embedding representations. Given the complexity of HINs, we develop a dual self-supervised structure that maximizes mutual information in the enhanced graph data space, guides the overall model update, and reduces redundancy and noise. We evaluate our proposed method on various real-world datasets for node classification and clustering tasks, and compare it against state-of-the-art methods. The experimental results demonstrate the efficacy of our method. Our code is available at https://github.com/limengran98/SNHE.
近年来,对异构数据集的自监督信息挖掘的探索得到了极大的关注。异构图神经网络(hgnn)由于其优越的性能而成为处理异构信息网络(HINs)的一种很有前途的方法。这些网络利用聚合函数将基于成对关系的特征从原始异构图转换为嵌入向量。然而,现实世界的HINs包含有价值的高阶关系,这些关系经常被忽视,但可以提供补充信息。为了解决这个问题,我们提出了一种新的方法,称为自监督节点-超边嵌入(SNHE),它利用超图结构将高阶信息融入到HINs的嵌入过程中。我们的方法将原始图结构分解为基于各种元路径的快照,然后将其转换为超图,以聚合数据中的高阶信息并生成嵌入表示。鉴于HINs的复杂性,我们开发了一种双重自监督结构,该结构在增强的图数据空间中最大化互信息,指导整体模型更新,并减少冗余和噪声。我们在各种真实世界的数据集上评估了我们提出的方法,用于节点分类和聚类任务,并将其与最先进的方法进行比较。实验结果证明了该方法的有效性。我们的代码可在https://github.com/limengran98/SNHE上获得。

Clustering a big distributed dataset of hundred gigabytes or more is a challenging task in distributed computing. A popular method to tackle this problem is to use a random sample of the big dataset to compute an approximate result as an estimation of the true result computed from the entire dataset. In this paper, instead of using a single random sample, we use multiple random samples to compute an ensemble result as the estimation of the true result of the big dataset. We propose a distributed computing framework to compute the ensemble result. In this framework, a big dataset is represented in the RSP data model as random sample data blocks managed in a distributed file system. To compute the ensemble clustering result, a set of RSP data blocks is randomly selected as random samples and clustered independently in parallel on the nodes of a cluster to generate the component clustering results. The component results are transferred to the master node, which computes the ensemble result. Since the random samples are disjoint and traditional consensus functions cannot be used, we propose two new methods to integrate the component clustering results into the final ensemble result. The first method uses component cluster centers to build a graph and the METIS algorithm to cut the graph into subgraphs, from which a set of candidate cluster centers is found. A hierarchical clustering method is then used to generate the final set of $k$ cluster centers. The second method uses the clustering-by-passing-messages method to generate the final set of $k$ cluster centers.

在分布式计算中,对数百GB或更多的大型分布式数据集进行聚类是一项具有挑战性的任务。解决这个问题的一种流行方法是使用大数据集的随机样本来计算近似结果,作为从整个数据集计算的真实结果的估计。在本文中,我们使用多个随机样本来计算集合结果,而不是使用单个随机样本,作为对大数据集真实结果的估计。我们提出了一个分布式计算框架来计算集成结果。在这个框架中,大数据集在RSP数据模型中表示为分布式文件系统中管理的随机样本数据块。为了计算集合聚类结果,随机选择一组RSP数据块作为随机样本,并在集群的节点上并行独立聚类,以生成分量聚类结果。分量结果被传输到主节点,主节点计算集合结果。由于随机样本是不相交的,并且不能使用传统的一致性函数,我们提出了两种新的方法来将分量聚类结果集成到最终的集成结果中。第一种方法使用组件聚类中心来构建图,并使用METIS算法将图切割成子图,从子图中找到一组候选聚类中心。然后使用分层聚类方法来生成最终的$k$k聚类中心集合。第二种方法使用通过传递消息进行聚类的方法来生成$k$k个聚类中心的最终集合。最后,使用$k$k-means算法将整个数据集分配到$k$k个聚类中。实验在合成数据集和真实世界数据集上进行。结果表明,新的集成聚类方法比比较方法性能更好,并且分布式计算框架在对大数据集进行聚类时是高效和可扩展的。

A popular method to tackle this problem is to use a random sample of the big dataset to compute an approximate result as an estimation of the true result computed from the entire dataset. In this paper, instead of using a single random sample, we use multiple random samples to compute an ensemble result as the estimation of the true result of the big dataset. We propose a distributed computing framework to compute the ensemble result. In this framework, a big dataset is represented in the RSP data model as random sample data blocks managed in a distributed file system. To compute the ensemble clustering result, a set of RSP data blocks is randomly selected as random samples and clustered independently in parallel on the nodes of a cluster to generate the component clustering results. The component results are transferred to the master node, which computes the ensemble result. Since the random samples are disjoint and traditional consensus functions cannot be used, we propose two new methods to integrate the component clustering results into the final ensemble result. The first method uses component cluster centers to build a graph and the METIS algorithm to cut the graph into subgraphs, from which a set of candidate cluster centers is found. A hierarchical clustering method is then used to generate the final set of \u0000<inline-formula><tex-math>$k$</tex-math></inline-formula>\u0000 cluster centers.

Machine learning has been used in facial beauty prediction studies. However, the integrity of facial geometric information is not considered in facial aesthetic feature extraction, and the impact of other facial attributes (expression) on aesthetics. We propose a novel multi-feature fusion facial aesthetic analysis framework (NMFA) to overcome this problem. First, we designed a facial shape feature, which is an intuitive, visual quantitative description, based on B-spline. Second, we designed a representative low-dimensional facial structural feature to establish the theoretical basis of the facial structure, based on facial aesthetic structure and expression recognition theory. Next, we designed texture and holistic features based on Gabor and VGG-face network. Finally, we used a multi-feature fusion strategy to fuse them for aesthetic evaluation. Experiments were conducted on four databases. The results revealed that the proposed method realizes the visualization of facial shape features, enriches geometric information, solves the problem of lack of facial geometric information and difficulty to understand, and achieves excellent performance with fewer parameters.
机器学习已被用于面部美容预测研究。然而,在面部美学特征提取中没有考虑面部几何信息的完整性,以及其他面部属性(表情)对美学的影响。为了克服这一问题,我们提出了一种新的多特征融合人脸美学分析框架(NMFA)。首先,我们设计了一个基于B样条的人脸形状特征,这是一个直观、可视化的定量描述。其次,基于人脸美学结构和表情识别理论,设计了具有代表性的低维人脸结构特征,为人脸结构的研究奠定了理论基础。接下来,我们设计了基于Gabor和VGG人脸网络的纹理和整体特征。最后,我们使用了多特征融合策略来融合它们进行美学评价。实验在四个数据库上进行。结果表明,该方法实现了人脸形状特征的可视化,丰富了几何信息,解决了人脸几何信息缺乏和难以理解的问题,并以较少的参数获得了优异的性能。

A data marketplace is an online venue that brings data owners, data brokers, and data consumers together and facilitates commoditisation of data amongst them. Data pricing, as a key function of a data marketplace, demands quantifying the monetary value of data. A considerable number of studies on data pricing can be found in literature. This article attempts to comprehensively review the state-of-the-art on existing data pricing studies to provide a general understanding of this emerging research area. Our key contribution lies in a new taxonomy of data pricing studies that unifies different attributes determining data prices. The basis of our framework categorises these studies by the kind of market structure, be it sell-side, buy-side, or two-sided. Then in a sell-side market, the studies are further divided by query type, which defines the way a data consumer accesses data, while in a buy-side market, the studies are divided according to privacy notion, which defines the way to quantify privacy of data owners. In a two-sided market, both privacy notion and query type are used as criteria. We systematically examine the studies falling into each category in our taxonomy. Lastly, we discuss gaps within the existing research and define future research directions.
数据市场是一个在线场所,它将数据所有者、数据代理和数据消费者聚集在一起,并促进他们之间的数据商品化。数据定价作为数据市场的一项关键功能,要求对数据的货币价值进行量化。文献中有相当多关于数据定价的研究。本文试图全面回顾现有数据定价研究的最新进展,以提供对这一新兴研究领域的总体理解。我们的主要贡献在于数据定价研究的新分类,统一了决定数据价格的不同属性。我们框架的基础是根据市场结构的类型对这些研究进行分类,无论是卖方、买方还是双边。然后,在卖方市场中,研究进一步按照查询类型进行划分,查询类型定义了数据消费者访问数据的方式,而在买方市场中,研究根据隐私概念进行划分,隐私概念定义了量化数据所有者隐私的方式。在双边市场中,隐私概念和查询类型都被用作标准。我们系统地检查属于我们分类法中每一类的研究。最后,讨论了现有研究的不足,并明确了未来的研究方向。

In this article, we study the robust tensor completion problem in three-dimensional image data, where only partial entries are available and the observed tensor is corrupted by Gaussian noise and sparse noise simultaneously. Compared with the existing tensor nuclear norm minimization for the low-rank component, we propose to use the transformed tensor nuclear norm to explore the global low-rankness of the underlying tensor. Moreover, the plug-and-play (PnP) deep prior denoiser is incorporated to preserve the local details of multi-dimensional images. Besides, the tensor $ell _{1}$ norm is utilized to characterize the sparseness of the sparse noise. A symmetric Gauss-Seidel based alternating direction method of multipliers is designed to solve the resulting model under the PnP framework with deep prior denoiser. Extensive numerical experiments on hyperspectral and multispectral images, videos, color images, and magnetic resonance image datasets are conducted to demonstrate the superior performance of the proposed model in comparison with several state-of-the-art models.
在本文中,我们研究了三维图像数据中的鲁棒张量补全问题,其中观测到的张量同时被高斯噪声和稀疏噪声破坏。与现有的针对低秩分量的张量核范数最小化方法相比,我们提出使用变换后的张量核范数来探索底层张量的全局低秩性。此外,采用即插即用(PnP)深度先验去噪来保留多维图像的局部细节。此外,利用张量$ well _{1}$ _1范数表征稀疏噪声的稀疏性。在带深度先验去噪的PnP框架下,设计了一种基于高斯-赛德尔的对称交替方向乘子方法来求解得到的模型。在高光谱和多光谱图像、视频、彩色图像和磁共振图像数据集上进行了大量的数值实验,以证明与几种最先进的模型相比,所提出的模型具有优越的性能。
