可进入的模型可以通过在表示理论和特征领域的语言中制定均衡性要求来提供非常通用和灵活的均衡性，这对许多视觉任务都是有效的。但是，由于3D旋转的数学更复杂，因此在2D情况下得出3D旋转模型要困难得多。在这项工作中，我们采用部分差分运算符（PDOS）来模型3D滤波器，并得出了通用的可检测3D CNN，称为PDO-S3DCNNS。我们证明，模棱两可的过滤器受线性约束的约束，可以在各种条件下有效地解决。据我们所知，PDO-S3DCNNS是3D旋转的最通用的CNN，因为它们涵盖了所有$ SO（3）$及其表示的所有常见子组，而现有方法只能应用于特定的组和特定组和表示。广泛的实验表明，我们的模型可以很好地保留在离散域中的均衡性，并且在SHREC'17检索和ISBI 2012分割任务上的表现都超过了以前的网络复杂性。

已经研究了代表文本作为获取自动文本摘要的图形的图形已有十多年了。随着对自然语言处理（NLP）的关注或变压器的发展，可以在文本的图和注意结构之间建立联系。在本文中，整个文本的句子之间的注意力矩阵被用作文本完全连接图的加权相邻矩阵，可以通过预训练的语言模型产生。GCN进一步应用于文本图模型，以分类每个节点并从文本中找出显着句子。在两个典型数据集上的实验结果证明了这一点，我们提出的模型可以与现有模型相比获得竞争成果。

As the COVID-19 pandemic puts pressure on healthcare systems worldwide, the computed tomography image based AI diagnostic system has become a sustainable solution for early diagnosis. However, the model-wise vulnerability under adversarial perturbation hinders its deployment in practical situation. The existing adversarial training strategies are difficult to generalized into medical imaging field challenged by complex medical texture features. To overcome this challenge, we propose a Contour Attention Preserving (CAP) method based on lung cavity edge extraction. The contour prior features are injected to attention layer via a parameter regularization and we optimize the robust empirical risk with hybrid distance metric. We then introduce a new cross-nation CT scan dataset to evaluate the generalization capability of the adversarial robustness under distribution shift. Experimental results indicate that the proposed method achieves state-of-the-art performance in multiple adversarial defense and generalization tasks. The code and dataset are available at https://github.com/Quinn777/CAP.

本文提出了一种新颖的统一特征优化（UFO）范式，用于训练和在现实世界和大规模场景下进行深层模型，这需要集合多个AI功能。不明飞行物的目标是通过对所有任务进行大规模预修。与众所周知的基础模型相比，UFO具有两个不同的重点，即相对较小的模型大小，没有适应性成本：1）UFO以多任务学习方式将广泛的任务挤入中等尺寸的统一模型中并在转移到下游任务时进一步修剪模型大小。 2）不明飞行物不强调转移到新任务。相反，它旨在使修剪模型专门用于一个或多个已经看到的任务。有了这两个特征，UFO为灵活的部署提供了极大的便利，同时保持了大规模预处理的好处。 UFO的一个关键优点是修剪过程不仅可以减少模型的大小和推理消耗，而且还提高了某些任务的准确性。具体而言，UFO考虑了多任务培训，并对统一模型产生了两倍的影响：一些密切相关的任务具有相互利益，而某些任务相互冲突。不明飞行物设法通过新颖的网络体系结构搜索（NAS）方法来减少冲突并保留相互利益。对各种深度表示学习任务（即面部识别，人重新识别，车辆重新识别和产品检索）的实验表明，从UFO中修剪的模型比单件任务训练的对应物更高，但却具有更高的准确性较小的型号大小，验证不明飞行物的概念。此外，UFO还支持发布170亿个参数计算机视觉（CV）基础模型，该模型是该行业中最大的CV模型。

最近有利息线性编程（LP）的一阶方法。在本文中，我们提出了一种使用差异减少的随机算法，并重新启动，用于解决LP等尖锐的原始 - 双重问题。我们表明，所提出的随机方法表现出具有高概率的尖锐实例的线性收敛速率，这提高了现有的确定性和随机算法的复杂性。此外，我们提出了一个有效的基于坐标的随机甲骨文，用于无限制的双线性问题，它具有$ \ Mathcal O（1）$彼得迭代成本并改善总牌数量达到一定的准确性。

尽管概念化已经在语义和知识表示中进行了广泛研究，但找到最准确的概念短语来表征在快速增长的社交媒体上表征文本片段的主要思想仍然具有挑战性。这部分归因于以下事实：大多数知识库都包含世界的一般术语，例如树木和汽车，它们没有定义的力量或对社交媒体应用程序用户不够有趣。另一个原因是，自然语言的复杂性允许使用时态，否定和语法改变语言的逻辑或重点，从而传达了完全不同的含义。在本文中，我们提出了标签，这是一个高质量的概念匹配的数据集，该数据集由10,000个标记的精细概念和网络风格的自然语言句子组成，并从开放域社交媒体中挖出。我们考虑的概念代表了在线用户的趋势兴趣。与标签相关的是这些细粒度概念和实体的概念图，以提供结构上下文信息。我们在标签上评估了广泛的流行神经文本匹配模型以及预先训练的语言模型，并指出他们以最合适的概念标记社交媒体内容的不足。我们进一步提出了一种新颖的图形匹配方法，该方法通过更好地利用概念图中的结构上下文和句子中语义单元之间的逻辑相互作用在句子中通过句法依赖性解析来展示出色的抽象和概括性能。我们开源标签数据集和提出进一步研究的建议方法。

Knowledge graphs (KG) have served as the key component of various natural language processing applications. Commonsense knowledge graphs (CKG) are a special type of KG, where entities and relations are composed of free-form text. However, previous works in KG completion and CKG completion suffer from long-tail relations and newly-added relations which do not have many know triples for training. In light of this, few-shot KG completion (FKGC), which requires the strengths of graph representation learning and few-shot learning, has been proposed to challenge the problem of limited annotated data. In this paper, we comprehensively survey previous attempts on such tasks in the form of a series of methods and applications. Specifically, we first introduce FKGC challenges, commonly used KGs, and CKGs. Then we systematically categorize and summarize existing works in terms of the type of KGs and the methods. Finally, we present applications of FKGC models on prediction tasks in different areas and share our thoughts on future research directions of FKGC.

Unsupervised domain adaptation (UDA) for semantic segmentation is a promising task freeing people from heavy annotation work. However, domain discrepancies in low-level image statistics and high-level contexts compromise the segmentation performance over the target domain. A key idea to tackle this problem is to perform both image-level and feature-level adaptation jointly. Unfortunately, there is a lack of such unified approaches for UDA tasks in the existing literature. This paper proposes a novel UDA pipeline for semantic segmentation that unifies image-level and feature-level adaptation. Concretely, for image-level domain shifts, we propose a global photometric alignment module and a global texture alignment module that align images in the source and target domains in terms of image-level properties. For feature-level domain shifts, we perform global manifold alignment by projecting pixel features from both domains onto the feature manifold of the source domain; and we further regularize category centers in the source domain through a category-oriented triplet loss and perform target domain consistency regularization over augmented target domain images. Experimental results demonstrate that our pipeline significantly outperforms previous methods. In the commonly tested GTA5$\rightarrow$Cityscapes task, our proposed method using Deeplab V3+ as the backbone surpasses previous SOTA by 8%, achieving 58.2% in mIoU.

Given the increasingly intricate forms of partial differential equations (PDEs) in physics and related fields, computationally solving PDEs without analytic solutions inevitably suffers from the trade-off between accuracy and efficiency. Recent advances in neural operators, a kind of mesh-independent neural-network-based PDE solvers, have suggested the dawn of overcoming this challenge. In this emerging direction, Koopman neural operator (KNO) is a representative demonstration and outperforms other state-of-the-art alternatives in terms of accuracy and efficiency. Here we present KoopmanLab, a self-contained and user-friendly PyTorch module of the Koopman neural operator family for solving partial differential equations. Beyond the original version of KNO, we develop multiple new variants of KNO based on different neural network architectures to improve the general applicability of our module. These variants are validated by mesh-independent and long-term prediction experiments implemented on representative PDEs (e.g., the Navier-Stokes equation and the Bateman-Burgers equation) and ERA5 (i.e., one of the largest high-resolution data sets of global-scale climate fields). These demonstrations suggest the potential of KoopmanLab to be considered in diverse applications of partial differential equations.

Different people speak with diverse personalized speaking styles. Although existing one-shot talking head methods have made significant progress in lip sync, natural facial expressions, and stable head motions, they still cannot generate diverse speaking styles in the final talking head videos. To tackle this problem, we propose a one-shot style-controllable talking face generation framework. In a nutshell, we aim to attain a speaking style from an arbitrary reference speaking video and then drive the one-shot portrait to speak with the reference speaking style and another piece of audio. Specifically, we first develop a style encoder to extract dynamic facial motion patterns of a style reference video and then encode them into a style code. Afterward, we introduce a style-controllable decoder to synthesize stylized facial animations from the speech content and style code. In order to integrate the reference speaking style into generated videos, we design a style-aware adaptive transformer, which enables the encoded style code to adjust the weights of the feed-forward layers accordingly. Thanks to the style-aware adaptation mechanism, the reference speaking style can be better embedded into synthesized videos during decoding. Extensive experiments demonstrate that our method is capable of generating talking head videos with diverse speaking styles from only one portrait image and an audio clip while achieving authentic visual effects.
