在弱光条件下获得的图像将严重影响图像的质量。解决较差的弱光图像质量的问题可以有效地提高图像的视觉质量，并更好地改善计算机视觉的可用性。此外，它在许多领域都具有非常重要的应用。本文提出了基于视网膜的Deanet，以增强弱光图像。它将图像的频率信息和内容信息结合到三个子网络中：分解网络，增强网络和调整网络。这三个子网络分别用于分解，变形，对比度增强和细节保存，调整和图像产生。我们的模型对于所有低光图像都具有良好的良好结果。该模型对公共数据集进行了培训，实验结果表明，就视力和质量而言，我们的方法比现有的最新方法更好。

多文件科学摘要（MDSS）旨在为与主题相关的科学论文群生成连贯和简洁的摘要。此任务需要精确理解纸张内容以及对交叉纸关系的准确建模。知识图为文档传达了紧凑且可解释的结构化信息，这使其非常适合内容建模和关系建模。在本文中，我们提出了KGSUM，这是一个MDSS模型，以编码和解码过程中的知识图为中心。具体而言，在编码过程中，提出了两个基于图的模块，以将知识图信息纳入纸张编码，而在解码过程中，我们通过以描述性句子的形式首先生成摘要的知识图，提出了一个两阶段解码器。 ，然后生成最终摘要。经验结果表明，所提出的体系结构对多XSCIENCE数据集的基准进行了实质性改进。

基于点云的3D单一对象跟踪（3DSOT）吸引了越来越多的注意力。已经取得了许多突破，但我们也揭示了两个严重的问题。通过广泛的分析，我们发现当前方法的预测方式是非持bust的，即暴露了预测得分和实际定位精度之间的错位差距。另一个问题是稀疏点返回将损坏SOT任务的功能匹配过程。基于这些见解，我们介绍了两个新型模块，即自适应改进预测（ARP）和目标知识转移（TKT），以解决它们。为此，我们首先设计了强大的管道来提取区分特征，并使用注意机制进行匹配程序。然后，建议通过汇总所有具有宝贵线索的预测候选人来解决未对准问题。最后，由于稀疏和遮挡问题，TKT模块旨在有效克服不完整的点云。我们称我们的整体框架PCET。通过在Kitti和Waymo Open数据集上进行广泛的实验，我们的模型可以实现最新的性能，同时保持较低的计算消耗。

超声检查广泛用于甲状腺结节（良性/恶性）的临床诊断。但是，准确性在很大程度上取决于放射科医生的经验。尽管已经研究了甲状腺结节识别的深度学习技术。当前的解决方案主要基于静态超声图像，其时间信息有限，并且与临床诊断不一致。本文提出了一种通过详尽的超声视频和钥匙框架进行详尽的探索来自动识别甲状腺结节的新方法。我们首先提出一个检测 - 定位框架，以自动识别每个超声视频中典型结节的临床密钥框架。根据本地化的键框架，我们为甲状腺结节识别开发了一个钥匙框引导的视频分类模型。此外，我们引入了运动注意模块，以帮助网络关注超声视频中的重要帧，这与临床诊断一致。拟议的甲状腺结节识别框架已在临床收集的超声视频上进行了验证，与其他最先进的方法相比，表现出卓越的性能。

我们总结了使用巨大的自动语音识别（ASR）模型的大量努力的结果，该模型使用包含大约一百万小时音频的大型，多样的未标记数据集进行了预训练。我们发现，即使对于拥有数万个小时的标记数据的非常大的任务，预训练，自我培训和扩大模型大小的组合也大大提高了数据效率。特别是，在具有34K小时标记数据的ASR任务上，通过微调80亿个参数预先训练的构象异构体模型，我们可以匹配最先进的（SOTA）性能（SOTA）的性能，只有3％的培训数据和通过完整的训练集可以显着改善SOTA。我们还报告了从使用大型预训练和自我训练的模型来完成一系列下游任务所获得的普遍利益，这些任务涵盖了广泛的语音域，并涵盖了多个数据集大小的大小，包括在许多人中获得SOTA性能公共基准。此外，我们利用预先训练的网络的学会表示，在非ASR任务上实现SOTA结果。

轨迹预测面临着困难，以捕获具有多样性和准确性的未来动力学的多模式性质。在本文中，我们提出了一种分布歧视（DISDIS）方法，可以通过区分潜在分布来预测个性化运动模式。由于每个人的习惯，每个人的运动模式都被个性化，我们的disdis学会了潜在分布来代表不同的运动模式，并通过对比度歧视来优化它。这种分布歧视鼓励潜在分布更具歧视性。我们的方法可以与现有的多模式随机预测模型集成为插件模块，以了解更具歧视性的潜在分布。为了评估潜在分布，我们进一步提出了一个新的度量标准，概率累积最小距离（PCMD）曲线，该曲线累计计算了分类概率的最小距离。对ETH和UCY数据集的实验结果显示了我们方法的有效性。

Feedforward fully convolutional neural networks currently dominate in semantic segmentation of 3D point clouds. Despite their great success, they suffer from the loss of local information at low-level layers, posing significant challenges to accurate scene segmentation and precise object boundary delineation. Prior works either address this issue by post-processing or jointly learn object boundaries to implicitly improve feature encoding of the networks. These approaches often require additional modules which are difficult to integrate into the original architecture. To improve the segmentation near object boundaries, we propose a boundary-aware feature propagation mechanism. This mechanism is achieved by exploiting a multi-task learning framework that aims to explicitly guide the boundaries to their original locations. With one shared encoder, our network outputs (i) boundary localization, (ii) prediction of directions pointing to the object's interior, and (iii) semantic segmentation, in three parallel streams. The predicted boundaries and directions are fused to propagate the learned features to refine the segmentation. We conduct extensive experiments on the S3DIS and SensatUrban datasets against various baseline methods, demonstrating that our proposed approach yields consistent improvements by reducing boundary errors. Our code is available at https://github.com/shenglandu/PushBoundary.

Machine Learning (ML) interatomic models and potentials have been widely employed in simulations of materials. Long-range interactions often dominate in some ionic systems whose dynamics behavior is significantly influenced. However, the long-range effect such as Coulomb and Van der Wales potential is not considered in most ML interatomic potentials. To address this issue, we put forward a method that can take long-range effects into account for most ML local interatomic models with the reciprocal space neural network. The structure information in real space is firstly transformed into reciprocal space and then encoded into a reciprocal space potential or a global descriptor with full atomic interactions. The reciprocal space potential and descriptor keep full invariance of Euclidean symmetry and choice of the cell. Benefiting from the reciprocal-space information, ML interatomic models can be extended to describe the long-range potential including not only Coulomb but any other long-range interaction. A model NaCl system considering Coulomb interaction and the GaxNy system with defects are applied to illustrate the advantage of our approach. At the same time, our approach helps to improve the prediction accuracy of some global properties such as the band gap where the full atomic interaction beyond local atomic environments plays a very important role. In summary, our work has expanded the ability of current ML interatomic models and potentials when dealing with the long-range effect, hence paving a new way for accurate prediction of global properties and large-scale dynamic simulations of systems with defects.

Vision-language foundation models pretrained on large-scale data provide a powerful tool for many visual understanding tasks. Notably, many vision-language models build two encoders (visual and textual) that can map two modalities into the same embedding space. As a result, the learned representations achieve good zero-shot performance on tasks like image classification. However, when there are only a few examples per category, the potential of large vision-language models is often underperformed, mainly due to the gap between a large number of parameters and a relatively small amount of training data. This paper shows that we can significantly improve the performance of few-shot classification by using the category names to initialize the classification head. More interestingly, we can borrow the non-perfect category names, or even names from a foreign language, to improve the few-shot classification performance compared with random initialization. With the proposed category name initialization method, our model obtains the state-of-the-art performance on a number of few-shot image classification benchmarks (e.g., 87.37\% on ImageNet and 96.08\% on Stanford Cars, both using five-shot learning). We also investigate and analyze when the benefit of category names diminishes and how to use distillation to improve the performance of smaller models, providing guidance for future research.

捕获不规则点云的局部和全局特征对于3D对象检测（3OD）至关重要。但是，主流3D探测器，例如，投票机及其变体，要么放弃池操作过程中的大量本地功能，要么忽略整个场景中的许多全球功能。本文探讨了新的模块，以同时学习积极服务3OD的场景点云的局部全球特征。为此，我们通过同时局部全球特征学习（称为3DLG-detector）提出了一个有效的3OD网络。 3DLG检测器有两个关键贡献。首先，它会开发一个动态点交互（DPI）模块，该模块可在合并过程中保留有效的本地特征。此外，DPI是可拆卸的，可以将其合并到现有的3OD网络中以提高其性能。其次，它开发了一个全局上下文聚合模块，以汇总编码器不同层的多尺度特征，以实现场景上下文意识。我们的方法在SUN RGB-D和扫描仪数据集的检测准确性和鲁棒性方面显示了13个竞争对手的进步。源代码将在出版物时提供。
