本文解决了高光谱（HS）图像denoising的具有挑战性的问题。与现有的基于深度学习的方法不同，通常采用复杂的网络体系结构或经验堆叠现成的模块以提高性能，我们专注于捕获HS图像的高维特性的高效提取方式。具体来说，基于理论分析，提高由展开的卷积内核形成的矩阵的排名可以促进特征多样性，我们建议分别执行1卷卷积的降级低维卷积集（Re-Convset）沿着HS图像并排的三个维度，然后通过可学习的压缩层汇总所得的空间光谱嵌入。重新汇率不仅了解HS图像的不同空间光谱特征，而且还降低了网络的参数和复杂性。然后，我们将重新汇合纳入广泛使用的U-NET体系结构中，以构建HS图像Denoisising方法。令人惊讶的是，在定量指标，视觉结果和效率方面，我们观察到这样的简洁框架在很大程度上优于最新方法。我们相信我们的工作可能会阐明基于深度学习的HS图像处理和分析。

由遮挡，信号丢失或手动注释错误引起的3D边界框的地面真相注释的固有歧义可能会使训练过程中的深3D对象检测器混淆，从而使检测准确性恶化。但是，现有方法在某种程度上忽略了此类问题，并将标签视为确定性。在本文中，我们提出了GLENET，这是一个从条件变异自动编码器改编的生成标签不确定性估计框架，以建模典型的3D对象与其潜在的潜在基边界框之间具有潜在变量的一对一关系。 Glenet产生的标签不确定性是一个插件模块，可以方便地集成到现有的深3D检测器中，以构建概率检测器并监督本地化不确定性的学习。此外，我们提出了概率探测器中的不确定性质量估计量架构，以指导对IOU分支的培训，并预测了本地化不确定性。我们将提出的方法纳入各种流行的3D检测器中，并观察到它们的性能显着提高到Waymo Open DataSet和Kitti数据集中的当前最新技术。

顺序建议要求推荐人从已记录的用户行为数据中捕获不断发展的行为特征，以进行准确的建议。但是，用户行为序列被视为具有多个正在进行的线程交织在一起的脚本。我们发现，只有一小部分关键行为才能发展为用户的未来动作。结果，用户的未来行为很难预测。我们将每个用户作为行为途径的顺序行为的特征得出结论。不同的用户具有独特的行为途径。在现有的顺序模型中，变压器在捕获全球依赖性特征方面表现出很大的能力。但是，这些模型主要使用自我注意力的机制在所有先前的行为上提供了密集的分布，这使得最终预测被未调整给每个用户的微不足道行为所淹没。在本文中，我们使用新颖的途径注意机制构建了推荐变压器（RETR）。 REOR可以动态地计划为每个用户指定的行为途径，并通过此行为途径很少激活网络，以有效捕获对推荐有用的演变模式。关键设计是一种博学的二进制途径，以防止行为途径被微不足道的行为淹没。我们从经验上验证了RERO在七个现实世界数据集中的有效性，并产生了最先进的性能。

在本文中，我们通过深度学习研究了高光谱（HS）图像空间超分辨率的问题。特别是，我们专注于如何有效有效地嵌入HS图像的高维空间光谱信息。具体而言，与采用经验设计的网络模块的现有方法相反，我们将HS嵌入为一组精心定义的HS嵌入事件的后验分布的近似聚合。然后，我们将所提出的特征嵌入方案纳入源符合的超级分辨率框架中，该框架具有物理性开采，从而产生了轻质的PDE-NET，其中高分辨率（HR）HS图像是从输入低 - 低 - 之间的残差迭代完善的。分辨率（LR）HS图像和伪LR-HS图像通过概率启发的HS嵌入从重建的HR-HS图像中退化。在三个常见基准数据集上进行的广泛实验表明，PDE-NET比最先进的方法实现了卓越的性能。此外，这种网络的概率特征可以提供网络输出的认知不确定性，当用于其他基于HS图像的应用程序时，这可能会带来其他好处。该代码将在https://github.com/jinnh/pde-net上公开获得。

通过对齐跨模型自动化器的潜在空间来学习共同的潜在嵌入是广义零拍分类（GZSC）的有效策略。然而，由于缺乏细粒度的实例 - 明智的注释，它仍然很容易遭受域移位问题，用于多样化图像的视觉表示与固定属性的语义表示之间的差异。在本文中，我们通过学习对齐的跨模型表示（称为ACMR）来提出创新的AutoEncoder网络，用于GZSC。具体地，我们提出了一种新的视觉 - 语义对准（VSA）方法，以加强由学习分类器引导的潜在子空间上的交叉模态潜在特征的对准。此外，我们提出了一种新颖的信息增强模块（IEM），以减少潜在变量折叠的可能性同时鼓励潜在变量的判别能力。公开数据集的广泛实验证明了我们方法的最先进的性能。

Making safe and human-like decisions is an essential capability of autonomous driving systems and learning-based behavior planning is a promising pathway toward this objective. Distinguished from existing learning-based methods that directly output decisions, this work introduces a predictive behavior planning framework that learns to predict and evaluate from human driving data. Concretely, a behavior generation module first produces a diverse set of candidate behaviors in the form of trajectory proposals. Then the proposed conditional motion prediction network is employed to forecast other agents' future trajectories conditioned on each trajectory proposal. Given the candidate plans and associated prediction results, we learn a scoring module to evaluate the plans using maximum entropy inverse reinforcement learning (IRL). We conduct comprehensive experiments to validate the proposed framework on a large-scale real-world urban driving dataset. The results reveal that the conditional prediction model is able to forecast multiple possible future trajectories given a candidate behavior and the prediction results are reactive to different plans. Moreover, the IRL-based scoring module can properly evaluate the trajectory proposals and select close-to-human ones. The proposed framework outperforms other baseline methods in terms of similarity to human driving trajectories. Moreover, we find that the conditional prediction model can improve both prediction and planning performance compared to the non-conditional model, and learning the scoring module is critical to correctly evaluating the candidate plans to align with human drivers.

The security of artificial intelligence (AI) is an important research area towards safe, reliable, and trustworthy AI systems. To accelerate the research on AI security, the Artificial Intelligence Security Competition (AISC) was organized by the Zhongguancun Laboratory, China Industrial Control Systems Cyber Emergency Response Team, Institute for Artificial Intelligence, Tsinghua University, and RealAI as part of the Zhongguancun International Frontier Technology Innovation Competition (https://www.zgc-aisc.com/en). The competition consists of three tracks, including Deepfake Security Competition, Autonomous Driving Security Competition, and Face Recognition Security Competition. This report will introduce the competition rules of these three tracks and the solutions of top-ranking teams in each track.

The foundation models have recently shown excellent performance on a variety of downstream tasks in computer vision. However, most existing vision foundation models simply focus on image-level pretraining and adpation, which are limited for dynamic and complex video-level understanding tasks. To fill the gap, we present general video foundation models, InternVideo, by taking advantage of both generative and discriminative self-supervised video learning. Specifically, InternVideo efficiently explores masked video modeling and video-language contrastive learning as the pretraining objectives, and selectively coordinates video representations of these two complementary frameworks in a learnable manner to boost various video applications. Without bells and whistles, InternVideo achieves state-of-the-art performance on 39 video datasets from extensive tasks including video action recognition/detection, video-language alignment, and open-world video applications. Especially, our methods can obtain 91.1% and 77.2% top-1 accuracy on the challenging Kinetics-400 and Something-Something V2 benchmarks, respectively. All of these results effectively show the generality of our InternVideo for video understanding. The code will be released at https://github.com/OpenGVLab/InternVideo .

Background and Purpose: Colorectal cancer is a common fatal malignancy, the fourth most common cancer in men, and the third most common cancer in women worldwide. Timely detection of cancer in its early stages is essential for treating the disease. Currently, there is a lack of datasets for histopathological image segmentation of rectal cancer, which often hampers the assessment accuracy when computer technology is used to aid in diagnosis. Methods: This present study provided a new publicly available Enteroscope Biopsy Histopathological Hematoxylin and Eosin Image Dataset for Image Segmentation Tasks (EBHI-Seg). To demonstrate the validity and extensiveness of EBHI-Seg, the experimental results for EBHI-Seg are evaluated using classical machine learning methods and deep learning methods. Results: The experimental results showed that deep learning methods had a better image segmentation performance when utilizing EBHI-Seg. The maximum accuracy of the Dice evaluation metric for the classical machine learning method is 0.948, while the Dice evaluation metric for the deep learning method is 0.965. Conclusion: This publicly available dataset contained 5,170 images of six types of tumor differentiation stages and the corresponding ground truth images. The dataset can provide researchers with new segmentation algorithms for medical diagnosis of colorectal cancer, which can be used in the clinical setting to help doctors and patients.

内存处理（PIM）是一种越来越多地研究的神经形态硬件，承诺能量和吞吐量改进以进行深度学习推断。 PIM利用大量平行，有效的模拟计算在内存内部，绕过传统数字硬件中数据移动的瓶颈。但是，需要额外的量化步骤（即PIM量化），通常由于硬件约束而导致的分辨率有限，才能将模拟计算结果转换为数字域。同时，由于不完善的类似物到数字界面，PIM量化中的非理想效应广泛存在，这进一步损害了推理的准确性。在本文中，我们提出了一种培训量化网络的方法，以合并PIM量化，这对所有PIM系统无处不在。具体而言，我们提出了PIM量化意识培训（PIM-QAT）算法，并通过分析训练动力学以促进训练收敛，从而在向后传播期间引入重新传播技术。我们还提出了两种技术，即批处理归一化（BN）校准和调整精度训练，以抑制实际PIM芯片中涉及的非理想线性和随机热噪声的不利影响。我们的方法在三个主流PIM分解方案上进行了验证，并在原型芯片上进行了物理上的验证。与直接在PIM系统上部署常规训练的量化模型相比，该模型没有考虑到此额外的量化步骤并因此失败，我们的方法提供了重大改进。它还可以在CIFAR10和CIFAR100数据集上使用各种网络深度来获得最受欢迎的网络拓扑结构，在CIFAR10和CIFAR100数据集上，在PIM系统上达到了可比的推理精度。
