包含丰富信息的元素图像和视频需要大量的数据存储和高传输成本。虽然对元素图像编码进行了很多研究，但对元素视频编码的研究非常有限。我们通过查看射线空间域中的问题而不是在常规像素域中的问题来研究元素视频编码的运动补偿。在这里，我们在射线空间运动的两个子轴上，即整数射线空间运动和分数射线空间运动，为Lenslet视频开发了一种新颖的运动补偿方案。拟议的新方案设计了光场运动补偿预测，使其可以轻松地集成到众所周知的视频编码技术中，例如HEVC。与现有方法相比，实验结果显示出显着的压缩效率，平均增益为19.63％，峰值增长率为29.1％。

Recognizing handwriting images is challenging due to the vast variation in writing style across many people and distinct linguistic aspects of writing languages. In Vietnamese, besides the modern Latin characters, there are accent and letter marks together with characters that draw confusion to state-of-the-art handwriting recognition methods. Moreover, as a low-resource language, there are not many datasets for researching handwriting recognition in Vietnamese, which makes handwriting recognition in this language have a barrier for researchers to approach. Recent works evaluated offline handwriting recognition methods in Vietnamese using images from an online handwriting dataset constructed by connecting pen stroke coordinates without further processing. This approach obviously can not measure the ability of recognition methods effectively, as it is trivial and may be lack of features that are essential in offline handwriting images. Therefore, in this paper, we propose the Transferring method to construct a handwriting image dataset that associates crucial natural attributes required for offline handwriting images. Using our method, we provide a first high-quality synthetic dataset which is complex and natural for efficiently evaluating handwriting recognition methods. In addition, we conduct experiments with various state-of-the-art methods to figure out the challenge to reach the solution for handwriting recognition in Vietnamese.

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License.

3D对象检测是自动驾驶的重要组成部分，深层神经网络（DNNS）已达到此任务的最新性能。但是，深层模型臭名昭著，因为将高置信度得分分配给分布（OOD）输入，即未从训练分布中得出的输入。检测OOD输入是具有挑战性的，对于模型的安全部署至关重要。已经针对分类任务进行了广泛研究OOD检测，但是它尚未对对象检测任务，特别是基于激光雷达的3D对象检测的注意力。在本文中，我们关注基于激光雷达的3D对象检测的OOD输入的检测。我们制定了OOD输入对于对象检测的含义，并提议适应几种OOD检测方法进行对象检测。我们通过提出的特征提取方法来实现这一目标。为了评估OOD检测方法，我们开发了一种简单但有效的技术，用于为给定的对象检测模型生成OOD对象​​。我们基于KITTI数据集的评估表明，不同的OOD检测方法具有检测特定OOD对象​​的偏差。它强调了联合OOD检测方法的重要性以及在这个方向上进行更多研究。

我们为神经机翻译（NMT）提供了一个开源工具包。新工具包主要基于拱形变压器（Vaswani等，2017）以及下面详述的许多其他改进，以便创建一个独立的，易于使用，一致和全面的各个领域的机器翻译任务框架。它是为了支持双语和多语言翻译任务的工具，从构建各个语料库的模型开始推断新的预测或将模型打包给提供功能的JIT格式。

知识图（kg）对齐 - 指识别不同kgs中同一件事的实体的任务 - 被认为是KG构造领域中最重要的操作之一。然而，现有的对齐技术通常假设输入kgs是完整的并且同性的，这是由于域，大小和稀疏性的现实世界异质性而不是真实。在这项工作中，我们解决了与代表学习对齐不完整的KG对齐的问题。我们的KG嵌入式框架利用了两个特征频道：基于传输型和基于接近的。前者通过翻译路径捕获实体之间的一致性约束，而后者通过注意引导关系感知图形神经网络捕获KG的邻域结构。两个特征频道共同学习以在输入kgs之间交换重要特征，同时强制在同一嵌入空间中强制输入kg的输出表示。此外，我们开发了缺失的链接检测器，该探测器发现并恢复培训过程中输入kgs中的缺失链接，这有助于减轻不完整性问题，从而提高学习象征的兼容性。然后将嵌入的熔合融合以生成对准结果，并且高置信匹配节点对被更新为预先调整的监控数据以逐渐改善嵌入。经验结果表明，我们的型号比SOTA更准确，而且对不同级别的不完整性较高，高达15.2 \％。我们还证明了KGS之间交换的知识有助于揭示知识图表（A.K.A.知识完成）的看不见的事实，结果比SOTA知识图形完成技术高3.5 \％。

近年来，视觉伪造达到了人类无法识别欺诈的复杂程度，这对信息安全构成了重大威胁。出现了广泛的恶意申请，例如名人的假新闻，诽谤或勒索，政治战中的政治家冒充，以及谣言的传播吸引观点。结果，已经提出了一种富有的视觉验证技术，以试图阻止这种危险的趋势。在本文中，我们使用全面的和经验方法，提供了一种基准，可以对视觉伪造和视觉取证进行深入的洞察。更具体地，我们开发一个独立的框架，整合最先进的假冒生成器和探测器，并使用各种标准来测量这些技术的性能。我们还对基准测试结果进行了详尽的分析，确定了在措施与对策之间永无止境的战争中的比较参考的方法的特征。

安全保证是自动驾驶（AD）系统发展和社会接受（AD）系统的核心问题。感知是广告的关键方面，严重依赖机器学习（ML）。尽管基于ML的组件的安全性有已知的挑战，但最近已经提出针对解决这些组件的单位安全案例的建议。不幸的是，AD安全案例在系统级别上表示安全要求，这些努力缺少将安全性要求与单位级别的组件性能要求整合在一起所需的关键链接参数。在本文中，我们提出了感知的集成安全案例（ISCAP），这是针对专门针对感知组件量身定制的这种链接安全参数的通用模板。该模板采用演绎且形式上的方法来定义级别之间强大的可追溯性。我们通过详细的案例研究证明了ISCAP的适用性，并讨论了其作为支持感知成分增量发展的工具的使用。

RTE is a significant problem and is a reasonably active research community. The proposed research works on the approach to this problem are pretty diverse with many different directions. For Vietnamese, the RTE problem is moderately new, but this problem plays a vital role in natural language understanding systems. Currently, methods to solve this problem based on contextual word representation learning models have given outstanding results. However, Vietnamese is a semantically rich language. Therefore, in this paper, we want to present an experiment combining semantic word representation through the SRL task with context representation of BERT relative models for the RTE problem. The experimental results give conclusions about the influence and role of semantic representation on Vietnamese in understanding natural language. The experimental results show that the semantic-aware contextual representation model has about 1% higher performance than the model that does not incorporate semantic representation. In addition, the effects on the data domain in Vietnamese are also higher than those in English. This result also shows the positive influence of SRL on RTE problem in Vietnamese.

We propose a new causal inference framework to learn causal effects from multiple, decentralized data sources in a federated setting. We introduce an adaptive transfer algorithm that learns the similarities among the data sources by utilizing Random Fourier Features to disentangle the loss function into multiple components, each of which is associated with a data source. The data sources may have different distributions; the causal effects are independently and systematically incorporated. The proposed method estimates the similarities among the sources through transfer coefficients, and hence requiring no prior information about the similarity measures. The heterogeneous causal effects can be estimated with no sharing of the raw training data among the sources, thus minimizing the risk of privacy leak. We also provide minimax lower bounds to assess the quality of the parameters learned from the disparate sources. The proposed method is empirically shown to outperform the baselines on decentralized data sources with dissimilar distributions.
