视频检索随着视觉模型的发展取得了巨大进展。但是，进一步改进这些模型需要其他标记的数据，这是一项巨大的手动努力。在本文中，我们提出了一个框架MKTVR，该框架利用了从多语言模型的知识转移来提高视频检索的性能。我们首先使用最先进的机器翻译模型来构建伪真实的多语言视频文本对。然后，我们使用这些数据来学习视频文本表示，其中英语和非英语文本查询在基于预审前的多语言模型的常见嵌入空间中表示。我们在四个英语视频检索数据集上评估了我们提出的方法，例如MSRVTT，MSVD，DIDEMO和CHARADES。实验结果表明，我们的方法在所有数据集上实现了最先进的结果，超过了先前的模型。最后，我们还在涵盖六种语言的多语言视频回程数据集上评估了我们的模型，并表明我们的模型在零拍设置中优于先前的多语言视频检索模型。

近年来，具有两个较高架构的视觉语言（VL）模型主导了视觉表示的学习。当前的VL模型要么使用轻型Uni-Modal编码器，并在交叉模式编码器中同时提取，对齐和融合这两种模态，或者将最后一层的Uni-Modal-Modal特征直接馈入顶部的交叉模式编码器，而忽略了语义深度单模式编码器中不同级别的信息。两种方法都可能限制视觉表示学习和限制模型性能。在本文中，我们介绍了多个桥梁层，该层在Uni-Modal编码器的顶层和跨模式编码器的每一层之间建立了连接。这可以在不同语义级别的视觉和文本表示之间进行全面的自下而上相互作用，从而导致更有效的跨模式对齐和融合。我们提出的桥梁可以预先训练，仅需$ 4 $ m的图像，可以在各种下游视觉语言任务上实现最先进的性能。在VQAV2 Test-STD集合中，Bridge-Tower的准确性为$ 78.73 \％$，与以前的最先进的仪表型号相同的the Art仪表均优于先前的最先进的仪表\％$ $，并且几乎没有其他参数，并且几乎没有其他参数和其他参数计算成本。值得注意的是，当进一步扩展模型时，桥梁可以达到81.15美元\％$的准确性，超过了在较大的数据集中预先训练的模型。代码可在https://github.com/microsoft/bridgetower上找到。

基于变压器的模型的突破不仅彻底改变了NLP字段，而且彻底改变了视觉和多模式系统。但是，尽管可视化和可解释性工具已用于NLP模型，但视觉和多模式变压器的内部机制在很大程度上仍然不透明。随着这些变压器的成功，了解它们的内部运作越来越重要，因为揭开这些黑色盒子将导致更有能力和值得信赖的模型。为了为这一任务做出贡献，我们提出了VL-Interpret，它提供了新颖的交互式可视化，以解释多模式变压器中的关注和隐藏表示。 VL解释是一种任务不可知论和集成的工具，（1）在视觉和语言组件的所有层中跟踪注意力头的各种统计数据，（2）通过易于阅读的热图和跨模式和模式的关注可视化。 （3）绘制视觉和语言令牌穿过变压器层时的隐藏表示。在本文中，我们通过分析KD-VLP（一种基于端到端的视觉视觉方式多模式变压器的模型）在视觉常识推理（VCR）和两个，两个，两个，两个，两个，两个，两个，两个，两个，两个，两个接线型VLP（VCR）的任务，两个，两个，两个，两个，两个，两个，两个，两个，两个，两个，两个vlp，两个vlp，两个vlp，两个vlp，两个，我们在本文中证明了VL解干的功能。视觉问题回答基准。此外，我们还提出了一些有关通过我们的工具学到的多模式变压器行为的有趣发现。

自我监督的视觉和语言预处理（VLP）旨在从大规模的图像文本数据中学习可转移的多模式表示形式，并在填充后在广泛的视觉范围内实现强大的表现。以前的主流VLP方法通常采用依靠外部对象检测器来编码多模式变压器框架中的图像的两步策略，该框架遭受了限制性对象概念空间，有限的图像上下文和效率低下的计算。在本文中，我们提出了一个对象感知的端到端VLP框架，该框架将来自CNN的图像网格特征直接馈送到变压器中，并共同学习多模式表示。更重要的是，我们建议执行对象知识蒸馏，以促进在不同语义级别的学习跨模式对齐。为了实现这一目标，我们通过将对象特征及其来自外部检测器的语义标签作为监督来设计两个新颖的借口任务：1。）对象引导的蒙版视觉建模任务的重点是在多模式变压器中强制执行对象感知的表示的学习； 2.）短语区域对准任务旨在通过利用语言空间中名词短语和对象标签之间的相似性来改善跨模式对齐。对各种视觉语言任务进行的广泛实验证明了我们提出的框架的功效，并且我们在现有的预科策略中实现了竞争性或优越的表现。

Deep learning techniques with neural networks have been used effectively in computational fluid dynamics (CFD) to obtain solutions to nonlinear differential equations. This paper presents a physics-informed neural network (PINN) approach to solve the Blasius function. This method eliminates the process of changing the non-linear differential equation to an initial value problem. Also, it tackles the convergence issue arising in the conventional series solution. It is seen that this method produces results that are at par with the numerical and conventional methods. The solution is extended to the negative axis to show that PINNs capture the singularity of the function at $\eta=-5.69$

Graph Neural Networks (GNNs) have been widely applied to different tasks such as bioinformatics, drug design, and social networks. However, recent studies have shown that GNNs are vulnerable to adversarial attacks which aim to mislead the node or subgraph classification prediction by adding subtle perturbations. Detecting these attacks is challenging due to the small magnitude of perturbation and the discrete nature of graph data. In this paper, we propose a general adversarial edge detection pipeline EDoG without requiring knowledge of the attack strategies based on graph generation. Specifically, we propose a novel graph generation approach combined with link prediction to detect suspicious adversarial edges. To effectively train the graph generative model, we sample several sub-graphs from the given graph data. We show that since the number of adversarial edges is usually low in practice, with low probability the sampled sub-graphs will contain adversarial edges based on the union bound. In addition, considering the strong attacks which perturb a large number of edges, we propose a set of novel features to perform outlier detection as the preprocessing for our detection. Extensive experimental results on three real-world graph datasets including a private transaction rule dataset from a major company and two types of synthetic graphs with controlled properties show that EDoG can achieve above 0.8 AUC against four state-of-the-art unseen attack strategies without requiring any knowledge about the attack type; and around 0.85 with knowledge of the attack type. EDoG significantly outperforms traditional malicious edge detection baselines. We also show that an adaptive attack with full knowledge of our detection pipeline is difficult to bypass it.

The primary obstacle to developing technologies for low-resource languages is the lack of representative, usable data. In this paper, we report the deployment of technology-driven data collection methods for creating a corpus of more than 60,000 translations from Hindi to Gondi, a low-resource vulnerable language spoken by around 2.3 million tribal people in south and central India. During this process, we help expand information access in Gondi across 2 different dimensions (a) The creation of linguistic resources that can be used by the community, such as a dictionary, children's stories, Gondi translations from multiple sources and an Interactive Voice Response (IVR) based mass awareness platform; (b) Enabling its use in the digital domain by developing a Hindi-Gondi machine translation model, which is compressed by nearly 4 times to enable it's edge deployment on low-resource edge devices and in areas of little to no internet connectivity. We also present preliminary evaluations of utilizing the developed machine translation model to provide assistance to volunteers who are involved in collecting more data for the target language. Through these interventions, we not only created a refined and evaluated corpus of 26,240 Hindi-Gondi translations that was used for building the translation model but also engaged nearly 850 community members who can help take Gondi onto the internet.

This work introduces the novel task of Source-free Multi-target Domain Adaptation and proposes adaptation framework comprising of \textbf{Co}nsistency with \textbf{N}uclear-Norm Maximization and \textbf{Mix}Up knowledge distillation (\textit{CoNMix}) as a solution to this problem. The main motive of this work is to solve for Single and Multi target Domain Adaptation (SMTDA) for the source-free paradigm, which enforces a constraint where the labeled source data is not available during target adaptation due to various privacy-related restrictions on data sharing. The source-free approach leverages target pseudo labels, which can be noisy, to improve the target adaptation. We introduce consistency between label preserving augmentations and utilize pseudo label refinement methods to reduce noisy pseudo labels. Further, we propose novel MixUp Knowledge Distillation (MKD) for better generalization on multiple target domains using various source-free STDA models. We also show that the Vision Transformer (VT) backbone gives better feature representation with improved domain transferability and class discriminability. Our proposed framework achieves the state-of-the-art (SOTA) results in various paradigms of source-free STDA and MTDA settings on popular domain adaptation datasets like Office-Home, Office-Caltech, and DomainNet.

神经网络在与噪声扰动的图像分类中的精度较小。 CNN卷积神经网络以其在良性图像的分类中无与伦比的精度而闻名。但是我们的研究表明，它们极易受到噪声的攻击，而馈送前向神经网络，FNN与噪声扰动的对应性较小，几乎不受干扰地保持其准确性。观察到FNN可以更好地分类噪声密集的单通道图像，而这些图像只是人类视觉的巨大噪音。在我们的研究中，我们使用了以下架构的手写数字数据集，MNIST：具有1和2个隐藏层和CNN的FNN，带有3、4、6和8卷积，并分析了其准确性。 FNN脱颖而出表明，无论噪声强度如何，它们的分类精度超过85％。在我们通过此数据对CNN的分析中，CNN的分类准确性减速8卷积是其余CNN的一半。准确性趋势的相关分析和数学建模是这些结论的路线图。

强化学习（RL）是一种机器学习范式，自主代理人通过与基础环境进行互动来学会做出最佳决策顺序。 RL引导的工作流在解开电子设计自动化问题中所证明的诺言鼓励硬件安全研究人员利用自动RL代理来解决特定领域的问题。从硬件安全性的角度来看，这种自主代理人可以在未知的对抗环境中产生最佳动作。另一方面，综合电路供应链的持续全球化迫使芯片制造成为离岸，不信任的实体，从而增加了对硬件安全性的担忧。此外，未知的对抗环境和增加的设计复杂性使后卫在检测攻击者（又称硬件木马）进行的微妙修改方面具有挑战性。在此简介中，我们概述了RL代理在检测硬件Trojans时的开发，这是最具挑战性的硬件安全问题之一。此外，我们概述了潜在的机会，并提出了应用RL解决硬件安全问题的挑战。
