远远超出了学习自然语言的远程相互作用，变形金刚正成为许多愿景任务的遗弃标准，具有其力量和爬钢丝。特别是在图像和文本之间的跨模型任务中，向量量化变化自动码器（VQ-VAE）被广泛用于使原始RGB图像成为一系列特征向量。为了更好地利用图像和文本之间的相关性，我们提出了一种新颖的架构，该架构包括用于文本到图像和图像到文本的特征增强的变形Autiachoder（Augvae）和双向自动回归变压器（Biart）一代。我们的Augvae在ImageNet1K验证集上显示了最先进的重建性能，以及野外未经看出图像的鲁棒性。与其他模型不同，BIART可以将图像（或文本）区分为条件参考和生成目标。 L-VERSE可以直接用于图像到文本或文本到图像生成任务，而无需任何FineTuning或额外的对象检测框架。在定量和定性实验中，L-VESERS在MS-Coco字幕上的图像到文本和文本到图像生成中，对先前的方法进行了令人印象深刻的结果。我们还评估了L-Verse架构对概念标题的可扩展性，并呈现了一般域的双向视觉语言表示学习的初始结果。代码可用：https://github.com/tgisaturday/l-verse

该报告解释，实施和扩展了“更紧密的变化界限不一定更好”所介绍的作品（T Rainforth等，2018）。我们提供了理论和经验证据，这些证据增加了重要性的重要性数量$ k $在重要性加权自动编码器（IWAE）中（Burda等，2016）降低了推理中梯度估计量的信噪比（SNR）网络，从而影响完整的学习过程。换句话说，即使增加$ k $减少了梯度的标准偏差，但它也会更快地降低真实梯度的幅度，从而增加梯度更新的相对差异。进行广泛的实验以了解$ k $的重要性。这些实验表明，更紧密的变化界限对生成网络有益，而宽松的边界对推理网络来说是可取的。通过这些见解，可以实施和研究三种方法：部分重要性加权自动编码器（PIWAE），倍增重要性加权自动编码器（MIWAE）和组合重要性加权自动编码器（CIWAE）。这三种方法中的每一种都需要IWAE作为一种特殊情况，但采用不同的重量权重，以确保较高的梯度估计器的SNR。在我们的研究和分析中，这些算法的疗效在多个数据集（如MNIST和Omniglot）上进行了测试。最后，我们证明了三种呈现的IWAE变化能够产生近似后验分布，这些分布与IWAE更接近真正的后验分布，同时匹配IWAE生成网络的性能，或者在PIWAE的情况下可能超过其表现。

近年来，深度学习导致了在城市驾驶场景中移动（即具有运动能力）物体的检测方面取得的巨大进展。监督方法通常需要大型培训集的注释；因此，人们对利用弱，半或自我监督的方法避免这种情况非常兴趣，并取得了很大的成功。虽然弱和半监督的方法需要一些注释，但自我监督的方法已经使用了诸如运动之类的线索来完全减轻注释的需求。但是，完全没有注释通常会降低其性能，而在运动组进行分组期间出现的歧义可以抑制其找到准确的物体边界的能力。在本文中，我们提出了一种称为SCT的新的自制移动对象检测方法。这同时使用运动提示和预期对象大小来提高检测性能，并预测3D方向边界框的密集网格以改善对象发现。我们在Kitti跟踪基准上的最先进的自我监督的移动对象检测方法TCR极大地超过了，并且实现了全面监督的PV-RCNN ++方法的30％以内IOUS <= 0.5。

基于图像的虚拟试验旨在综合一个穿给定服装的人的图像。为了解决任务，现有的方法会经过衣物项目，以适合该人的身体并生成穿着该物品的人的分割图，然后再将物品与人融合。但是，当扭曲和分割生成阶段在没有信息交换的情况下单独运行时，扭曲的衣服和分割图之间的未对准发生了，从而导致最终图像中的工件。信息断开还会导致在身体部位遮住的衣服区域附近过度翘曲，所谓的像素 - 刺式伪像。为了解决这些问题，我们提出了一个新颖的尝试条件发生器，作为两个阶段的统一模块（即扭曲和分割生成阶段）。条件生成器中新提出的特征融合块实现了信息交换，并且条件生成器不会造成任何未对准或像素 - 平方形工件。我们还介绍了歧视者的拒绝，从而滤除了不正确的细分图预测并确保虚拟试验框架的性能。高分辨率数据集上的实验表明，我们的模型成功处理了未对准和遮挡，并显着优于基线。代码可从https://github.com/sangyun884/hr-viton获得。

共同监督的深度学习方法的关节深度和自我运动估计可以产生准确的轨迹，而无需地面真相训练数据。但是，由于通常会使用光度损失，因此当这些损失所产生的假设（例如时间照明一致性，静态场景以及缺少噪声和遮挡）时，它们的性能会显着降解。这限制了它们用于例如夜间序列倾向于包含许多点光源（包括在动态对象上）和较暗图像区域中的低信噪比（SNR）。在本文中，我们展示了如何使用三种技术的组合来允许现有的光度损失在白天和夜间图像中起作用。首先，我们引入了每个像素神经强度转化，以补偿连续帧之间发生的光变化。其次，我们预测了每个像素的残差流图，我们用来纠正由网络估计的自我运动和深度引起的重新注入对应关系。第三，我们将训练图像降低，以提高方法的鲁棒性和准确性。这些更改使我们可以在白天和夜间图像中训练单个模型，而无需单独的编码器或诸如现有方法（例如现有方法）的额外功能网络。我们对具有挑战性的牛津机器人数据集进行了广泛的实验和消融研究，以证明我们方法对白天和夜间序列的疗效。

无监督的现实世界超级分辨率（USR）旨在恢复给定低分辨率（LR）输入的高分辨率（HR）图像，并且其难度源于缺乏配对数据集。最常见的方法之一是使用gan（即降解发生器）合成嘈杂的LR图像，并利用合成数据集以监督的方式训练模型。尽管训练降解发生器的目的是近似于给定HR图像的LR图像的分布，但以前的作品严重依赖于条件分布是Delta功能的不现实假设，并了解了从HR图像到LR的确定性映射图片。在本文中，我们表明我们可以通过放松假设并提议训练概率降解发生器来提高USR模型的性能。我们的概率降解发生器可以视为深层层次潜在变量模型，并且更适合对复杂的条件分布进行建模。我们还揭示了与stylegan噪声注入的显着联系。此外，我们培训多个退化发生器以改善模式覆盖范围并应用协作学习以易于培训。根据PSNR和SSIM，我们在基准数据集上的表现优于几个基准，并证明了我们在看不见的数据分布方面的鲁棒性。代码可在https://github.com/sangyun884/mssr上找到。

The 3D-aware image synthesis focuses on conserving spatial consistency besides generating high-resolution images with fine details. Recently, Neural Radiance Field (NeRF) has been introduced for synthesizing novel views with low computational cost and superior performance. While several works investigate a generative NeRF and show remarkable achievement, they cannot handle conditional and continuous feature manipulation in the generation procedure. In this work, we introduce a novel model, called Class-Continuous Conditional Generative NeRF ($\text{C}^{3}$G-NeRF), which can synthesize conditionally manipulated photorealistic 3D-consistent images by projecting conditional features to the generator and the discriminator. The proposed $\text{C}^{3}$G-NeRF is evaluated with three image datasets, AFHQ, CelebA, and Cars. As a result, our model shows strong 3D-consistency with fine details and smooth interpolation in conditional feature manipulation. For instance, $\text{C}^{3}$G-NeRF exhibits a Fr\'echet Inception Distance (FID) of 7.64 in 3D-aware face image synthesis with a $\text{128}^{2}$ resolution. Additionally, we provide FIDs of generated 3D-aware images of each class of the datasets as it is possible to synthesize class-conditional images with $\text{C}^{3}$G-NeRF.

In both terrestrial and marine ecology, physical tagging is a frequently used method to study population dynamics and behavior. However, such tagging techniques are increasingly being replaced by individual re-identification using image analysis. This paper introduces a contrastive learning-based model for identifying individuals. The model uses the first parts of the Inception v3 network, supported by a projection head, and we use contrastive learning to find similar or dissimilar image pairs from a collection of uniform photographs. We apply this technique for corkwing wrasse, Symphodus melops, an ecologically and commercially important fish species. Photos are taken during repeated catches of the same individuals from a wild population, where the intervals between individual sightings might range from a few days to several years. Our model achieves a one-shot accuracy of 0.35, a 5-shot accuracy of 0.56, and a 100-shot accuracy of 0.88, on our dataset.

Feature selection helps reduce data acquisition costs in ML, but the standard approach is to train models with static feature subsets. Here, we consider the dynamic feature selection (DFS) problem where a model sequentially queries features based on the presently available information. DFS is often addressed with reinforcement learning (RL), but we explore a simpler approach of greedily selecting features based on their conditional mutual information. This method is theoretically appealing but requires oracle access to the data distribution, so we develop a learning approach based on amortized optimization. The proposed method is shown to recover the greedy policy when trained to optimality and outperforms numerous existing feature selection methods in our experiments, thus validating it as a simple but powerful approach for this problem.

The purpose of this work was to tackle practical issues which arise when using a tendon-driven robotic manipulator with a long, passive, flexible proximal section in medical applications. A separable robot which overcomes difficulties in actuation and sterilization is introduced, in which the body containing the electronics is reusable and the remainder is disposable. A control input which resolves the redundancy in the kinematics and a physical interpretation of this redundancy are provided. The effect of a static change in the proximal section angle on bending angle error was explored under four testing conditions for a sinusoidal input. Bending angle error increased for increasing proximal section angle for all testing conditions with an average error reduction of 41.48% for retension, 4.28% for hysteresis, and 52.35% for re-tension + hysteresis compensation relative to the baseline case. Two major sources of error in tracking the bending angle were identified: time delay from hysteresis and DC offset from the proximal section angle. Examination of these error sources revealed that the simple hysteresis compensation was most effective for removing time delay and re-tension compensation for removing DC offset, which was the primary source of increasing error. The re-tension compensation was also tested for dynamic changes in the proximal section and reduced error in the final configuration of the tip by 89.14% relative to the baseline case.
