测试时间适应（TTA）是一个新兴范式，可解决培训和测试阶段之间的分布变化，而无需其他数据采集或标签成本；仅使用未标记的测试数据流进行连续模型适应。以前的TTA方案假设测试样本是独立的，并且分布相同（i.i.d.），即使它们在应用程序方案中通常在时间上相关（non-i.i.d。），例如自动驾驶。我们发现，在这种情况下，大多数现有的TTA方法急剧失败。由此激励，我们提出了一种新的测试时间适应方案，该方案对非I.I.D具有强大的态度。测试数据流。我们的新颖性主要是两倍：（a）纠正分布样本的归一化的实例感知批归归量表（IABN），以及（b）模拟I.I.D.的预测均衡储层采样（PBRS）。来自非i.i.d的数据流。以班级平衡的方式流式传输。我们对各种数据集的评估，包括现实世界非i.i.d。流，表明所提出的强大TTA不仅优于非i.i.d的最先进的TTA算法。设置，但也可以实现与I.I.D.下的这些算法相当的性能。假设。

学习公平的代表性对于实现公平或宣传敏感信息至关重要。大多数现有的作品都依靠对抗表示学习将一些不变性注入表示形式。但是，已知对抗性学习方法受到相对不稳定的训练的痛苦，这可能会损害公平性和代表性预测之间的平衡。我们提出了一种新的方法，通过分布对比度变异自动编码器（Farconvae）学习公平表示，该方法诱导潜在空间分解为敏感和非敏感部分。我们首先构建具有不同敏感属性但具有相同标签的观测值。然后，Farconvae强制执行每个不敏感的潜在潜在，而敏感的潜在潜在的潜伏期彼此之间的距离也很远，并且还远离非敏感的潜在通过对比它们的分布。我们提供了一种由高斯和Student-T内核动机的新型对比损失，用于通过理论分析进行分配对比学习。此外，我们采用新的掉期重建损失，进一步提高分解。 Farconvae在公平性，预处理的模型偏差以及来自各种模式（包括表格，图像和文本）的领域概括任务方面表现出了卓越的性能。

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

许多利用移动设备中的传感器的应用以及应用机器学习以提供新颖的服务。然而，诸如不同的用户，设备，环境和超参数之类的各种因素影响了这种应用的性能，从而使域移位（即，来自训练源数据集的目标用户的分发偏移）是一个重要问题。虽然最近的域适应技术试图解决这个问题，但各种因素之间的复杂相互作用通常会限制其有效性。我们认为，准确估算未训练的域中的性能可能会显着降低性能不确定性。我们呈现Dapper（域适配性能估计器），其估计目标域中的适应性能，只有未标记的目标数据。我们的直觉是目标数据上模型的输出提供了模型在目标域中的实际性能的线索。 Dapper不需要昂贵的标签成本，也不需要在部署后涉及额外的培训。与四个基线相比，我们与四个真实世界传感数据集进行了评估，表明，估计精度平均17％平均占据了基线的表现。此外，我们的On-Device实验表明，与基线相比，Dapper达到了多达216倍的计算开销。

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.

According to the rapid development of drone technologies, drones are widely used in many applications including military domains. In this paper, a novel situation-aware DRL- based autonomous nonlinear drone mobility control algorithm in cyber-physical loitering munition applications. On the battlefield, the design of DRL-based autonomous control algorithm is not straightforward because real-world data gathering is generally not available. Therefore, the approach in this paper is that cyber-physical virtual environment is constructed with Unity environment. Based on the virtual cyber-physical battlefield scenarios, a DRL-based automated nonlinear drone mobility control algorithm can be designed, evaluated, and visualized. Moreover, many obstacles exist which is harmful for linear trajectory control in real-world battlefield scenarios. Thus, our proposed autonomous nonlinear drone mobility control algorithm utilizes situation-aware components those are implemented with a Raycast function in Unity virtual scenarios. Based on the gathered situation-aware information, the drone can autonomously and nonlinearly adjust its trajectory during flight. Therefore, this approach is obviously beneficial for avoiding obstacles in obstacle-deployed battlefields. Our visualization-based performance evaluation shows that the proposed algorithm is superior from the other linear mobility control algorithms.
