Semi-supervised learning (SSL) has made significant strides in the field of remote sensing. Finding a large number of labeled datasets for SSL methods is uncommon, and manually labeling datasets is expensive and time-consuming. Furthermore, accurately identifying remote sensing satellite images is more complicated than it is for conventional images. Class-imbalanced datasets are another prevalent phenomenon, and models trained on these become biased towards the majority classes. This becomes a critical issue with an SSL model's subpar performance. We aim to address the issue of labeling unlabeled data and also solve the model bias problem due to imbalanced datasets while achieving better accuracy. To accomplish this, we create "artificial" labels and train a model to have reasonable accuracy. We iteratively redistribute the classes through resampling using a distribution alignment technique. We use a variety of class imbalanced satellite image datasets: EuroSAT, UCM, and WHU-RS19. On UCM balanced dataset, our method outperforms previous methods MSMatch and FixMatch by 1.21% and 0.6%, respectively. For imbalanced EuroSAT, our method outperforms MSMatch and FixMatch by 1.08% and 1%, respectively. Our approach significantly lessens the requirement for labeled data, consistently outperforms alternative approaches, and resolves the issue of model bias caused by class imbalance in datasets.

Using a Bayesian network to analyze the causal relationship between nodes is a hot spot. The existing network learning algorithms are mainly constraint-based and score-based network generation methods. The constraint-based method is mainly the application of conditional independence (CI) tests, but the inaccuracy of CI tests in the case of high dimensionality and small samples has always been a problem for the constraint-based method. The score-based method uses the scoring function and search strategy to find the optimal candidate network structure, but the search space increases too much with the increase of the number of nodes, and the learning efficiency is very low. This paper presents a new hybrid algorithm, MCME (multiple compound memory erasing). This method retains the advantages of the first two methods, solves the shortcomings of the above CI tests, and makes innovations in the scoring function in the direction discrimination stage. A large number of experiments show that MCME has better or similar performance than some existing algorithms.

This work focuses on 3D Radar imaging inverse problems. Current methods obtain undifferentiated results that suffer task-depended information retrieval loss and thus don't meet the task's specific demands well. For example, biased scattering energy may be acceptable for screen imaging but not for scattering diagnosis. To address this issue, we propose a new task-oriented imaging framework. The imaging principle is task-oriented through an analysis phase to obtain task's demands. The imaging model is multi-cognition regularized to embed and fulfill demands. The imaging method is designed to be general-ized, where couplings between cognitions are decoupled and solved individually with approximation and variable-splitting techniques. Tasks include scattering diagnosis, person screen imaging, and parcel screening imaging are given as examples. Experiments on data from two systems indicate that the pro-posed framework outperforms the current ones in task-depended information retrieval.

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.

开放域对话系统旨在以开放式的方式通过自然语言文本与人类互动。但是，广泛成功的神经网络可能对对话系统无法正常工作，因为它们倾向于产生通用响应。在这项工作中，我们提出了一个相等大小的艰难期望 - 最大化（EQHARD-EM）算法来训练多样化对话生成的多次模型。我们的算法以艰苦的方式将样品分配给解码器，并强加了等同的约束，以确保所有解码器都经过良好的训练。我们提供详细的理论分析以证明我们的方法是合理的。此外，对两个大规模开放域对话数据集进行了实验，验证了我们的eqhard-em算法是否会产生高质量的不同响应。

在因果推理和强盗文献中，基于观察数据的线性功能估算线性功能的问题是规范的。我们分析了首先估计治疗效果函数的广泛的两阶段程序，然后使用该数量来估计线性功能。我们证明了此类过程的均方误差上的非反应性上限：这些边界表明，为了获得非反应性最佳程序，应在特定加权$ l^2 $中最大程度地估算治疗效果的误差。 -规范。我们根据该加权规范的约束回归分析了两阶段的程序，并通过匹配非轴突局部局部最小值下限，在有限样品中建立了实例依赖性最优性。这些结果表明，除了取决于渐近效率方差之外，最佳的非质子风险除了取决于样本量支持的最富有函数类别的真实结果函数与其近似类别之间的加权规范距离。

无人驾驶飞机（UAV）通过低成本，大型覆盖，实时和高分辨率数据采集能力而广泛应用于检查，搜索和救援行动的目的。在这些过程中产生了大量航空视频，在这些过程中，正常事件通常占压倒性的比例。本地化和提取异常事件非常困难，这些事件包含手动从长视频流中的潜在有价值的信息。因此，我们致力于开发用于解决此问题的异常检测方法。在本文中，我们创建了一个新的数据集，名为Droneanomaly，用于空中视频中的异常检测。该数据集提供了37个培训视频序列和22个测试视频序列，这些视频序列来自7个不同的现实场景，其中包括各种异常事件。有87,488个彩色视频框架（训练51,635，测试35,853），每秒30帧的尺寸为640美元\ times 640美元。基于此数据集，我们评估现有方法并为此任务提供基准。此外，我们提出了一种新的基线模型，即变压器（ANDT）的异常检测，该模型将连续的视频帧视为一系列小管，它利用变压器编码器从序列中学习特征表示，并利用解码器来预测下一帧。我们的网络模型在训练阶段模型正常，并确定了具有不可预测的时间动力学的事件，作为测试阶段的异常。此外，为了全面评估我们提出的方法的性能，我们不仅使用无人机 - 异常数据集，而且使用另一个数据集。我们将使我们的数据集和代码公开可用。可以在https://youtu.be/ancczyryoby上获得演示视频。我们使数据集和代码公开可用。

由于其低成本和快速移动性，无人驾驶汽车（UAV）现在已广泛应用于数据获取。随着航空视频量的增加，对这些视频自动解析的需求正在激增。为了实现这一目标，当前的研究主要集中于在空间和时间维度沿着卷积的整体特征提取整体特征。但是，这些方法受到小时接收场的限制，无法充分捕获长期的时间依赖性，这对于描述复杂动力学很重要。在本文中，我们提出了一个新颖的深神经网络，称为futh-net，不仅为整体特征建模，而且还模拟了空中视频分类的时间关系。此外，在新型融合模块中，多尺度的时间关系可以完善整体特征，以产生更具歧视性的视频表示。更特别地，FUTH-NET采用了两条道路架构：（1）学习框架外观和短期时间变化的一般特征的整体代表途径，以及（2）捕获跨任意跨越任意时间关系的时间关系途径框架，提供长期的时间依赖性。之后，提出了一个新型的融合模块，以时空整合从这两种途径中学到的两个特征。我们的模型对两个航空视频分类数据集进行了评估，即ERA和无人机操作，并实现了最新结果。这表明了其在不同识别任务（事件分类和人类行动识别）之间的有效性和良好的概括能力。为了促进进一步的研究，我们在https://gitlab.lrz.de/ai4eo/reasoning/futh-net上发布该代码。

室外（OOD）检测是面向任务的对话框系统中的关键组件，旨在确定查询是否不在预定义的支持的意图集之外。事实证明，先前基于软磁性的检测算法对OOD样品被过度自信。在本文中，我们分析了过度自信的OOD来自由于训练和测试分布之间的不匹配而导致的分布不确定性，这使得该模型无法自信地做出预测，因此可能导致异常软磁得分。我们提出了一个贝叶斯OOD检测框架，以使用Monte-Carlo辍学来校准分布不确定性。我们的方法是灵活的，并且可以轻松地插入现有的基于软磁性的基线和增益33.33 \％OOD F1改进，而与MSP相比仅增加了0.41 \％的推理时间。进一步的分析表明，贝叶斯学习对OOD检测的有效性。

现有的远处监督的关系提取器通常依靠嘈杂的数据进行模型培训和评估，这可能导致垃圾堆放系统。为了减轻问题，我们研究了小型清洁数据集是否可以帮助提高远距离监督模型的质量。我们表明，除了对模型进行更具说服力的评估外，一个小的清洁数据集还可以帮助我们构建更强大的Denoising模型。具体而言，我们提出了一个基于影响函数的清洁实例选择的新标准。它收集了样本级别的证据，以识别良好实例（这比损失级别的证据更具信息性）。我们还提出了一种教师实习机制，以控制自举套件时中间结果的纯度。整个方法是模型不合时宜的，并且在denoising Real（NYT）和合成噪声数据集上都表现出强烈的性能。
