Research on remote sensing image classification significantly impacts essential human routine tasks such as urban planning and agriculture. Nowadays, the rapid advance in technology and the availability of many high-quality remote sensing images create a demand for reliable automation methods. The current paper proposes two novel deep learning-based architectures for image classification purposes, i.e., the Discriminant Deep Image Prior Network and the Discriminant Deep Image Prior Network+, which combine Deep Image Prior and Triplet Networks learning strategies. Experiments conducted over three well-known public remote sensing image datasets achieved state-of-the-art results, evidencing the effectiveness of using deep image priors for remote sensing image classification.

Identifying anomalies has become one of the primary strategies towards security and protection procedures in computer networks. In this context, machine learning-based methods emerge as an elegant solution to identify such scenarios and learn irrelevant information so that a reduction in the identification time and possible gain in accuracy can be obtained. This paper proposes a novel feature selection approach called Finite Element Machines for Feature Selection (FEMa-FS), which uses the framework of finite elements to identify the most relevant information from a given dataset. Although FEMa-FS can be applied to any application domain, it has been evaluated in the context of anomaly detection in computer networks. The outcomes over two datasets showed promising results.

In the last decade, exponential data growth supplied machine learning-based algorithms' capacity and enabled their usage in daily-life activities. Additionally, such an improvement is partially explained due to the advent of deep learning techniques, i.e., stacks of simple architectures that end up in more complex models. Although both factors produce outstanding results, they also pose drawbacks regarding the learning process as training complex models over large datasets are expensive and time-consuming. Such a problem is even more evident when dealing with video analysis. Some works have considered transfer learning or domain adaptation, i.e., approaches that map the knowledge from one domain to another, to ease the training burden, yet most of them operate over individual or small blocks of frames. This paper proposes a novel approach to map the knowledge from action recognition to event recognition using an energy-based model, denoted as Spectral Deep Belief Network. Such a model can process all frames simultaneously, carrying spatial and temporal information through the learning process. The experimental results conducted over two public video dataset, the HMDB-51 and the UCF-101, depict the effectiveness of the proposed model and its reduced computational burden when compared to traditional energy-based models, such as Restricted Boltzmann Machines and Deep Belief Networks.

复杂的伤口通常会面临部分或完全损失皮肤厚度,从而通过次要意图愈合。它们可以是急性或慢性的,可以发现感染,缺血和组织坏死以及与全身性疾病的关联。全球研究机构报告了无数案件,最终涉及严重的公共卫生问题,因为它们涉及人力资源(例如医师和医疗保健专业人员),并对生活质量产生负面影响。本文提出了一个新的数据库,用于自动将复杂伤口自动分类为五个类别,即非缠绕区域,肉芽,纤维蛋白样组织和干性坏死,血肿。这些图像包括由压力,血管溃疡,糖尿病,燃烧和手术干预后的并发症引起的复杂伤口的不同情况。该数据集(称为ComplexWoundDB)是独一无二的,因为它可以从野外获得的27美元图像中的像素级分类,即在患者的房屋中收集图像,并由四名卫生专业人员标记。用不同的机器学习技术进行的进一步实验证明了解决计算机辅助复杂伤口组织分类问题的挑战。手稿阐明了该地区未来的方向,在文献中广泛使用的其他数据库中进行了详细比较。

需要在机器学习模型中对最小参数设置的需求,以避免耗时的优化过程。$ k $ - 最终的邻居是在许多问题中使用的最有效,最直接的模型之一。尽管具有众所周知的性能,但它仍需要特定数据分布的$ K $值,从而需要昂贵的计算工作。本文提出了一个$ k $ - 最终的邻居分类器,该分类器绕过定义$ k $的值的需求。考虑到训练集的数据分布,该模型计算$ k $值。我们将提出的模型与标准$ K $ - 最近的邻居分类器和文献中的两个无参数版本进行了比较。11个公共数据集的实验证实了所提出方法的鲁棒性,因为所获得的结果相似甚至更好。

本文提出了Mburst,这是一种新型的多模式解决方案,用于视听语音增强功能,该解决方案考虑了有关前额叶皮层和其他大脑区域的锥体细胞的最新神经系统发现。所谓的爆发传播实现了几个标准,以更加可行的方式解决信用分配问题:通过反馈来指导可塑性的标志和大小,并线性化反馈信号。 Mburst从这种能力中受益于学习嘈杂信号和视觉刺激之间的相关性,从而通过扩增相关信息和抑制噪声来归因于语音。通过网格语料库和基于Chime3的数据集进行的实验表明,Mburst可以将类似的掩模重建基于多模态反向传播基线,同时证明了出色的能量效率管理,从而降低了神经元的发射速率,以降低价值,最高为\ textbf {$ 70 \%$}降低。这样的功能意味着更可持续的实现,适合助听器或任何其他类似的嵌入式系统。

当大量机器人试图到达公共区域时,会发生拥堵,导致严重的延误。为了最大程度地减少机器人群体中的交通拥堵,必须以分散的方式使用交通控制算法。基于旨在最大化共同目标区域吞吐量的策略,我们使用人工潜在领域为机器人开发了两种新颖的算法,以避免障碍和导航。一种算法是通过创建一个队列到达目标区域的启发的(单队列以前-SQF),而另一个使机器人通过使用矢量字段(触摸和运行矢量字段-TRVF)使机器人触摸圆形区域的边界。 。我们进行了仿真实验,以表明所提出的算法受其启发的理论策略的吞吐量,并将两种新型算法与同一问题的最先进算法进行比较(PCC,EE和PCC-EE)。 SQF算法明显优于大量机器人或圆形目标区域半径较小的所有其他算法。另一方面,对于有限数量的机器人,TRVF仅比SQF更好,而对于众多机器人来说,TRVF仅优于PCC。但是,它使我们能够分析当思想从理论策略转移到混凝土算法时对吞吐量的潜在影响,该算法考虑了改变机器人之间的线性速度和距离。

通常,基于生物谱系的控制系统可能不依赖于各个预期行为或合作适当运行。相反,这种系统应该了解未经授权的访问尝试的恶意程序。文献中提供的一些作品建议通过步态识别方法来解决问题。这些方法旨在通过内在的可察觉功能来识别人类,尽管穿着衣服或配件。虽然该问题表示相对长时间的挑战,但是为处理问题的大多数技术存在与特征提取和低分类率相关的几个缺点,以及其他问题。然而,最近的深度学习方法是一种强大的一组工具,可以处理几乎任何图像和计算机视觉相关问题,为步态识别提供最重要的结果。因此,这项工作提供了通过步态认可的关于生物识别检测的最近作品的调查汇编,重点是深入学习方法,强调他们的益处,暴露出弱点。此外,它还呈现用于解决相关约束的数据集,方法和体系结构的分类和表征描述。

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.

在多语言甚至单语言中鉴定的模型的零拍跨语言能力刺激了许多假设,以解释这一有趣的经验结果。但是,由于预处理的成本,大多数研究都使用公共模型的公共模型,其预处理方法(例如代币化,语料库规模和计算预算的选择)可能会大不相同。当研究人员对自己的模型预识时,他们通常会在预算有限的情况下这样做,并且与SOTA模型相比,最终的模型的表现可能明显不足。这些实验差异导致有关这些模型跨语性能力的性质的各种不一致的结论。为了帮助对该主题进行进一步研究,我们发布了10个单语字节级模型,并在相同的配置下进行了严格审慎的概述,并具有大型计算预算(相当于V100的420天)和Corpora,比原始BERT大4倍。由于它们不含令牌,因此消除了看不见的令牌嵌入的问题,从而使研究人员可以在具有不同脚本的语言中尝试更广泛的跨语言实验。此外,我们释放了在不自然语言文本上预测的两个模型,这些模型可用于理智检查实验。关于质量检查和NLI任务的实验表明,我们的单语模型实现了多语言的竞争性能,因此可以加强我们对语言模型中跨语性可传递性的理解。
