基于微服务的体系结构已成为云原生应用程序的普遍存在。每天利用越来越多的应用程序在云平台上部署的应用程序，需要进行更多的研究工作，以了解如何应用不同的策略来有效地管理各种云资源。大量研究已使用反应性和主动自动化策略部署了自动资源分配算法。但是，当前算法的效率仍然存在差距，例如从其体系结构和部署环境中捕获微服务的重要特征，例如，缺乏对图形依赖性的考虑。为了应对这一挑战，我们提出了Graph-PHPA，这是一种基于图的主动水平POD自动级别自动化策略，用于将云资源分配给微服务，以利用长期短期记忆（LSTM）和基于图形神经网络（GNN）的预测方法。我们使用BookInfo微服务在专用的测试环境中使用基于现实数据集生成的实时工作负载来评估图形phpa的性能。我们通过将图形PHPA与Kubernetes中基于规则的资源分配方案进行比较来证明了图形phpa的疗效。已经实施了广泛的实验，我们的结果说明了我们在不同测试方案中提出的资源节省方法优于基于反应性规则的基线算法的优势。

State-of-the-art machine translation evaluation metrics are based on black-box language models. Hence, recent works consider their explainability with the goals of better understandability for humans and better metric analysis, including failure cases. In contrast, we explicitly leverage explanations to boost the metrics' performance. In particular, we perceive explanations as word-level scores, which we convert, via power means, into sentence-level scores. We combine this sentence-level score with the original metric to obtain a better metric. Our extensive evaluation and analysis across 5 datasets, 5 metrics and 4 explainability techniques shows that some configurations reliably improve the original metrics' correlation with human judgment. On two held datasets for testing, we obtain improvements in 15/18 resp. 4/4 cases. The gains in Pearson correlation are up to 0.032 resp. 0.055. We make our code available.

Video understanding is a growing field and a subject of intense research, which includes many interesting tasks to understanding both spatial and temporal information, e.g., action detection, action recognition, video captioning, video retrieval. One of the most challenging problems in video understanding is dealing with feature extraction, i.e. extract contextual visual representation from given untrimmed video due to the long and complicated temporal structure of unconstrained videos. Different from existing approaches, which apply a pre-trained backbone network as a black-box to extract visual representation, our approach aims to extract the most contextual information with an explainable mechanism. As we observed, humans typically perceive a video through the interactions between three main factors, i.e., the actors, the relevant objects, and the surrounding environment. Therefore, it is very crucial to design a contextual explainable video representation extraction that can capture each of such factors and model the relationships between them. In this paper, we discuss approaches, that incorporate the human perception process into modeling actors, objects, and the environment. We choose video paragraph captioning and temporal action detection to illustrate the effectiveness of human perception based-contextual representation in video understanding.

随着需要大量数据和计算的大数据工作负载的日益增长的复杂性，数据中心每天都会消耗大量功率。为了最大程度地减少数据中心功耗，几项研究开发了功率模型，可用于调度工作，以减少主动服务器的数量或在其峰值能效点上跨服务器平衡工作负载。由于软件和硬件异质性的增加，我们观察到没有单个功率模型可适用于所有服务器条件。一些复杂的机器学习模型本身会产生性能和电源开销，因此不希望经常使用它们。没有电源模型考虑容器化工作负载执行。在本文中，我们提出了一个混合服务器电源模型Hydra，该模型考虑了预测准确性和性能开销。 Hydra动态选择给定服务器条件的最佳功率模型。与最先进的解决方案相比，Hydra在异质服务器上的所有计算强度级别上的表现都优于所有计算机。

跨核心联合学习利用了几百个可靠的数据筒仓，并具有高速访问链接，共同训练模型。尽管这种方法成为联合学习中的流行环境，但设计出强大的拓扑以减少训练时间仍然是一个开放的问题。在本文中，我们提出了一种用于跨核心联合学习的新的多编码拓扑。我们首先使用覆盖图构造多式图。然后，我们将此多数分析为具有孤立节点的不同简单图。隔离节点的存在使我们能够执行模型聚合而无需等待其他节点，从而减少训练时间。我们进一步提出了一种新的分布式学习算法，以与我们的多编码拓扑一起使用。公共数据集的密集实验表明，与最近的最新拓扑相比，我们提出的方法大大减少了训练时间，同时确保收敛并保持模型的准确性。

本文介绍了视听场景分类（SC）的任务，其中输入视频被分类为五个现实生活中拥挤的场景中的一个：'骚乱'，'噪音 - 街道'，'Firework-event'，'Music-event'和“运动氛围”。为此，我们首先从YouTube（野外场景中）收集这五个拥挤的上下文的音频视觉数据集（视频）。然后，建议广泛的深度学习框架独立地部署音频或视觉输入数据。最后，从高级深度学习框架获得的结果融合以实现最佳的准确度分数。我们的实验结果表明，音频和视觉输入因素独立贡献了SC任务的性能。值得注意的是，深入学习框架的集合探索音频或视觉输入数据的最佳精度为95.7％。

高级深度学习（DL）算法可以预测患者基于乳房成像报告和数据系统（BI-RAD）和密度标准的患者发育乳腺癌的风险。最近的研究表明，多视图分析的结合改善了整体乳房考试分类。在本文中，我们提出了一种新的多视图DL方法，用于乳房X线照片的Bi-RAD和密度评估。所提出的方法首先部署深度卷积网络，用于分别对每个视图进行特征提取。然后将提取的特征堆叠并馈入光梯度升压机（LightGBM）分类器中以预测Bi-RAD和密度分数。我们对内部乳房数据集和公共数据集数字数据库进行广泛的实验，用于筛选乳房X线摄影（DDSM）。实验结果表明，所提出的方法在两个基准数据集中突出了巨大的边距（内部数据集5％，DDSM数据集10％）优于两个基准分类方法。这些结果突出了组合多视图信息来改善乳腺癌风险预测性能的重要作用。

Here, we demonstrate how machine learning enables the prediction of comonomers reactivity ratios based on the molecular structure of monomers. We combined multi-task learning, multi-inputs, and Graph Attention Network to build a model capable of predicting reactivity ratios based on the monomers chemical structures.

Modern deep neural networks have achieved superhuman performance in tasks from image classification to game play. Surprisingly, these various complex systems with massive amounts of parameters exhibit the same remarkable structural properties in their last-layer features and classifiers across canonical datasets. This phenomenon is known as "Neural Collapse," and it was discovered empirically by Papyan et al. \cite{Papyan20}. Recent papers have theoretically shown the global solutions to the training network problem under a simplified "unconstrained feature model" exhibiting this phenomenon. We take a step further and prove the Neural Collapse occurrence for deep linear network for the popular mean squared error (MSE) and cross entropy (CE) loss. Furthermore, we extend our research to imbalanced data for MSE loss and present the first geometric analysis for Neural Collapse under this setting.

Machine Reading Comprehension has become one of the most advanced and popular research topics in the fields of Natural Language Processing in recent years. The classification of answerability questions is a relatively significant sub-task in machine reading comprehension; however, there haven't been many studies. Retro-Reader is one of the studies that has solved this problem effectively. However, the encoders of most traditional machine reading comprehension models in general and Retro-Reader, in particular, have not been able to exploit the contextual semantic information of the context completely. Inspired by SemBERT, we use semantic role labels from the SRL task to add semantics to pre-trained language models such as mBERT, XLM-R, PhoBERT. This experiment was conducted to compare the influence of semantics on the classification of answerability for the Vietnamese machine reading comprehension. Additionally, we hope this experiment will enhance the encoder for the Retro-Reader model's Sketchy Reading Module. The improved Retro-Reader model's encoder with semantics was first applied to the Vietnamese Machine Reading Comprehension task and obtained positive results.
