The Internet of Senses (IoS) holds the promise of flawless telepresence-style communication for all human `receptors' and therefore blurs the difference of virtual and real environments. We commence by highlighting the compelling use cases empowered by the IoS and also the key network requirements. We then elaborate on how the emerging semantic communications and Artificial Intelligence (AI)/Machine Learning (ML) paradigms along with 6G technologies may satisfy the requirements of IoS use cases. On one hand, semantic communications can be applied for extracting meaningful and significant information and hence efficiently exploit the resources and for harnessing a priori information at the receiver to satisfy IoS requirements. On the other hand, AI/ML facilitates frugal network resource management by making use of the enormous amount of data generated in IoS edge nodes and devices, as well as by optimizing the IoS performance via intelligent agents. However, the intelligent agents deployed at the edge are not completely aware of each others' decisions and the environments of each other, hence they operate in a partially rather than fully observable environment. Therefore, we present a case study of Partially Observable Markov Decision Processes (POMDP) for improving the User Equipment (UE) throughput and energy consumption, as they are imperative for IoS use cases, using Reinforcement Learning for astutely activating and deactivating the component carriers in carrier aggregation. Finally, we outline the challenges and open issues of IoS implementations and employing semantic communications, edge intelligence as well as learning under partial observability in the IoS context.

Automatic segmentation is essential for the brain tumor diagnosis, disease prognosis, and follow-up therapy of patients with gliomas. Still, accurate detection of gliomas and their sub-regions in multimodal MRI is very challenging due to the variety of scanners and imaging protocols. Over the last years, the BraTS Challenge has provided a large number of multi-institutional MRI scans as a benchmark for glioma segmentation algorithms. This paper describes our contribution to the BraTS 2022 Continuous Evaluation challenge. We propose a new ensemble of multiple deep learning frameworks namely, DeepSeg, nnU-Net, and DeepSCAN for automatic glioma boundaries detection in pre-operative MRI. It is worth noting that our ensemble models took first place in the final evaluation on the BraTS testing dataset with Dice scores of 0.9294, 0.8788, and 0.8803, and Hausdorf distance of 5.23, 13.54, and 12.05, for the whole tumor, tumor core, and enhancing tumor, respectively. Furthermore, the proposed ensemble method ranked first in the final ranking on another unseen test dataset, namely Sub-Saharan Africa dataset, achieving mean Dice scores of 0.9737, 0.9593, and 0.9022, and HD95 of 2.66, 1.72, 3.32 for the whole tumor, tumor core, and enhancing tumor, respectively.

The number of international benchmarking competitions is steadily increasing in various fields of machine learning (ML) research and practice. So far, however, little is known about the common practice as well as bottlenecks faced by the community in tackling the research questions posed. To shed light on the status quo of algorithm development in the specific field of biomedical imaging analysis, we designed an international survey that was issued to all participants of challenges conducted in conjunction with the IEEE ISBI 2021 and MICCAI 2021 conferences (80 competitions in total). The survey covered participants' expertise and working environments, their chosen strategies, as well as algorithm characteristics. A median of 72% challenge participants took part in the survey. According to our results, knowledge exchange was the primary incentive (70%) for participation, while the reception of prize money played only a minor role (16%). While a median of 80 working hours was spent on method development, a large portion of participants stated that they did not have enough time for method development (32%). 25% perceived the infrastructure to be a bottleneck. Overall, 94% of all solutions were deep learning-based. Of these, 84% were based on standard architectures. 43% of the respondents reported that the data samples (e.g., images) were too large to be processed at once. This was most commonly addressed by patch-based training (69%), downsampling (37%), and solving 3D analysis tasks as a series of 2D tasks. K-fold cross-validation on the training set was performed by only 37% of the participants and only 50% of the participants performed ensembling based on multiple identical models (61%) or heterogeneous models (39%). 48% of the respondents applied postprocessing steps.

可持续性需要提高能源效率，而最小的废物则需要提高能源效率。因此，未来的电力系统应提供高水平的灵活性IIN控制能源消耗。对于能源行业的决策者和专业人员而言，对未来能源需求/负载的精确预测非常重要。预测能源负载对能源提供者和客户变得更有优势，使他们能够建立有效的生产策略以满足需求。这项研究介绍了两个混合级联模型，以预测不同分辨率中的多步户家庭功耗。第一个模型将固定小波变换（SWT）集成为有效的信号预处理技术，卷积神经网络和长期短期记忆（LSTM）。第二种混合模型将SWT与名为Transformer的基于自我注意的神经网络结构相结合。使用时频分析方法（例如多步预测问题中的SWT）的主要限制是，它们需要顺序信号，在多步骤预测应用程序中有问题的信号重建问题。级联模型可以通过使用回收输出有效地解决此问题。实验结果表明，与现有的多步电消耗预测方法相比，提出的混合模型实现了出色的预测性能。结果将为更准确和可靠的家庭用电量预测铺平道路。

Glioblastomas是最具侵略性的快速生长的主要脑癌，起源于大脑的胶质细胞。准确鉴定恶性脑肿瘤及其子区域仍然是医学图像分割中最具挑战性问题之一。脑肿瘤分割挑战（Brats）是自动脑胶质细胞瘤分割算法的流行基准，自于其启动。在今年的挑战中，Brats 2021提供了2,000名术前患者的最大多参数（MPMRI）数据集。在本文中，我们提出了两个深度学习框架的新聚合，即在术前MPMRI中的自动胶质母细胞瘤识别的Deepseg和NNU-Net。我们的集合方法获得了92.00,87.33和84.10和Hausdorff距离为3.81,8.91和16.02的骰子相似度分数，用于增强肿瘤，肿瘤核心和全肿瘤区域，单独进行。这些实验结果提供了证据表明它可以在临床上容易地应用，从而助攻脑癌预后，治疗计划和治疗反应监测。

提供可靠的连接到蜂窝连接的无人机可以非常具有挑战性;它们的性能高度取决于周围环境的性质，例如地面BSS的密度和高度。另一方面，高层建筑可能阻断来自地面BS的不期望的干扰信号，从而提高了UVS与其服务BS之间的连接。为了解决此类环境中的无人机的连接，本文提出了一种RL算法，以动态优化UAV的高度，因为它在通过环境中移动，目标是提高其经历的吞吐量。所提出的解决方案是使用来自爱尔兰都柏林市中心的两个不同地点的实验获得的测量来评估。在第一场景中，UAV连接到宏小区，而在第二场景中，UAV将在双层移动网络中关联到不同的小单元。结果表明，与基线方法相比，该溶液的吞吐量增加了6％至41％。
