自动扬声器验证（ASV）已在现实生活中广泛用于身份认证。但是，随着语音转换的快速发展，语音合成算法和记录设备质量的提高，ASV系统很容易受到欺骗攻击。近年来，有关合成和重播语音检测的许多作品，研究人员提出了许多基于手工制作的特征的反欺骗方法，以提高合成和重播语音检测系统的准确性和鲁棒性。但是，使用手工制作的功能而不是原始波形将丢失某些信息进行抗旋转，这将降低系统的检测性能。受图像分类任务中Convnext的有希望的性能的启发，我们将Convnext网络体系结构相应地扩展到SPOOF攻击任务，并提出了端到端的反欺骗模型。通过将扩展体系结构与频道注意块相结合，提出的模型可以专注于最有用的语音表示子频段，以改善反欺骗性的性能。实验表明，对于ASVSPOOF 2019 LA评估数据集和PA评估数据集，我们提出的最佳单个系统可以达到1.88％和2.79％的误差率，这证明了该模型的抗SpoFofing能力。

State space models (SSMs) have demonstrated state-of-the-art sequence modeling performance in some modalities, but underperform attention in language modeling. Moreover, despite scaling nearly linearly in sequence length instead of quadratically, SSMs are still slower than Transformers due to poor hardware utilization. In this paper, we make progress on understanding the expressivity gap between SSMs and attention in language modeling, and on reducing the hardware barrier between SSMs and attention. First, we use synthetic language modeling tasks to understand the gap between SSMs and attention. We find that existing SSMs struggle with two capabilities: recalling earlier tokens in the sequence and comparing tokens across the sequence. To understand the impact on language modeling, we propose a new SSM layer, H3, that is explicitly designed for these abilities. H3 matches attention on the synthetic languages and comes within 0.4 PPL of Transformers on OpenWebText. Furthermore, a hybrid 125M-parameter H3-attention model that retains two attention layers surprisingly outperforms Transformers on OpenWebText by 1.0 PPL. Next, to improve the efficiency of training SSMs on modern hardware, we propose FlashConv. FlashConv uses a fused block FFT algorithm to improve efficiency on sequences up to 8K, and introduces a novel state passing algorithm that exploits the recurrent properties of SSMs to scale to longer sequences. FlashConv yields 2$\times$ speedup on the long-range arena benchmark and allows hybrid language models to generate text 1.6$\times$ faster than Transformers. Using FlashConv, we scale hybrid H3-attention language models up to 1.3B parameters on the Pile and find promising initial results, achieving lower perplexity than Transformers and outperforming Transformers in zero- and few-shot learning on a majority of tasks in the SuperGLUE benchmark.

Three main points: 1. Data Science (DS) will be increasingly important to heliophysics; 2. Methods of heliophysics science discovery will continually evolve, requiring the use of learning technologies [e.g., machine learning (ML)] that are applied rigorously and that are capable of supporting discovery; and 3. To grow with the pace of data, technology, and workforce changes, heliophysics requires a new approach to the representation of knowledge.

In the Earth's magnetosphere, there are fewer than a dozen dedicated probes beyond low-Earth orbit making in-situ observations at any given time. As a result, we poorly understand its global structure and evolution, the mechanisms of its main activity processes, magnetic storms, and substorms. New Artificial Intelligence (AI) methods, including machine learning, data mining, and data assimilation, as well as new AI-enabled missions will need to be developed to meet this Sparse Data challenge.

Semantic communication (SemCom) and edge computing are two disruptive solutions to address emerging requirements of huge data communication, bandwidth efficiency and low latency data processing in Metaverse. However, edge computing resources are often provided by computing service providers and thus it is essential to design appealingly incentive mechanisms for the provision of limited resources. Deep learning (DL)- based auction has recently proposed as an incentive mechanism that maximizes the revenue while holding important economic properties, i.e., individual rationality and incentive compatibility. Therefore, in this work, we introduce the design of the DLbased auction for the computing resource allocation in SemComenabled Metaverse. First, we briefly introduce the fundamentals and challenges of Metaverse. Second, we present the preliminaries of SemCom and edge computing. Third, we review various incentive mechanisms for edge computing resource trading. Fourth, we present the design of the DL-based auction for edge resource allocation in SemCom-enabled Metaverse. Simulation results demonstrate that the DL-based auction improves the revenue while nearly satisfying the individual rationality and incentive compatibility constraints.

Edge-assisted vehicle-to-everything (V2X) motion planning is an emerging paradigm to achieve safe and efficient autonomous driving, since it leverages the global position information shared among multiple vehicles. However, due to the imperfect channel state information (CSI), the position information of vehicles may become outdated and inaccurate. Conventional methods ignoring the communication delays could severely jeopardize driving safety. To fill this gap, this paper proposes a robust V2X motion planning policy that adapts between competitive driving under a low communication delay and conservative driving under a high communication delay, and guarantees small communication delays at key waypoints via power control. This is achieved by integrating the vehicle mobility and communication delay models and solving a joint design of motion planning and power control problem via the block coordinate descent framework. Simulation results show that the proposed driving policy achieves the smallest collision ratio compared with other benchmark policies.

三维荧光显微镜通常遭受各向异性的影响，沿轴向方向的分辨率低于侧面成像平面内的分辨率。我们通过提出双周期来解决此问题，这是双环荧光图像的关节反卷积和融合的新框架。受到最近的神经清性方法的启发，双周期被设计为一种循环一致的生成网络，通过结合双视发电机和先前引导的退化模型，以自我监督的方式训练。我们在合成数据和真实数据上验证双周期，显示其最先进的性能，而无需任何外部培训数据。

可重新配置的智能表面（RIS）可以显着增强TERA-HERTZ大量多输入多输出（MIMO）通信系统的服务覆盖范围。但是，获得有限的飞行员和反馈信号开销的准确高维通道状态信息（CSI）具有挑战性，从而严重降低了常规空间分裂多次访问的性能。为了提高针对CSI缺陷的鲁棒性，本文提出了针对RIS辅助TERA-HERTZ多用户MIMO系统的基于深度学习的（DL）基于速率的多访问（RSMA）方案。具体而言，我们首先提出了基于DL的混合数据模型驱动的RSMA预编码方案，包括RIS的被动预编码以及模拟主动编码和基本站（BS）的RSMA数字活动预码。为了实现RIS的被动预码，我们提出了一个基于变压器的数据驱动的RIS反射网络（RRN）。至于BS的模拟主动编码，我们提出了一个基于匹配器的模拟预编码方案，因为BS和RIS采用了Los-Mimo天线阵列结构。至于BS的RSMA数字活动预码，我们提出了一个低复杂性近似加权的最小均方误差（AWMMSE）数字编码方案。此外，为了更好地编码性能以及较低的计算复杂性，模型驱动的深层展开的主动编码网络（DFAPN）也是通过将所提出的AWMMSE方案与DL相结合的。然后，为了在BS处获得准确的CSI，以实现提高光谱效率的RSMA预编码方案，我们提出了一个CSI采集网络（CAN），具有低飞行员和反馈信号开销，下行链接飞行员的传输，CSI在此处使用CSI的CSI反馈。 （UES）和BS处的CSI重建被建模为基于变压器的端到端神经网络。

现有的数据驱动和反馈流量控制策略不考虑实时数据测量的异质性。此外，对于缺乏数据效率，传统的加固学习方法（RL）方法通常会缓慢收敛。此外，常规的最佳外围控制方案需要对系统动力学的精确了解，因此对内源性不确定性会很脆弱。为了应对这些挑战，这项工作提出了一种基于不可或缺的增强学习（IRL）的方法来学习宏观交通动态，以进行自适应最佳周边控制。这项工作为运输文献做出了以下主要贡献：（a）开发连续的时间控制，并具有离散增益更新以适应离散时间传感器数据。 （b）为了降低采样复杂性并更有效地使用可用数据，将体验重播（ER）技术引入IRL算法。 （c）所提出的方法以“无模型”方式放松模型校准的要求，该方式可以稳健地进行建模不确定性，并通过数据驱动的RL算法增强实时性能。 （d）通过Lyapunov理论证明了基于IRL的算法和受控交通动力学的稳定性的收敛性。最佳控制定律被参数化，然后通过神经网络（NN）近似，从而缓解计算复杂性。在不需要模型线性化的同时，考虑了状态和输入约束。提出了数值示例和仿真实验，以验证所提出方法的有效性和效率。

ICECUBE是一种用于检测1 GEV和1 PEV之间大气和天体中微子的光学传感器的立方公斤阵列，该阵列已部署1.45 km至2.45 km的南极的冰盖表面以下1.45 km至2.45 km。来自ICE探测器的事件的分类和重建在ICeCube数据分析中起着核心作用。重建和分类事件是一个挑战，这是由于探测器的几何形状，不均匀的散射和冰中光的吸收，并且低于100 GEV的光，每个事件产生的信号光子数量相对较少。为了应对这一挑战，可以将ICECUBE事件表示为点云图形，并将图形神经网络（GNN）作为分类和重建方法。 GNN能够将中微子事件与宇宙射线背景区分开，对不同的中微子事件类型进行分类，并重建沉积的能量，方向和相互作用顶点。基于仿真，我们提供了1-100 GEV能量范围的比较与当前ICECUBE分析中使用的当前最新最大似然技术，包括已知系统不确定性的影响。对于中微子事件分类，与当前的IceCube方法相比，GNN以固定的假阳性速率（FPR）提高了信号效率的18％。另外，GNN在固定信号效率下将FPR的降低超过8（低于半百分比）。对于能源，方向和相互作用顶点的重建，与当前最大似然技术相比，分辨率平均提高了13％-20％。当在GPU上运行时，GNN能够以几乎是2.7 kHz的中位数ICECUBE触发速率的速率处理ICECUBE事件，这打开了在在线搜索瞬态事件中使用低能量中微子的可能性。
