我们考虑了在透明的蜂窝车辆到所有物品（C-V2X）系统中的联合渠道分配和电力分配的问题，其中多个车辆到网络（V2N）上行链路共享与多个车辆到车辆的时频资源（ v2v）排，使连接和自动驾驶汽车的团体可以紧密地一起旅行。由于在车辆环境中使用高用户移动性的性质，依赖全球渠道信息的传统集中优化方法在具有大量用户的C-V2X系统中可能不可行。利用多机构增强学习（RL）方法，我们提出了分布式资源分配（RA）算法来克服这一挑战。具体而言，我们将RA问题建模为多代理系统。仅基于本地渠道信息，每个排领导者充当代理，共同相互交互，因此选择了子频段和功率水平的最佳组合来传输其信号。为此，我们利用双重Q学习算法在同时最大化V2N链接的总和率的目标下共同训练代理，并满足所需延迟限制的每个V2V链接的数据包输送概率。仿真结果表明，与众所周知的详尽搜索算法相比，我们提出的基于RL的算法提供了紧密的性能。

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.

We present NusaCrowd, a collaborative initiative to collect and unite existing resources for Indonesian languages, including opening access to previously non-public resources. Through this initiative, we have has brought together 137 datasets and 117 standardized data loaders. The quality of the datasets has been assessed manually and automatically, and their effectiveness has been demonstrated in multiple experiments. NusaCrowd's data collection enables the creation of the first zero-shot benchmarks for natural language understanding and generation in Indonesian and its local languages. Furthermore, NusaCrowd brings the creation of the first multilingual automatic speech recognition benchmark in Indonesian and its local languages. Our work is intended to help advance natural language processing research in under-represented languages.

在光场压缩中，基于图的编码功能强大，可以利用沿着不规则形状的信号冗余并获得良好的能量压实。然而，除了高度复杂性到处理高维图外，它们的图形构造方法对观点之间的差异信息的准确性非常敏感。在计算机软件生成的现实世界光场或合成光场中，由于渐晕效果和两种类型的光场视图之间的视图之间的巨大差异，将视差信息用于超射线投影可能会遭受不准确性。本文介绍了两种新型投影方案，导致差异信息的错误较小，其中一个投影方案还可以显着降低编码器和解码器的时间计算。实验结果表明，与原始投影方案和基于HEVC或基于JPEG PLENO的编码方法相比，使用这些建议可以大大增强超级像素的投影质量，以及率延伸性能。

在过去的二十年中，我们看到万维网的链接结构被建模为有向图。在本文中，我们将将万维网的链接结构建模为定向超图。此外，我们将为该定向超图开发Pagerank算法。由于缺乏万维网定向HyperGraph数据集，我们将将Pagerank算法应用于代谢网络，该网络是定向的HyperGraph本身。实验表明，我们的新型Pagerank算法成功地应用于该代谢网络。
