联合学习（FL）是一个分布式的机器学习范式，可从分散的私人数据集中进行学习模型，在该数据集中将标签工作委托给客户。尽管大多数现有的FL方法都假定用户的设备很容易获得高质量的标签。实际上，标签噪声自然会发生在FL中，并遵循非i.i.d。客户之间的分布。由于非IID的挑战，现有的最先进的集中式方法表现出不令人满意的性能，而先前的FL研究依靠数据交换或重复的服务器端援助来提高模型的性能。在这里，我们提出了Fedln，这是一个框架，可以在不同的FL训练阶段处理标签噪声；即，FL初始化，设备模型培训和服务器模型聚合。具体而言，FedLN在单个联合回合中计算每客户噪声级估计，并通过纠正（或限制）噪声样本的效果来改善模型的性能。与其他现有方法相比，对各种公开视觉和音频数据集的广泛实验平均提高了24％，标签噪声水平为70％。我们进一步验证了FedLN在人类通知的现实世界嘈杂数据集中的效率，并报告了模型的识别率平均增长了9％，这强调了FEDLN对于改善提供给日常用户的FL服务很有用。

Implicit Neural Representations (INR) have recently shown to be powerful tool for high-quality video compression. However, existing works are limiting as they do not explicitly exploit the temporal redundancy in videos, leading to a long encoding time. Additionally, these methods have fixed architectures which do not scale to longer videos or higher resolutions. To address these issues, we propose NIRVANA, which treats videos as groups of frames and fits separate networks to each group performing patch-wise prediction. This design shares computation within each group, in the spatial and temporal dimensions, resulting in reduced encoding time of the video. The video representation is modeled autoregressively, with networks fit on a current group initialized using weights from the previous group's model. To further enhance efficiency, we perform quantization of the network parameters during training, requiring no post-hoc pruning or quantization. When compared with previous works on the benchmark UVG dataset, NIRVANA improves encoding quality from 37.36 to 37.70 (in terms of PSNR) and the encoding speed by 12X, while maintaining the same compression rate. In contrast to prior video INR works which struggle with larger resolution and longer videos, we show that our algorithm is highly flexible and scales naturally due to its patch-wise and autoregressive designs. Moreover, our method achieves variable bitrate compression by adapting to videos with varying inter-frame motion. NIRVANA achieves 6X decoding speed and scales well with more GPUs, making it practical for various deployment scenarios.
