由于标记医学图像数据是一个昂贵且劳动密集型的过程，因此近年来，Active学习在医学图像分割领域中广受欢迎。文献中已经提出了各种积极的学习策略，但是它们的有效性高度取决于数据集和培训方案。为了促进现有策略的比较，并为评估新策略提供了基准，我们评估了从医学分割的十项全能中的三个数据集上的几种著名的活跃学习策略的性能。此外，我们考虑了专门针对3D图像数据量身定制的扎实的采样策略。我们证明，随机和踩踏的采样都是强大的基准，并讨论了研究方法的优势和缺点。为了允许其他研究人员将他们的工作与我们的结果进行比较，我们提供了一个开源框架，以在各种医疗分割数据集上对主动学习策略进行基准测试。

The evolution of wireless communications into 6G and beyond is expected to rely on new machine learning (ML)-based capabilities. These can enable proactive decisions and actions from wireless-network components to sustain quality-of-service (QoS) and user experience. Moreover, new use cases in the area of vehicular and industrial communications will emerge. Specifically in the area of vehicle communication, vehicle-to-everything (V2X) schemes will benefit strongly from such advances. With this in mind, we have conducted a detailed measurement campaign with the purpose of enabling a plethora of diverse ML-based studies. The resulting datasets offer GPS-located wireless measurements across diverse urban environments for both cellular (with two different operators) and sidelink radio access technologies, thus enabling a variety of different studies towards V2X. The datasets are labeled and sampled with a high time resolution. Furthermore, we make the data publicly available with all the necessary information to support the on-boarding of new researchers. We provide an initial analysis of the data showing some of the challenges that ML needs to overcome and the features that ML can leverage, as well as some hints at potential research studies.
