5G新技术架构的引入和业务场景的多样性给智能化网络运维 (AIOps) 带来了新的挑战。无线网络故障根因定位是网络运维中的一个重要环节，通过快速且准确地判断出网络故障的根因，技术人员可以及时采取措施对网络进行修复。然而，现网经常受困于复杂的无线通信环境和网络部署结构，且存在网络故障样本数少、不同的场景下故障表征差异性大等问题。如何充分利用领域知识和一小部分标定数据，使用统计学习和因果推断技术，快速准确地定位故障的根因，是网络运维面临的巨大挑战。
ICASSP（International Conference on Acoustics, Speech and Signal Processing）是全世界最大的，也是最全面的融合信号处理、统计学习、及无线通信的综合性顶级会议。ICASSP-2022将于5月22日-27日在新加坡举行。
Localizing the root cause of network faults is crucial to network operation and maintenance. Significant operational expenses will be saved if the root cause can be identified agilely and accurately. However, this is challenging for human beings due to the complicated wireless environments and network architectures. Resorting to data analysis and machine learning is promising but remains difficult due to various practical difficulties, such as the lack of well-labeled samples, hybrid fault behaviors, missing data, and so on. The overall target of this competition is to help people better understand the root cause localization problem and open up new paths for the next-generation wireless networks empowered by causal inference techniques.
We provide a novel real-world telecommunication dataset collected from live 5G networks, together with the associated causal graph endorsed by human experts. Various practical problems were born with this dataset due to the underlying system limitations, such as how to efficiently handle the short of well-labeled data, how to handle the missing data issue, how to combine classic time series analysis with new-fashioned learning-based models, how to perform accurate and reliable causal inference, and so on. We hope these interesting problems can arouse the broad attention of scholars as well as practitioners with different backgrounds and inspire new ideas during the competition. Full support on the data and platform will be provided by the organizing team.
This competition is organized and supported by CUHKSZ-SRIBD-HUAWEI Innovation Laboratory for Future Network Systems Optimization.
