Welcome to AIOps@NKU lab!

Our lab mainly focuses on artificial intelligence operations (AIOps), which applies AI methods, including traditional machine learning methods (e.g., decision tree, SVM, logistic regression), deep learning methods (e.g., Variational Autoencoder, LSTM, CNN), reinforcement learning methods (e.g., MCTS), knowledge graph methods, graph computing methods, to analyze the application-level and machine-level data of Internet-based services or Web-based services (say search engine, online shopping, online video, instant messaging). We conduct anomaly detection, root cause analysis, failure localization, failure prediction, etc., on a large volume of data to keep services reliable and improve user experience. We are now collaborating with Alibaba, Baidu, Huawei, Bytedance, Huya, and CERNET. Thus the data of these companies can be used to evaluate and optimize the model proposed by us.

We welcome more undergraduate students to join our lab. You can use real-world data to prove your idea and deploy your model to world-class companies to improve the experience of millions of users! We will recommend you to top global Internet/IT companies such as MSRA, Alibaba, Baidu, Tencent, Bytedance, Huawei, Huya, etc.

Our lab is organized by Dr. Shenglin Zhang and Dr. Yongqian sun. We have published a series of papers, which can be found here. In addition, here are the courses taught by Dr. Shenglin Zhang and Dr. Yongqian Sun.
