Our primary research areas are unsupervised learning, deep learning, graph learning, mainly applied in intelligent operation and maintenance, fintech and other fields. Based on our science and technology development strategy of PES (Professional service, Enabling ecology, Science and technology for good), we create instant, efficient, simple and easy to use AI technology, and explore innovation in the field of intelligent operation and financial technology. At present, we have created root cause positioning, abnormal detection, jitter noise reduction and other technologies for 'Weiying Cloud' (intelligent operation and maintenance) products.
