- Next Generation Multi-scenario and Multi-modal Heterogeneous Computing Engines
Our research focuses on fusing and unifying various computing paradigms such as batch processing, streaming, and interactive analysis, by developing new technologies such as approximate and progressive query processing. This will be utilized to empower next-generation computing engines used by real-world applications at Alibaba, and to facilitate efficient execution of hybrid workloads including traditional data analytics, graph computing, and machine learning.
Meanwhile, the lab studies how to leverage and integrate high-performance heterogeneous hardware, such as GPU, FPGA, and ASIC, with general-purpose computing engines to enhance their power. This will be utilized to better meet the requirements of data-intensive computation such as artificial intelligence and large-scale data analytics.
- Algorithms and Applications of Large-scale Diverse Data Mining and Machine Learning
Our research focuses on efficient data mining and machine learning algorithms on large-scale heterogeneous data, such as structured data, graph data, and information networks. We also explore and fuse new techniques in the fields of large-scale graph representation learning and knowledge base, and applies them to scenarios such as online fraud prevention, recommendation systems, and search.
- Smart and Autonomous System
Our research focuses on powering data management and processing systems with artificial intelligence technology: artificial-intelligence techniques will be used in data-warehouse management, resource scheduling, and engine optimization to strengthen the systems and make them smarter, safer, and more reliable. Moreover, system technology will be used to assist model selection and hyperparameter search in artificial intelligence and automate machine learning.
- Data Security and Privacy Protection
Our research focuses on providing data security and protecting users’ privacy more effectively during different stages of the data pipeline. These stages include data collection, sharing, processing, and analytics, which may leak personal and sensitive information. We aim to provide acceptable data utility under strong security/privacy guarantees.
- Hyper-scale Graph Computing
Our research focuses on large-scale graph representation learning and graph-based knowledge base technologies, as well as the underlying hyper-scale graph computing engines and hyper-scale knowledge base inference systems, with the purpose of contributing to the fields of information retrieval, distributed computing, large-scale system design, machine learning, artificial intelligence, and natural language processing.
- Hyper-scale Graph Inference Engines
The data of the Alibaba ecosystem is extremely rich and varied, covering everything from shopping, travel, entertainment, and payment. Graph inference combined with deep learning has achieved successful phased results in many of Alibaba's business scenarios. Large-scale graph representations are emerging as ancillary information that can effectively use cross domain information. Thus, we can truly have better understanding the needs of consumers in different business scenarios. We are working on the development of a new generation of graph learning platform that can efficiently perform inference analysis on billions of nodes and trillions of edges.
- Solutions to E-commerce Fraud Detection
Internet fraud artifice arises as an endless stream. Alibaba is also heavily attacked by the Internet blackmail, and anti-fraud has become one of its most important tasks. Alibaba can identify tens of millions of highly suspicious devices with their traffic flow every day. Fraud detection can be roughly divided into two directions: channel equipment and traffic anti-fraud. The main task of channel devices anti-fraud is to identify suspicious simulators, equipment farms, etc. We extracted all kinds of sparse and dense features of the devices from various logs, and effectively modified Google's Wide & Deep model based on our business scenarios to identify millions of highly trusted fraudulent devices every day. The traffic anti-fraud is more related to business scenarios. By considering and modelling suspicious traffic as a whole with enhanced information, we can improve the model capability and effectively identify suspicious devices. Thus, we propose a series of graph models that are able to detect and intercept millions of cheating cookies with high accuracy from hyper-scale traffic logs every day.
