About

Quality and reliability of AI systems currently become a pressing concern, where many industry sectors demand a certain level of quality guarantee so that the AI systems can be eventually adopted, especially for safety- and mission-critical domains. In practice, an AI system can often be rather complex in nature, spanning AI models, traditional software components, and their interactions. Lei Ma’s research focuses on providing both fundamental quality assurance methodology and systematic engineering support for building complex AI systems to make them more reliable, safe and secure, bridging the gap between AI and its real-world applications. He is continuously proposing novel techniques of quality assessment, quality issue detection, localization, root cause analysis, repairing, etc., specially designed for both AI models at the unit level and AI systems at the whole system level, to address the AI quality concerns across domains, e.g., autonomous driving, video games, DeepFake, healthcare, etc.
