Outline

We aim to establish the foundation of human computation for designing trustworthy human-AI collaborative systems by (i) human-in-the-loop machine learning for human-AI collaborative data analytics, (ii) defining and optimizing reliability and trust for human computation systems, (iii) addressing ethical issues for social acceptance of human computation, and (iv) supporting human intellectual and creative activities and developing human capabilities through human computation.

Outline

We develop fundamental technologies for energy-efficient distributed AI systems based on federated learning for respecting the diversity of users and data and the spatial and temporal environmental variations. We define D3-AI as the distributed AI with four reliability capabilities: privacy, fairness, dynamic adaptability, and energy efficiency. We pursue researches on the fundamental technologies and applications of D3-AI in collaboration with machine learning theory, computer architecture, IoT platform, and data processing.

Outline

We develop a mathematical and computational framework for assessing the reliability of AI-driven hypotheses for AI-driven science and technology by extending the traditional statistical hypothesis testing framework. Our main focus is to develop new theories, algorithms, and software for statistical hypothesis testing that is valid for adaptively constructed AI-driven hypotheses. We study AI-driven hypotheses in static and dynamic environments and pursue how to evaluate their reliability from both theoretical and practical perspectives. We develop a protocol for evaluating the reliability of AI medical technology based on the mathematical and computational framework and demonstrate the protocol through the development of an AI-based pathological diagnosis system for malignant lymphoma.

Outline

Our purpose is to build human-AI cooperative decision-making systems for trustworthy AI. In this project, we develop trust calibration AI (TCAI) which can detect over/under-trust by monitoring humans’ selection behaviors in human-AI collaboration and adaptively facilitate humans’ trust calibration by themselves. The TCAI uses calibration cues as stimuli that facilitate humans’ voluntary trust calibration. Finally, we apply the TCAI to human-AI cooperative imaging diagnosis and medical examination.
