Abstract: 

The recent development of artificial intelligence (AI) promises a future of data-driven automation that can replace most of today/s human efforts. However, currently most AI-enabled systems—often functioning as 'black boxes'—struggle to accommodate, learn from or communicate with humans. One fundamental problem is a limited interaction bandwidth between human and AI: currently, AI's development is bestowed upon the few experts; for users in non-computing domains, there is limited support for them to comprehend, customize or collaborate with AI. As we are on the cusp of defining the future of human-AI relationship, it is important to create new interaction channels to bridge AI and non-computing users. In this talk, I will discuss three research thrusts for expanding the interaction bandwidth between human and AI:

 

Human ← AI: making AI comprehensible to non-computing domain users. Going beyond system-centered prior work that focused on generic explainable representations of AI (XAI), my research takes a user-centered approach: for example, CheXplain is a system co-designed via iterative studies with medical professionals, which enables referring physicians to explore and understand AI's diagnosis on chest X-ray images.

 

Human → AI: enabling non-computing domain users to customize AI. Contrary to providing a single label and relying on AI to reverse-engineer the reasoning process, my research investigates techniques for users to express their domain knowledge in ways that are understandable and learnable to an AI: for example, Robiot employs computer vision to interpret a user's demonstration of a physical task, which is translated in a vocabulary that informs an AI to generate robotic mechanisms to automate such tasks. 

 

Human ↔ AI: supporting collaboration between non-computing domain users and AI. Building upon comprehensible and customizable AI, my research takes an integrated approach that creates an environment to support human-AI collaboration: for example, Forte allows a mechanical engineer to sketch a high-level functional and aesthetic design while an AI handles the low-level generation of structures that realizes such design.
