profile


My current research focuses is on innovative approaches of computing personalization and incorporating personalization analytics into service design. In the healthcare domain, I am working on active characterization of personal wellness status and active recommendation that are driven by outcome prediction. The importance of personalization research and system design arises from the need of serving the long tail of user need. While many multi-year structured programs have verified the effectiveness of individualized intervention on preventive care and chronic disease management (Helmrich et al, 1991; Bailey, 2001; Finland National Type II Diabetes Prevention Programme, 2007; CDC Diabetes Prevention Program, 2008), the task of offering personalized services dynamically in users’ context has posed grand challenges to existing service providers. On the one hand, integrated care models have shown promises in satisfying the long tail of demand. On the other hand, the success of an integrated model in clinical trials is not enough to secure a disruption in the service market. In fact, its reliance on the constant updates of user wellness status and tailoring of intervention accordingly requires solid system support from both the vendors and system operators. Some key competencies to be provided include: (1) inferring risks from multiple heterogeneous sources (and whenever necessary, going back to the user and care team to solicit for more information); (2) handling multi-faceted risk stratification; and (3) “on the fly” assessment and recommendation with respect to trends shown in the incoming data stream. During the process of data analytics, I am also quite interested in using social signals to improve compliance feedback strategy.

I am involved in the development of an evidence-based wellness management platform in a cloud computing environment. The platform provides an API for healthcare applications to (i) integrate information from heterogeneous data source (Sense), (ii) draw predictions by applying or extending models in a repository (Predict), and (iii) trigger proper responses (Respond). The development side of goal is to enable any independent software vendor (ISV) to use the API and the Sense-Predict-Respond framework to implement their services and exchange information with 3rd party applications.

Overarching Theme & Previous Work

 

The overarching them of my research interest ties closely to the marriage of artificial intelligence and human computer interaction, with a focus on integrating machine learning and empirical analysis approaches for natural language understanding. My previous research concerns the development of spoken language understanding applications in spontaneous speech, using a variety of approaches ranging from statistical analysis, empirical study to machine learning. This is no secret that people speak differently under different circumstances. Some of the differences are systematic and can be attributed to deeper differences, such as the intention of speaker.

My contribution to this problem is to develop a learning framework that can be used to identify multimodal features (and patterns) that are characteristics of the systematic differences in human conversations and to build automatic detection mechanisms that are robust to spontaneous speech effects. Current projects include automatic topic segmentation and labeling and automatic decision detection. The overarching goal is to provide visual aids at the right level of details for the users to find information from the often-lengthy archives of conversation recordings.
