Focused Research Areas
Joint Analysis of Text and Behavior Data
Build probabilistic generative models for unifying the analyses of the latent structures and correspondence in human-generated text data and behavior data to get a comprehensive understanding of users' underlying intents. Read More
Task-based Online Interactive Decision Optimization
Organize users' longitudinal information seeking activities into tasks, and develop online learning algorithms to proactively infer users intents and dynamically adapt the systems from interactions with humans for long-term optimality. Read More
Immediately Scalable Sensing in Buildings
Estimate the sensor data of one building based on sensor data collected in other buildings. The basic premise is that common design and construction patterns for buildings create a repeating structure in their sensor data. Read More
Automatic Metadata Mapping for Scalable Building Analytics
Create a suite of automated mapping solutions that will allow an analytics engine to quickly connect to and analyze the data from an unfamiliar building. This research enables building analytics to be applied at scale. Read More
Privacy-Preserving Personalization
Provide meaningful privacy guarantees by obfuscating users' search behaviors via probabilistic generative models, and develop algorithmic methods to evaluate the cost and privacy benefits of different obfuscation techniques. Read More
