Summary of His Talk |
We live in an increasingly connected and automated society.
Smart environments embody this trend by linking computers and other devices to everyday settings and commonplace tasks. The desire to create smart environments has existed for decades, however, recent advances in smart devices, wireless and sensor networks, mobile and pervasive computing, machine learning, middleware and agent technologies have made this dream a reality. We define a `smart environment' as one that is able to autonomously acquire and apply knowledge about an environment, and adapt to its inhabitants to improve their experience.
In this talk, we will propose a learning and prediction based paradigm for designing and modeling smart home environments. The foundation of this paradigm lies in information theory in that it manages uncertainty due to the inhabitants' context (location, activity, etc.) in daily lives. The basic idea is to build compressed dictionary of context profiles collected from sensors and other monitoring devices, efficiently learn from those profiles, and optimally track and predict the inhabitant's contexts. Successful predictions help automate tasks and adaptive control of device operations as well as lead to context-aware resource management schemes. We will also show how game theory plays an important role in resolving conflicts among multiple inhabitants' preferences. Finally, we will present an overview and demo of our MavHome smart home project at UT Arlington
