Online semi-supervised learning algorithms incrementally build models of objects, such as faces, and dynamically refine them over time using real-world observations. Researchers on this project team successfully used this approach to develop an effective and highly accurate face recognizer and scaled it to the computational resources of a mobile computer powered by a mainstream Intel® Atom™ processor.
This project complements a number of other Intel Lab research projects. The identity data can be used as an input for other context-aware computing applications, providing a reliable mechanism for personalizing apps and services for individuals. This project has already spawned practical applications, and the C++ code for the recognition and self-learning modules has been handed off to other groups at Intel for further development. Online semi-supervised learning also has broader applications that address the capabilities of a computing device to adapt itself to the behaviors of a user.
- Improve the quality of real-time machine learning on ultra mobile computing devices without asking for feedback (interaction with the user of the device)
- Develop algorithms that can progressively build a model of objects and enhance it over time
- Improve the accuracy of algorithms that perform face recognition
