Abstract
\nOne of the keys to success in machine learning applications is to improve each user’s personal exper ience via personalized models. A personalized model can be a more resource -efficient solution than a general-purpose model\, too\, because it focuse s on a particular sub-problem\, for which a smaller model architecture can be good enough. However\, training a personalized model requires data fro m the particular test-time user\, which are not always available due to th eir private nature and technical challenges. Furthermore\, such data tend to be unlabeled as they can be collected only during the test time\, once after the system is deployed to user devices. One could rely on the genera lization power of a generic model\, but such a model can be too computatio nally/spatially complex for real-time processing in a resource-constrained device. In this talk\, I will present som e techniques to circumvent the lack of labeled personal data in the contex t of speech enhancement. Our machine learning models will require zero or few data samples from the test-time users\, while they can still achieve t he personalization goal. To this end\, we will investigate modularized spe ech enhancement models as well as the potential of self-supervised learnin g for personalized speech enhancement. Because our research achieves the p ersonalization goal in a data- and resource-efficient way\, it is a step t owards a more available and affordable AI for society.
