A personalized model can be a more resource-efficient solution than a general-purpose model\, too\, because it focuses on a particular sub-probl em\, for which a smaller model architecture can be good enough. However\, training a personalized model requires data from the particular test-time user\, which are not always available due to their private nature and tech nical challenges. Furthermore\, such data tend to be unlabeled as they can be collected only during the test time\, once after the system is deploye d to user devices. One could rely on the generalization power of a generic model\, but such a model can be too computationally/spatially complex for real-time processing in a resource-constrained device. In this talk\, I w ill present some techniques to circumvent the lack of labeled personal dat a in the context of speech enhancement. Our machine learning models will r equire zero or few data samples from the test-time users\, while they can still achieve the personalization goal. To this end\, we will investigate modularized speech enhancement models as well as the potential of self-sup ervised learning for personalized speech enhancement. Because our research achieves the personalization goal in a data- and resource-efficient way\, it is a step towards a more available and affordable AI for society.\nBio graphy\nMinje Kim is an associate professor in the Dept. of Intelligent Sy stems Engineering at Indiana University\, where he leads his research grou p\, Signals and AI Group in Engineering (SAIGE).
