Talk Title: Kernel Methods for Domain Adaptation
Series: Student Seminar Series
Abstract: The problem of domain adaptation occurs when the test data (of a target domain) and training data (of some source domain(s)) are generated by different distributions. It arises in a variety of applications, including computer vision, natural language process, speech recognition, etc.
In this talk, I will present some of our recent efforts on unsupervised domain adaptation using kernel methods. One cannot solve the domain adaptation problems given arbitrary source-target pairs. We have to explore the structures or properties in data, under which potentially successful solutions exist. Kernel methods are versatile in modeling such structures or properties. I will demonstrate several kernel methods ("kernel trick", discriminative multiple kernel learning, kernel embedding of distributions, etc.) which have been successfully used to model the structures of subspaces, landmarks, and latent domains. I will also present a sequential determinantal point process (seqDPP) with applications to supervised video summarization. This serves as the starting point of my future work on domain adaptation for video analysis.
