报告题目：bridging topological data analysis and machine learning
报告摘要：topological data analysis (tda) extracts the topological features that are complementary to statistical quantities, which has been found in many applications in computer vision. in tda, persistence diagram (pd) has been considered as a compact descriptor for topological data analysis (tda). unfortunately, pd cannot be directly used in machine learning methods since it is a multiset of points. recent efforts have been devoted to transforming pds into vectors to accommodate machine learning methods. however, existing methods share one common shortcoming: the mapping of pds to a feature representation depends on a pre-defined polynomial. this presentation will introduce two recent advances: polynomial representation and hilbert representation for pd, with the aim of extracting the discriminative topological features. finally, potential applications in the field of computer vision, and biomedical science will be discussed.
