　　Abstract: In this talk, I will introduce our research on large-scale visual recognition through hierarchical learning of tree classifiers. First, a visual treeis learned for organizing large number of object classes and image concepts in a coarse-to-fine fashion, which can provide a good environment for determining the inter-related learning tasks automatically in the feature space. Second, a multi-task structural learning algorithm is developed to learn the inter-related classifiers for the sibling child nodes under the same parent node. An inter-level constraint is introduced to learn more discriminative classifiers for the high-level nodes on the visual tree.
