报告摘要(abstract):
in this talk, tsh shall first describe some recent research projects and ideas of his group related to the broad topic of image representation. at the visual feature level (low-level), we have recently developed hierarchical gaussianization (hg), a patch-based location-sentive representation, which is a kind of soft version of "bag of words". hg hs been applied to a number of visual recognition tasks (including face recognition and face verification) with great success. at the semantic level (high-level), we are exploring the use of ontology to help inference; i.e., to use the relationships between image/object classes/labels to increase recognition accuracy and even to come up with new paradigms of doing inference. the relationships of particular interest are: "is a subclass of", and "co-occurrence". we have developed several ways of taking advantage of these two relationships. finally, in many web-based applications, visual data (images and video) are often embedded in "heterogeneous networks" (hn), which may involve social media. hn have a wide range of applications. to name but two: personalized ranking and recommendation; collaborative trustworthy sensing (crowd sourcing and mining of trusted knowledge from social media).
in the second part of this talk, gjq will expound on "mining trusted knowledge".
