In this talk I will showcase the general theory of knowledge discovery through a few specific application problems. The first is the pattern change discovery in high-dimensional data, and I will demonstrate the theory in the scenario of event detection through pattern change discovery in text, imagery, and video, respectively. The second is the topic modeling and the trend analysis, and I will demonstrate the theory in the scenario of topic analysis in static text data and trend analysis in dynamic text data. The third is the image annotation with incomplete labels and I will demonstrate how we can complete the labels through knowledge discovery from given incomplete data which is a well-known and notorious problem in multimedia annotation. Depending upon the time, I will talk some or all of these problems. I will conclude the talk by arguing that multimedia knowledge discovery theory is powerful in solving many real-world problems.
