| Outline of Final Research Achievements |
The objective of this research is to develop a low cost event learning framework to enable easy event learning and recognition. The proposed framework has the following three components: (1) web data collecting, which helps to prepare learning data efficiently; (2) robust event learning, which guarantees the event recognition performance; and (3) domain adaption, which helps to transform the event models learned from the web domain to the target domain. In our work, we developed (1) a flexible event retrieval approach by integrating image recognition and nature language processing; (2) an approximate sparse coding based high performance event recognition approach; and (3) a feature selection based domain transform approach for adapting event model between different domains. The proposed objectives of this research have been mostly achieved.
