An Online Framework for Learning Novel Concepts over Multiple Cues [chapter]

Luo Jie, Francesco Orabona, Barbara Caputo
2010 Lecture Notes in Computer Science  
In the first layer, we use a budget online learning algorithm for each single cue. Thus, each classifier provides confidence interpretations for target categories.  ...  We test our algorithm on two student-teacher experimental scenarios and in both cases results show that the algorithm learns the new concepts in real time and generalizes well.  ...  For multi-class problems, the algorithm is extended using the multi-class extension method presented in [17] ; we omit the detailed derivation for lack of space.  ...
