Building A Large Concept Bank for Representing Events in Video
[article]
2014
arXiv
pre-print
Preserved Fulltext
We train a Multiple Kernel Linear SVM for each discovered concept as a concept detector in Concept Bank. ...
To construct the Concept Bank, we first gather a comprehensive event collection from WikiHow, a collaborative writing project that aims to build the world's largest manual for any possible How-To event ...
Figure 1 illustrates an overview of how we build the proposed Concept Bank and use it to represent an event video. ...
