Claim 9:
10. A event detection method comprising:
encoding a plurality of training video snippets into low dimensional descriptors of the training video snippets in a code space, including one or more labeled video snippets of a plurality of event classes;
mapping the plurality of event classes to class clusters corresponding to the low dimensional descriptors of the labeled video snippets;
decoding the low dimensional descriptors of the training video snippets into corresponding reconstructed video snippets; and
adjusting one or more parameters of the encoding and decoding based on a loss function including one or more objective functions selected from a group including to reduce a reconstruction error between the one or more training video snippets and the corresponding one or more reconstructed video snippets, to reduce a class entropy of the plurality of event classes of the code space, to increase fit of the training video snippet, and to increase compactness of the code space.
