Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 20:
21. An event detection device comprising:
a neural network encoder configured to encode a plurality of training video snippets into low dimensional descriptors of the training video snippets in the code space, including one or more labeled video snippets of a plurality of event classes;
a class cluster classifier configured to map the plurality of event classes to class clusters corresponding to the low dimensional descriptors of the labeled video snippets;
a neural network decoder configured to decode the low dimensional descriptors of the training video snippets into corresponding reconstructed video snippets; and
a loss function configured to adjust one or more parameters of the neural network encoder and the neural network decoder based on 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 entropy class entropy of the plurality of event classes of the code space, to increase fit of the training video snippets, and to increase compactness of the code space.
