Deep Learning from Temporal Coherence in Video

Description
This work proposes a learning method for
deep architectures that takes advantage of
sequential data, in particular from the temporal
coherence that naturally exists in unlabeled
video recordings. That is, two successive
frames are likely to contain the same
object or objects. This coherence is used as
a supervisory signal over the unlabeled data,
and is used to improve the performance on a
supervised task of interest. We demonstrate
the effectiveness of this method on some pose
invariant object and face recognition tasks.
