Abstract:

For being able to act autonomously in its world, an agent has to
sense the world's state.  Sparse coding seems to mirror the structure
of natural scenes and signals.  Can this help?  We will give an
introduction to sparse coding and show how the state of a sparsely
encodeable world can be sensed very efficiently, e.g. by compressive
sensing or adaptive hierarchical sensing.  We show how signals can
be sensed very efficiently in an hierarchical manner with at most
k log D sensing actions, with D being the dimension of the signal
space.  This hierarchical sensing might relate to the way we sense
the world, with interesting applications in active vision.
