Caracterization of dependencies in sparse representations

dict struct learning
Source: Elad, Small Workshop, 2011.

Learning structures using the Boltzmann Machine (BM)

Main ideas:

  • A statistical model for the sparse supports takes the dependencies between atoms into account.
  • Such dependencies are caracterized by a matrix, as illustrated in the figure on the right.
  • Learning this matrix = learning the structures.
