PADDLE Documentation

Date:February 28, 2011

PADDLE is a Python package for learning dictionaries with frame-like properties, as well as achieving sparse coding of the training data. In particular, it provides algorithms for

  • learning a dictionary together with a dual of itself, and
  • learning a dictionary close to a tigth-frame.

PADDLE’s license is free for both commercial and non-commercial use, under the BSD terms.
