Grammar-based codes: A new class of universal lossless source codes

  title={Grammar-based codes: A new class of universal lossless source codes},
  author={John C. Kieffer and En-Hui Yang},
  journal={IEEE Trans. Information Theory},
We investigate a type of lossless source code called a grammar based code which in response to any input data string x over a xed nite alphabet selects a context free grammar Gx representing x in the sense that x is the unique string belonging to the lan guage generated by Gx Lossless compression of x takes place indirectly via compression of the production rules of the grammar Gx It is shown that subject to some mild restric tions a grammar based code is a universal code with respect to the… CONTINUE READING
