  • Bijective BWT (7 Comments)

    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (113 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

  • Precomp: More Compression for your Compressed Files (3 Comments)

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

SharpEntropy Library

Posted by Mark Nelson on 8th November 2005 | Permanent Link

While toodling around on The CodeProject web site I bumped into this nifty article on the SharpEntropy library. This LGPL library can be used to do prediction and modeling of natural languages using something called Generalized Iterative Scaling. Only problem is, you’re going to need to buy into .NET to get this working.

Unfortunately, the CodeProject site is a bit sluggish at times, so be patient, the link really will work.
