A working entropy encoder with output below the Shannon limit
Proof of concept entropy encoder with output size below the Shannon limit. - Peter-Ebert/Valli-Encoding
The data could be compressed easily (even zero counts are included), but this simple format shows that nothing is being hidden inside. I'm grateful and lucky to have had the chance to set aside time to work on this and never intended to make money off it, so any donations would encourage further research or improvements. Memory and storage are ample these days so the few bytes it saves may not seem significant, but it's worth noting that even a 1 bit reduction means we've reduced the number of possible values in half.
