What's the absolute minimum you can compress data to? - Entropy conjures up visions of chemistry and physics, but how does it apply to binary codes and computer science? Professor David Brailsford continues his discussion of compression.
Addendum: the formula at 4:40 is the "weighted average bits for that state"
rather than the total number of bits - (log^2)
