Another point about surprises: when considering information theory suprise is an important thing and only surprises make us learn something. Consider a channel that transfers only 1's. You cannot derive any information from the next 1 you receive (entropy = 0). If the channel spits out 0's and 1's you have higher entropy and higher information content. The entropy is related to the level of surprise you experience when you receive a symbol. http://en.wikipedia.org/wiki/Information_entropy In short: surprise isn't bad alltogether. Kind regards robert
