Mathematical Model of Surprise

A group of computer scientists have come up with a mathematical
to detect surprising features in dense information streams.
They tested their method by comparing it to what human’s considered
surprising, and the results were… surprisingly good! A mathematical
model of surprise could be very useful in next-generation information
systems, user-interfaces, situation rooms, and even fighter jet
cockpits, for filtering signal from noise and helping to focus
attention on what’s most important at a given time.
