Curiosity as the drive to improve the compression
of the lifelong sensory input stream: interestingness as
the first derivative of subjective "beauty" or compressibility.

Optimal Artificial Curiosity, Creativity, Music, and the Fine Arts.
Connection Science, 18(2): 173-187, June 2006.
This paper emphasizes that beauty and interestingness
are different things: the former reflects low complexity with respect to the observer,
the latter the learning process leading from high to low subjective complexity.
